NAS RAID configuration question

Q: NAS RAID configuration question

this is my first NAS device. what raid config should i run? JBOD, RAID 0 (striping), or RAID 1 (mirrioring). I am using the NAS primarily for storage. however, i want to stream video from it as well. i am going with two WD black edit 1TB HD's.

Preferred Solution: NAS RAID configuration question

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

could I add an internal non-raid hard disk drive to my computer and leave my 3 other hard disk drives in a raid 5 configuration?
ASUS tech support said that I could add optical DVD/CD drives to my SATA connections on my mobo is that correct? The mobo manual does not indicate that I can so I don't know if I should believe the tech guy or not (unless the information is buried deeply and briefly in the manual - I sure can't find it in the manual). My IDE controller on the mobo seems to be failing so I want to replace my IDE dvd and cd drives with SATA optical drives.

I need to set up three user accounts on two computers the accounts on each computer is going to be monitored.
Each user will be assigned access for certain folder or files and certain applications, like internet explorer.
And all usb ports and dvd drive will be blocked. Only the admin will be allow to have full access.

So i need to do something that allow ( managers) to monitor employees activity on the system during working hours.

On one pc is windows xp pro on the other os windows 7 home premium.

Any idea how i can acomplish this task?

I.was thinking of group policy on both computers but on home premium there is not group policy.

Also the users will be using almost all the same programs and files just the with different information.

Thank you in advance.

But for Windows 7 Home Premium you will not have the
Local Security Policy so you may need to upgrade to Windows 7 Pro for that.

This is easier to control with a server like Windows Server 2003 or 2008.

A:Solved: RAID boot issues - disappearing disk - RAID question

Read other 8 answers

Hello. I installed a Raid 0 configuration recently. Motherboard Asus P5Q pro, 2 Samsung 1T HD. The board manual indicates that the raid disks must be connected to ports 0,1. They don't seem to be working though, so I tried ports 4,5, and it went well. Windows 7 recognized the disk and installed normally, the performance is reasonably good. In device manager I have the raid disk entry as well as the Intel raid controller. My question is: could it be that some "software raid " was configured, and that a better performance could be possible (if the ports 0,1 were ok)? Thank you.

From what I have read about Raid...Other posts.
Windows 7 is largely allergic to RAID. None of the standard troubleshooting steps work with RAID either, so we are at a loss here to help until someone familar with the dated RAID technology (rarely) steps forward.

what is a raid 0 configuration and what do u need for it? does it make your computer faster and how about would i go in making one?

A:What is a raid 0 configuration?

Raid 0 can be read as "no raid". It is a two drives together acting as one. It is faster than the two drives singly but there is no fault tolerance. If one drive develops a problem you lose the data on both drives.

Use it where speed is essential, but preferably only for temporary use and store your data elsewhere.

See http://www.acnc.com/raid.html for a tutorial on RAID

Any opinion is more than welcome.

My pc was configured in raid5 but I lost all the data. Since then I decided to go back to the classic drive C,D,E each by themselves. The point is that things are going slow / sometimes I try to access drive D with music and there is a significant latency in the hdd response. I can even hear the sleepy drive waking up.
I might want to aim to high but here is what I dream to do.
1. I want to go back to a raid configuration in which all those hdd(i have 3x 500 sata) to work hard for me.
2. Find a way to add the fourth one in which to save important data. I case of crash to reinstall vista and all the soft without losing all my projects. I am doing video editing.

My PC config is as it follows:
2x ATI RADEON HD 2600 XT - crossfire
4g memory - SUPER TALENT T800 UX 4G C5
3 X 500 G HDD SATA.

My motherboard has a sata external connector.

What would you guys do with this configuration in order to set up a raid. Don t tell me trash it 'cause i won t. I paid more than 4000 bucks last year. Today might value less than
2000 ( hurts so bad). This is another reason I want to squeeze as much as possible from what I have.

Back to the question - Can I add a fourth EXTERNAL HDD to the three internal I have. The fourth sould be the one for holding all the projects and data/ the other three just for ACTION. I would like to have only two for ACTION and the other two(one internal one external) for STORAGE.

A:Can somebody help me set up a raid configuration?

Hi tonitsaurus everything you are asking for in this post is possible.

Let's try this, raid 0 two of your drives for C: and one as D: for data and/or backup, when runs out of room add another, internal or external they work the same. (my system's window experience index different between raided and unraid is 5.9 to 5.5)

You will have to free up two of the drives and have everything you like to keep save to you C:. If not enough room save them else where like DVD's or somthing.

About the raid controller, I heard people refers it to be "real raids"; sounds like it must be better. However, you have consider more card means less room for your x fire to dissipate heat. It is up to you.

Now set up the two free drives to raid 0 array, make sure it is set up to be bootable. When it is done, it boots up as a new drive with new letter assigned.

Then marrow C: into the new drive, I use Acronis TI.

When done, shut down and disconnect original C:. Reboot with the new C:. Shut down and reconnect original C: which will boot up as a new raw drive you can format and do what ever you like with it.

I wouldn't worry too much about raid 0 is being relatively insecure. All you need is system backup every once a while in case of crashing. It can be easily system restore with Acronis.

The process would very likely work for you 'cus I did it before. Good luck and post back.

Dear all

I want to practice how raid disks configuration works but i don't have raid controller on my pc. I have hard disks and pcs. Is there any way to configure raid in virtual environment or without raid controller. please help

A:raid configuration help

Labist I have moved your post from networking since raid does not apply to networking.

If you have no raid controller [which severely limits your ability to train] your only option is to bring up a server system which supports doing software raid.

I would suggest you start with memorizing the most common raid levels [0, 1, 5, 6, 0+1, 10] and how they work.

You maybe able to find some virtual raid practices on the net by using google.

Best of luck.

My new Asus motherboard supports different Raid setups. I understand the differences between RAID 0 and 1, but it also says it supports Raid 0+1. No information is given however on how to set this up. The motherboard also has two sets of connectors SATA and SATA_Raid. The manual (you would think that a big company like ASUS would have someone with a command of the English language proof read their manuals) says to plug the hard drives into the SATA connectors and not the SATA_Raid. Does that sound correct?

hello everyone,

I am thinking to renew the whole data in current raid1 array md0. My environment is:

raiddev /dev/md0
raid-level 1
persistent-superblock 0
chunk-size 16
nr-raid-disks 2
nr-spare-disks 0
device /dev/hdb1
raid-disk 0
device /dev/hdd1
raid-disk 1

this '/dev/md0' is /home, so I'm not booting from this disk and the other file systems including root and /boot are on /dev/hda.

What I want to do is to renew the whole data in /home.

Is there any way to do this by switching /dev/hdd1 with all new data copied, then sync this new data to the other raid disk (/dev/hdb1) : FROM /dev/hdd1 (the disk just added with new data) TO /dev/hdb1 (currently active raid disk)??

Usually, after switching the HDD to new one, data in /dev/hdb1 is to be copied to /dev/hdd1 for recovery. But in my case, I want to do the opposite.

I would be so appreciated by all your helps,
Thank you,

A:RAID question: how can I renew the data in raid array?

I'm not sure what you want to do.. You want to copy something to the /dev/hdd disk (from another computer maybe) and then copy the data from /dev/hdd to the RAID array?

Since you are using RAID1 then it should be fairly simple.
You just simulate disk failure by removing /dev/hdd. You could do this by making the hdd drive hdc instead (jumper it to be the secondary master). Now you mount the "hdc" drive (that really was you hdd) and copy whatever you want to /dev/md0.
Since it's a RAID1 array then all the data that goes to md0 is written to hdb and when the /dev/hdd comes back the RAID is syned onto both disks again.

I'm not sure if that makes any sense to you. Can't be less obscure than your post though

I am in the process of restoring some bad sectors on a drive that is in a RAID 0 configuration using HDD Regenerator by Dmitriy Primochenko. Assuming I am successful without losing any data, I have the following question. Forgive the ignorance on this issue.

What is the best method to backup a RAID 0 configuration on to a drive on an IDE controller? What are the best moderate cost utilities to do this? Ultimately, I would like to be able to schedule a daily backup from within Windows 2000 and automate the backup process.

I have Norton Ghost 2003 (haven't used it yet). If it is installed on the RAID 0 drives running Windows 2000, can I simply have it take an image and put it on the other drive. If possible, how is this done? Each of the drives in my RAID configuration are 40Gb and the drive I plan to put on the IDE contoller will be larger (i.e. 120GB).

Will Ghost take an image of the entire 80Gb partition and allow me to put in on the 120Gb drive or do I need to partition the drive into two 40+ Gb partitions and image each drive. Now the question is does this have to be done from a boot disk? Windows sees the RAID 0 Configuration as one 80Gb drive.

Out of curiosity what would Windows 2000's backup utility do for me that is of value considering I am using RAID 0? I am not clear if it would backup all my data and put it on another drive.

A:Backup RAID 0 Configuration ?

I just found this site by typing ""backup a raid 0" and "to a single drive"" in a search engine... This was the only result of the search.

I like the professionalism of the posts and replys I've seen so far here. I think I'll stick around for a while.

I have two 74 gig Raptors.... I want to set up Raid 0 with them.
The reason is not to benifit from any performance possibilities... I know it probably ain't gonna happen. What I will get is a 150 gig (approx) 10,000 RPM SATA WD Raptor hard drive. I also know there is no fault protection with this setup.
Additionally, I have a 7200 RPM 150 gig SATA drive and a Kingwin SATA Mobile Drive Rack.

I want the performance of the Raptor with the volume of the 150 gig drive.
I religiously do my full system virus scans (yes, real time scanning is always on for front-line protection), and system defrags every Sunday evenings.

It's not a big deal to engage the internet lock after the system is done doing it's thing, take advantage of "hot swapability", slide the carrage with the 150 gig drive into the rack and do my system backup while I get ready for bed. In the morning, pull the 150 gig drive out of the rack and put it on the shelf / in the safe, disengage the internet lock and get on with my life.

I do have the onboard RAID controller. This will accomidate my RAID 0 setup. My question is, are there specific things I should look for when I pick up a secondary... Read more

Hey jbasagoi,

You seem to be talking about more than one problem here,

I have never heard of this before but;
GrooveMonitor.exe appears to be a program from Microsoft that is installed with Office 2007 It also appears to be spyware. Not only that it is apparantly used to conceal Viruses and Trojans.

I think some scanning against Virus's, Trojans and Spyware is called for

As to the RAID Problem you would be advised to back up your Files in case of total failure as your PC is just a couple of months old I suggest that you take it back for repair

I hope this helps

I have 3x 250gb sata 7200rpm drives.

I would like to know the best way to set up for SPEED using raid, but also have a small partition that is raid-1 and will be used for important information.
For example, is this a good setup (and is it possible):

500GB as RAID-0
under this 350gb i would have 2 partitions. The first being the OS (c drive), which I would like to do 16kb cluster size. The 2nd I want a large cluster size as I will keep large files in it. Is this a good idea?

125GB as RAID-1 (the remaining 250 divided by 2)
1 partition (probably NTFS), to hold important data.

What would be the recommended STRIPE sizes for each of those RAIDs?

The raid-0 will be used for the OS and will be mostly a gaming computer but also a lot of web browsing. not really any video/sound editing of any kind.

The raid-1 will be just be safehouse for any important data.

or is it better to just have 2 in the raid-0 and leave one out of the raid?

A:best way to set up this raid configuration with 3 drives, need help now! thanks

Levaing the third one out of RAID could be a way to do it. You can always save the important files both to the third drive, and on the RAID setup, so in case of drive failure, you'll have one copy left.

I have a PC running XP SP3 with an ASUS A8V deluxe motherboard, a single internal hard drive (shown in device manager as a Promise 1+0 stripe/RAID0 SCSI disc drive) and a VIA Serial ATA RAID Controller. It also uses the fast build utility. I want to take RAID off the drive and make it a simple disc drive so I can move to a dual boot configuration with Ubuntu. I tried simply changing the BIOS configuration from RAID to IDE but the system kept re-booting once it got to the windows startup screen, which I think was probably caused by the relevant driver not being installed or is it something more fundamental? Can anyone advise what steps I need to take to remove the RAID configuration, and whether I can do it without having to reload XP afterwards. Thanks

A:What do you need to setup a RAID configuration?

1. You need a motherboard with RAID capability or add-on RAID controller
2. I suggest you Google for types of RAID Arrays, and Data redundancy
3. The RAID controller will do this for you. You will have to reload the operating system if you change or add a RAID array drive if you don't use an array with data redundancy.

I have a stripped RAID array with no data redundancy. This is for maximum data access speed. It is made up of 3 500GB drives, giving me 1.36TB single drive. You think it would be 1.5TB, but because of "overhead" the total usable space is 1.36TB. I have a 4th 500GB drive for back up that's not part of the RAID array

I'm having some trouble trying to install Win7 the way I want it.

I have 3 hard drives on a nForce 570 Ultra RAID controller, with 2 80GB set up in a RAID-0 configuration, and a standalone 500GB drive with 2 partitions, one larger and one smaller, both for stoarge. I currently use XP Pro SP3, and it's configured such that the boot files, XP system files and Program Files folder reside on the RAID array, and my Documents and Settings folder reside on the larger partition in the 500GB. I'm planning do to a clean reinstall of Win7 with basically the same set up, with Windows system files and boot on the RAID array, and the Users folder in the larger partition on the 500GB.

I'm having 2 issues:

1. I created an Unattend.XML with the ProfilesDir set to E:\Users (the larger partition on the 500GB) and put it on USB for Windows Setup to pickup. But somehow Windows Setup still insist on creating the Users folder on the RAID and ignoring it.

2. Setup always tries to create the BOOTMGR in the smaller partition on the 500GB, which confuses my BIOS, as it tries to look for the boot files on the RAID, and all I get is the "BOOTMGR missing, hit C+A+D" message. I read up on some places that one way to solve this is unplug all non-RAID drives (i.e. the 500GB), however this creates the dilemma that I need the drive to be plugged in to create the Users folder.

Are there any ways to get my setup created? I don't want any data residing on the RAID, just system and program files.

Hi. I currently have two 500GB HDDs set up in a raid 1 configuration and am also regularly backing up the whole drive to an external USB drive. The raid is running through a PCI RAID card.

As I now need more space, I have decided to scrap the RAID 1 alltogether (as it is not necessary now that I back up to USB) and change it to a RAID 5 giving me 1TB of storage on a single partition. I have also bought another 500GB external drive for the additional space needed to back this up.

I just have a couple of questions: Will this be as straight forward as going to my RAID config screen and changing the RAID type? Will it wipe all the data from the hard drives? Is RAID 5 the right one to use or is there a better alternative? The reason I am doing it like this (and not setting them up as two seperate 500gb drives) is because I want to have everything on both physical drives showing as one large partition as this is mainly for storing media and it would be difficult to manage if it was split over two drives.

The OS is installed on a seperate drive so this won't be affected.

As common, the Intel Matrix Storage Manager and windows console controls all HD's within the Vista Ultimate x64 system. Now there are a few problems with this setup, for instance one of the Velociraptors went offline for 2 months, was standing by again last week, meanwhile the raid 5 array was 1 HD short so I had to let my Samsung 1 TB become the new array member. From the Intel Matrix Manager console, once in an array there are 0 actions that you may perform for a HD, so taking a HD out is no option.
Second problem I found after installing a new 3TB Seagate, it was reported as non allocated tough the Intel Console did display it as a non - array member.
Ok, getting the restored Velociraptor into the array, the action from the console only permits to chose between non-array member or spare array member, I solved this by simply disconnecting the Samsung HD so the system had to pull the third Velociraptor into the array again and make it an active array member.
The Seagate I could allocate as drive F through the discmanager, but, big disappointment, this program only sees it as a 750 Gig HD instead of the 3TB it actually is. Now is there any decent program to make me allocate and format it to its full size? I already installed the program form http://www.partition-tool.com/per... Read more

Hello I have a dell optiplex 990 and I cannot create a new raid.

I have a SSD for my main drive.  But I want to create a raid 1 with two spare drives I have just as a storage volume.

When booting CTRL+I does not do anything.  Even though the OROM is enabled.  I have the Intel Rapid Storage software installed and it does not allow me to create a new raid.

A:Dell Optiplex 990 raid configuration

my experience with the 990 minitower is that the drives need to be physically connected (SATA and Power cables) for the RAID1 "Ctrl-I" set up screen to appear. the above may seem very weird, but you may find it true, like I did, after experiencing huge frustration  trying to configure RAID1 before the extra drives are physically connected. (actually I was trying to do RAID1 configuration boot array before imaging with MS SCCM from a server in central IT)

I have two Intel X25-M solid state disks (80GB) that I want to stripe and use as my OS drive. I have the Asus P6T motherboard with ICH10R and support for RAID 0,1,5 and 10. My problem is I need to clone my OS partition with True Image and copy the volume to the striped drives. Here's the catch, my OS is already on one of the X25's and I will need to use an X25-V as a temp boot drive in order to stripe the two drives and still be able to use Windows for cloning. I also have 2 or 3 other SATA drives that I do NOT want to be configured in RAID.

So, I guess my question is will the striped SSD's take the cloned partition or will I encounter issues coming from a single drive? I don't have a ton of experience with RAID but I haven't had any problems either, but I want to play it safe. Any help would be helpful; I'm sure there is someone on here with much more knowledge on this matter. Thanks in advance!

I was forced to replace my OS HDD after a failure. My original configuration was my OS on HDD #1 and then two 1TB HDD set up in raid 1 configuration.

I purchased a Crucial 256gb M4 drive for my OS with the hopes of continuing to use my HDD #2 and HDD #3 as one drive in raid 1 for my data files. Upon reinstall Windows 7 booted right up but no longer were my two drives recognized as one drive. I went into the bios and changed my setting from ACHI to Raid and set the M4 as the first boot device. Upon restart no boot device was located and windows failed to start. I was able to <control-i> into my raid settings and the two 1TB are set up as raid 1 and the M4 is set as non raid drive.

Can anyone offer any suggestions as to why I am not able to regain my original settings?

A:Can't regain raid 1 configuration on HDD 2 & Hdd 3 after HDD 1 replace

The problem is you installed Windows 7 in AHCI mode when you reinstalled on the SSD. When you switch to
RAID, it needs to be told to use the RAID drivers.

Here's how:

Change the BIOS back to AHCI so that Windows 7 can boot.
I would temporarily disconnect the two 1 TB drives.
Then follow this article.

Error message when you start a Windows 7 or Windows Vista-based computer after you change the SATA mode of the boot drive: "STOP 0x0000007B INACCESSABLE_BOOT_DEVICE"

After the fix, reboot and now set the BIOS to RAID.

I am troubleshooting a RAID 5 configuration on a Window XP Pro machine. It was being used for data storage on the network. At some point I lost connectivity to the network drive (RAID)? I also had a network bridge which has disappeared as well? The machine has 2 NIC's installed on it which I don't understand its purpose for 2 NIC's? So as a temporary solution I copied the data on an external hard drive via USB. Then connected it on another machine and made it a shared network Drive. Any suggestion on restoring my RAID 5 array connection and network bridge? I have 3 stations, 3 switches and one Router.

A:Lost connectivity to my RAID 5 configuration

Uhm.. If you lost access to the RAID and the data, how could you copy it to the eternal drive? Or, do you mean that other computers could no longer access the machine with the raid array?

There is a big difference between network access and local access!

Hello Guys I need the experience of some of you relating to the installation of Windows 7 on a GPT partition.
My Boss  gave me a Dell Precision T5810 workstation, and for all I know it came with a factory configuration with three disks 2TB configured in RAID 5, but without Operating System.
He asked me to install Windows 7 and so I tried it but still did not succeed.  On initial installation I provided the RAID controller driver but after that  I am not allowed to do anything on the disk partition.
What I find is the following partitions:
Disk 1 Part 1 ESP 500M
Disk 1 Part 2 DIAGS 40GB
Disk 1 Part 3 OS 2 GB
Disk 1 Part 4 UNALLOCATED SPACE 3700 gb
As mentioned on any of the four partitions i can't do anything  even eliminate them,  and I get this error:
Windows can not be installed to the this. The selected disk is of the GPT Partions.
Now my doubt is Windows 7 can not be installed on GPT partitions and I have to convert force into MBR?
The Four partitions found in your opinion were created when the RAID 5 was configured? 
If i have to convert to MBR i can delete all the partition in order to installa Windows?
Thanks for the GIOvanni

A:Install Windows 7 on GPT Partition and RAID 5 Configuration

If you used Microsoft's USB DVD Download Tool your installation media is a major.  Microsoft's USB DVD Download Tool formats the USB Flash Drive to NTFS causing the computer to not recognize the UEFI boot files.  With Windows 7 the USB Flash
Drive must be formatted to FAT32 to enable the UEFI boot files to be recognized.
The two following links have information about preparing the USB Flash Drive to enable UEFI booting and UEFI installation:

My Computer Configuration:
(1) 128GB Solid State Drive (windows os)
(4) 1TB (set in a raid 1+0 configuration)

Here is the MYSTERY:
I am currently booting to my ssd in ACHI Mode.
yet the 4 hard drives show up as a single hard drive with a capacity of 2TB in explorer.

The Question is:
are the 4 hard drives actually working in a raid 1+0 configuration?
Is this even possible in AHCI Mode?
if this is not possible, then what is happening?


(other details)
when I change the Sata configuration to Raid mode and try to boot to the SSD i get this error message:

Info: the boot selection failed because a required device is inaccessible

A:Can a Raid 1+0 configuration work in AHCI mode?

4 hard drives in a raid 10 will show up as 2TB. It is composed as follows:

2 pairs of mirrored (raid 1) disk with a raid 0 stripe across the disks. Each mirrored pair is 1TB and you stripe across two of them giving you 2 TB.

Yes, it is probably working.

AHCI or IDE mode should not matter. Are you setting the SSD device to raid mode? If so, that is the source of your error - you need at least two drives to do any type of raid.

Hi Everyone,

In the past I have created a variety of RAID arrays using mechanical drives. As a general rule of thumb I found the data throughput with RAID 0 to be an 80 - 90% speed increase when compared to one drive acting alone.

I am now considering setting up a RAID 0 array using SSDs, more specifically I am looking at purchasing 2 x Corsair Force 3 240GB SSD.

What kind of performance increase can I expect from RAID 0 (of the BIOS variety) when compared to a single SSD? Is it better to pay more for a higher performance SSD and forget about RAID 0? Finally how does RAID 0 affect the life span of an SSD.

Any input here will be greatly appreciated.

Kind Regards,

I am configuring a Dell workstation to buy to use mainly for computer graphics (mostly Photoshop work). I am going to choose the SATA option.

I would like to know whether to order RAID 1 or RAID 0. I like the idea of duplicating information on the second hard drive if that is what RAID 0 does. Does that mean that if one hard drive fails, you will have all the information intact on the second drive?

RAID 1, as I understand it, uses striping and if you lose data on one, it is not recoverable. Is the advantage of this configuration speed?

Is it possible to have an additional (third) hard drive to use separate from the RAID drives (not another RAID pair)?

I would appreciate any advice you can give me. I am planning to get my work station with Windows XP Pro installed (not Vista).

Thank you if you have read this far--and thanks for any help you can give.

Hello. I'm setting up an ASUS K8V SE Deluxe motherboard with two Maxtor 80gig SATA-150 drives in a RAID 0 configuration. I plan on having a third, standard ATA-133, drive to backup the RAID 0 drives using something like Norton Ghost.

Here's my question: What is the best way to set all this up from both performance & reliability standpoints? The standard parallel drive will be more than large enough to both backup the SATA RAID drives as well as use for additional storage.

Here's what I'm thinking, let me know if anyone has any better suggestions: I will partition the PATA drive to contain a partition just big enough to backup the 160gigs of RAID 0 drive space, and have a second partition for other data.

What I'm not sure about is whether to install XP on the RAID 0 array or on the ATA-133 drive (remember, I'm looking at both performance AND reliability here). Then, should all my applications be installed on the RAID or the ATA?

My laptop has two SSD drives that run in RAID 0 configuration (so it's hardware RAID, not software RAID, but specifically RAID 0, where data are stored across two drives, not mirrored).

I am currently running Windows 8.1 Pro 64-bit and ran into some difficulties when I turned on Bitlocker. I was able to get my computer back to functioning, and Bitlocker says that my drive is now fully encrypted, but I have an error message from
Intel, which is how we discovered that my drive is really two drives with RAID 0. I'm wondering if anyone knows much about this. Specifically:

Does Bitlocker in Windows 8.1 Pro support RAID 0 -- should I trust that it's actually fully encrypting my data and won't cause problems going forward, e.g., if I de-encrypt and re-encrypt to change the Bitlocker settings or upgrade my OS?


Would upgrading to Windows 10 Pro, which I haven't done yet but plan to do eventually, result in Bitlocker working better with my RAID 0 configuration (e.g., is RAID 0 newly supported in Windows 10 Pro?)?

I haven't been able to find information about Bitlocker and RAID 0 that is current enough to answer my questions.

Hello Everyone,

I purchased two WD Green 500 Gig SATA hard drives. I currently have one WD 80 gig IDE as my master and a WD 40 gig as my slave. I am running windows XP Home addition. I want to change out the hard drives, but I have never used SATA before therefore I am a little worried about doing this. I read my manual under the RAID setup topic. I am undicided as to RAID 0 or RAID 1. I have backed up my C drive (the 80 gig IDE) and the slave through the software provided on my external 1 TB WD Book drive. I was thinking of using this software called Spotmau that I purchased to make a copy of my C drive for they say you can completly copy everything even the operating system. A tech at Best buy told me that the system will run very slow if I were to do it using the Spotmau software. He said it would be better to install the new SATA hard drives, set up the RAID and then place a new copy of my operating system on the drive, then pull over my files from the WD external drive. He said the USB can not copy the windows operation system and it would run extremely slow. I know there are a few topics here in my questions, but if anyone can provide some solid advice I would appriciate it. Basically I need to know more on what RAID to use and how best to copy my files over to the drives once there in. I have heard that using both IDE and SATA at the same time can not be done, That is what I planned on doing, but since it is not possible and they will not communicate with one anothe... Read more

A:Changing hard drives from IDE to SATA With a RAID configuration

Windows XP is not capable of running SATA drives as either AHCI (single drive SATA mode) or SATA RAID without installing the proper drivers during the OS install. You would be instructed to "Press F-6", then insert the drivers with a floppy drive.

Bottom line, you would have to install the OS clean to do what you want to do, no exceptions.

You cannot change the drive mode with the OS installed in either Vista or Win 7 either, but the driver situation is a bit easier to deal with.

I don't think the RAID 1 or 0 should be an issue. RAID 1 is a mirroring (backup) strategy, and RAID 0 splits data between 2 (or more drives) for speed of access. Truth to tell, RAID 0 really isn't any good by itself, too unreliable to protect sensitive data. You really need to run RAID 0 & 1 together, This is sometimes referred to as "RAID 5".

If you can be talked out of RAID altogether, you can run your new HDDs as is, by selecting "IDE" emulation in the BIOS. Most sources state that there is very little to no speed penalty for doing it this way.

Anyway, you would need to go to the board manufacturers website for the SATA drivers. I didn't Google your board. Does it even have a RAID capable SATA controller?

Incidentally, those WD "Green" drives are the worst possible choice for RAID. As I understand it, their "energy saving" self-throttling behavior, will cause them fall out of RAID, and generate a bunch or err... Read more
