T470 + Windows 7 + NVME (Toshiba) = Inconsistent write performance

Q: T470 + Windows 7 + NVME (Toshiba) = Inconsistent write performance

I own a T470 with a Lenovo branded 256GB NVME drive, running Windows 7. The drive is thnSn5256gpuk according to device manager. Looks like this is a rebranded OCZ XG3/4 drive. --- I am getting fairly inconsistent write performance on this drive. According to both crystaldiskmark and as benchmarks, the write performance will sometimes be 700mb/s, other times 300mb/s. I can run the test once, it will show up 700mb/s, run again, and it will be 300mb/s. --- I have tried switching over to the ocz nvme windows 7 drivers, which work just fine btw. But to no avail, microsoft nvme drivers or the ocz ones, both have the same symptoms. --- Anyone able to get consistent write performance from this setup? --- NOTE: Please don't sudgest upgrading my bios, flashing the newest firmware on the ssd or making sure write cache is enabled in device manager... Or any of the low hanging fruit... I've spent about 5 hours trying to get proper (as per the spec of the drive, from the toshiba site) write performance on this drive.

My new purchased T470s laptop (Serial Number: PC0S7E53 Machine Type Model: 20HGS24J00) is equiped with a 256GB PCLe SSD. The SSD is neither Samsung nor Toshiba. It's called LENSE20256MSP34MEAT2A ?! I don't even know how to search the specs of such part, as there is totally no information for such ssd in Google! But the key point is the SSD obtained a relatively low write speed compared with other NVMe SSD. As shown in test record by crystaldiskmark, the write speed is only 160 MB/s. Is this normal? Is it possible to ask for a change of SSD? Because my purchase is still within 7 days. Also, the battery is not that long-lasting as it claimed to be (10.5 hours). I charged until 100% and use the laptop for document reading with some online search in Wikipedia. The battery performance has been set to "better battery" and I didn't play videos and music in the process. The battery runs into 17% in 4 to 5 hours. Although I didn't expect it will hit 10.5 hours, but it is too much beyond that???? Could everyone help me with this? Is it normal or is that any possible solutions? Thank you!

Hi everyone, I recently bought a T470 and it came with a Toshiba 512GB Nvme drive (I think its XG4). Just wondering if those of you with this drive are using the default windows drivers or the drivers made for the OCZ-RD400 drive as shown in this thread (https://www.win-raid.com/t29f25-Recommended-AHCI-RAID-and-NVMe-Drivers.html).I have read some comments on how there is poorer performance on this drive compared to the Samsung PM961 drive and I was wondering if you guys have noticed the same with the T470.Thanks for your input

I've observed that performance of my P70 is much less than I would have expected, especially noticeable when copying data from other machines on my LAN to a target location on either my Lenovo HDD or Samsung 950 Pro NVMe SSD.  Looking at the graphic in DUMeter for LAN traffic bit rate, it showed astonishingly low values that simply were unreasonable.
 
I'm concerned that something is very much not right, either with the hardware in the P70, or perhaps something in Windows (or the "tweaks" I did after cloniing from spinner to SSD).
 
I decided to perform benchmark measurements, and reference the results against either my own other hard drives on other machines, or against other user 950 Pro benchmark results posted by reviewers on Amazon for the product.
 
First up is to compare HDD numbers, and for this I looked at three hard drives on one of my desktop machines.  This machine is home-built based on an ASUS P8Z77-V Pro motherboard and i5-3350p CPU, 8GB of DDR3-1600 RAM.  I've inserted the Lenovo HDD where it fits, in terms of READ speed numbers.  However I was very surprised to notice that the WRITE speed on the HDD was MUCH LOWER than I believe it should show.
 
The first post here addresses the HDD in the P70.  It seems to me that READ speed is just fine.  But the WRITE speed seems MUCH LOWER than it should be.  If I am interpreting the numbers correctly, unless I'm comparing the wrong values (specifically the 4K number... Read more

A:P70 + HDD/NVMe WRITE performance disaster. Why??

Now for a comparison of the Samsung 950 Pro NVMe SSD performance, as measured by CrystalDiskMark and also AS SSD.  I used these two products because there are comparable measurements posted on the Internet for me to compare to.
 
I started running Samsung Magician Performance Benchmark, but it was going to run for an hour and I didn't want to wait.  The problem is that WRITE performance is SO HORRIBLE that things are taking forever to complete, when WRITE is involved.
 
Tell me if you agree with my conclusions, that there is something HORRIBLY WRONG WITH WRITE!!! 
 
(1) First, the CrystalDiskMark numbers.
 
(a) my P70 Samsung 950 Pro, CrystalDiskMark.  Note that WRITE numbers are  GEOMETRICALLY LOWER than comparable values available from others on the Internet.
 

 
(b) Internet user-A
 

 
(c) Internet user-B
 

 
 
(2) Now the AS SSD numbers.  Note that my NVMe has very deficient READ numbers compared to others per AS SSD although it didn't seem different using CrystalDiskMark.  But it is in the WRITE values where my NVMe is a COMPLETE DISASTER!  Seems like it's simply broken.
 
(a) my P70 Samsung 950 Pro, AS SSD.  Again, HORRIBLE WRITE NUMBERS.
 

 
(b) User-A
 

 
(c) User-B
 

 
 
 
Ok. What's going on here?
 
Could the card not be inserted properly?  How could it produce such astronomically low WRITE numbers, and yet ... Read more

We have just purchased a Zbook 15u G3 that has a Toshiba m.2 NVME drive in it. This is the first one we have gotten with this drive, as the others have the Samsung 951 drive. We use MDT 2013 to deploy Windows 7 to our PCs and laptops which I have the Samsung driver injected into the image as well as the Microsoft updates. The problem I am having is, when I deploy our image to the laptop with the Toshiba drive, I get the wonderful blue screen because I don't have the drivers for the Toshiba installing during the imaging process. I have the Samsung drivers loading and I can deploy with no issues at all, but cannot without the NVME drivers for the Toshiba drive. Is there anywhere I can get these drivers?

Before removing the HDD from my T470 I made a Clonezilla image.  I then installed the Samsung 960 and restored the image.  Unfortunately upon booting into Windows I was greeted with "Your PC ran into a problem and needs to restart", so that did not work.  I have done many Clonezilla images and restores, but not between two completely different drive technologies.  So if anyone has been able to get this to work with either a T470 or similar laptop, what cloning software did you use, and did you do it with an image backup/restore, or direct clone with the HDD connected to the laptop with either a SATA to USB, or SATA to USB-c cable (If that's the case what cable worked OK)..

That depends.  Are we spending your money or mine?
 
Given your use case I'd probably use the extra $ to go with a 500GB 2.5" SSD.  Then again, I'm a spec snob and might not be able to resist the NVMe drive.
 
As you've already figured out, the 470 only uses 2 PCIe lanes so that limits the NVMe SSD to something like 1700MB/sec.  The SATA unit would be more like 500MB/sec or so.  In practice, you'd probably never notice a difference.

I am on a JANET network connection and _should_ have extremely fast net access. In fact the connection can (momentarily) acheive very reasonable download speeds, but most of the time the connection appears to be doing nothing at all - activity is very sporadic and unreliable.

Borrowing a colleague's pc (less powerful than mine) and using the same network socket proved that there is nothing wrong with the connection itself (consistent download speeds of c400kbs from linuxiso.org), and the problem must be something to do with the way the connection is set up on my computer.

When I asked the tech support people here about it they poked around with lots of obscure-looking dialogue boxes before shrugging their shoulders and saying they couldn't see anything set wrongly in terms of the local network servers etc, so I think the problem is entirely local to this machine - something to do with the os?

System is athlon xp1800/512Mb/xp pro. Startup list is clean from rubbish; temp files etc deleted regularly; performance fine in other respects.

Any ideas? thanks in advance.

Hi everyone,
I just installed a new gigabit switch in my home network and tested the performance of the new network. I know that the test I did is not a good test, but I just wanted to know how stable it is and how fast copying a big file would be. Any suggestions on
how to do a good substantiated test are welcome.
Configuration is as follows. I have a Windows 7 Pro pc and Windows 7 Pro laptop connected to the switch. The test I did is copying a big file, on the pc, from the pc to the laptop and from the laptop to the pc. I did the same on on the laptop. The results
are (approx.).
On the PC
From PC to Laptop: 39MB/s
From Laptop to PC: 50MB/s - 70MB/s
On the Laptop
From PC to Laptop: 68MB/s
From Laptop to PC: 44MB/s

The hardware configurations of both systems are not exactly the same. The pc has an Intel i3 processor, the laptop has an Intel i5 processor. Both have 8GB of ram and an SSD harddrive installed. Both have gigabit adapters, but are different. I know all of
these things impact the performance of the network, better said, the performance of the file copy. But I can't really figure out the different results. For example, I expect the copy from the laptop to the pc to be faster on the laptop, but it's exactly the
opposite.
I hope someone can explain to me why the results are what they are. And maybe give me some advice to get the most out of the network.
Thanks for your help! Appreciate it.

I'm running windows 8.1 and have a wireless connection with a Qualcomm Atheros AR922 X Wireless network PCI card. I have looked at a million forums and have tried to narrow down my problem but I'm stuck.

My internet connection is very inconsistent. Some days I can stream video for hours, then suddenly I can't even look at my email. It does NOT appear to be my router because we have many other devices int he house which work just fine.

My signal strength always shows STRONG and I have worked on making sure I don't have anything blocking the signal to reduce quality. I even keep my cell phone in another room just so there's no interference.

Sometimes my internet connection stops completely. I disconnect from it in my network manager and then reconnect and I will get a sudden burst of speed that will last a minute or two, then dies off again.

Here's what my "Wi- Fi Status Currently" Says

IPv4 Connectivity: Internet
IPv6 Connectivity: NO network access
Media State: Enabled
SSID: (my network name)
Speed: 130 Mbps

Usually when my connection drops out the IPV4 will also say no network access even though my connection will still be strong.

Any ideas?

There are various levels of performance in NVMe drives - they are not all the same.  Your Toshiba drive is known for being one of the slower models out there -- you're never going to see barnstorming performance from it.

Hello, I've bought a Lenovo t470 that worked great for 6 months, and recently it started to slow down its performance heavily. Using Resources Monitor, I saw that the CPU was working at 100% even it didn't had any kind of programs open. I have already seen that this problem was very common on this laptop, and it also had a solution: the 1.39 BIOS update released in 2017.I updated BIOS and video card drivers, and none of this solved the problem. I also dug for days in forums looking for possible solutions, as battery performance settings, and others, and none of this worked. The laptop is using Windows 7 and the lastest driver updates. Any word of advice and also any help from official Lenovo employees would be kindly received. As a longlife Lenovo customer (more than 10 years and this is my fourth Thinkpad laptop) I'm really struggling to have any response from official Lenovo employees since I have been calling their tech support for 2 weeks straight with no response, and it would be a shame to have this kind of incident ending such a long-lasting relationship with the brand.

I have a Samsung 960 Pro NVMe SSD in my P51s, but the performance is about half what is expected.  I unencrypted the drive (bitlocker) and the random read/write improved but the sustained read/write did not.  The sustained read/write performance remained at about 1,700Mbps.   I have the latest 1.22 BIOS, the latest Samsung driver, and am running in UEFI mode.  The P51s uses a PCIe 3.0 bus, and this should easily sustain full 3,600Mbps performance.   Any ideas on what may be limiting performance?

I don't have a similar machine, but that does seem slow.
 
Can you pull the exact SSD model number out of device manager?

Hello, I've bought a T460s with a stock 256gb sata ssd and I wanted to upgrade it to a fast NVMe storage however there is an issue of speed. The stock drive works just fine as rated, however NVMe drive is incredibly slow, far below specification and in some regards even slower than a mechanical hard drive. Here are results : So in attempt of fixing the issue I have tried numerous things, here's a list.- First I tried the nvme drive in a different system to see if it's not faulty, it was connected through an adapter in my desktop system so the performance was sub par true potential, but still far above the speeds I'm getting with the laptop - my nvme drive on the left and my desktop 2.5 inch standard sata ssd on the right - the drive is certainly not the issue here- update the bios, the laptop I bought had stock bios on it, so I have tried updating it to a newest version with the meltdown/spectre fixes, that did not help, I have also tried flashing one below version to see if the meltdown stuff affects performance, but it does not- I looked into bios options if the drive is limited to sata or something like that, but didn't find any options there, win 10 was installed in UEFI mode- I'm running Win 10 PRO with all the updates as of 14.01.2018, I tried bootable ubuntu live usb and try benchmarking the drive with hdparm and the in built benchmark tool, same results as on windows, I have not tried Win 7 yet but I think I can safely assume that won't help either.- Some pe...

Dear Dell Community,
I have some problem with performance of SSD in my Latitude 7370.
Before I bought it I read some tests & reviews of this laptop, and performance of SSD Toshiba NVMe THNSN5256GPU7, 256 GB should be like this: 

but my SSD looks like this):

Current situation:

Windows 10
UEFI Bios mode
BIOS 01.06.03
secure boot on
GPT partition
SATA Operation: AHCI

Dell (phone) Support had completely no idea what to do, so they decided to replace the hard drive - since today I have Samsung SM951 NVMe, but everything is the same! Look:

OK, Read is even better, but write is still disaster.I have no idea what's going on..
Thanks in advance, and greetings from sunny Poland!Kuba

For a while now I have suspected that something wasn't quite right with my computer due to strange behavior and poor performance. Having no idea what the exact cause is because the problems are so inconsistent and sporadic, when it starts acting ?crazy? I do the usual; restart, delete temp files, scan for viruses, etc. and hope it gets better.Recently I received the following e-mail. I think it is a response to an e-mail I must have sent requesting I be Unsubscribed from something."From: [email protected]: Unsubscribe, click hereThe virus W32/[email protected] was found in click.bat. The attachment click.bat was removed.The virus Exploit-MIME.gen.b was found in . The attachment was removed."I'm not really sure what it means but I think that it means their server found these 2 viruses attached to my e-mail because my computer is infected with them. Is this correct? I'm a little confused because my anti-virus software didn't detect them. In addition, and I have tried other virus scans, as well as Symantic's tool to remove W32/[email protected] and nothing is found. Could it be that they are so far hidden in my system making them undetectable? Do I even have the viruses? How can I tell for sure? The only thing that my antivirus-software is detecting is the Win32/Iflar.O virus but does not offer any advice for removing it. Any help is much appreciated.

Microsoft has released NVMe Hotfixes 2990941 & 3087873 that add native NVMe drivers to Windows 7.
However if I am say installing Windows 7 SP1 on say Samsung NVme drive and Samsung has released suitable drivers in the form of INF, SYS and CAT files, do I really need to integrate these MS Hotfixes in Windows 7?
Can Windows 7 SP1 supplied with Samsung NVMe drivers (Either slip streamed or during install) be able to detect Samsung NVMe drive and install itself on to it?
As the title says are those MS Hotfixes a must (sort of pre-requsite) to get NVMe drive detected during installation, apart from any vendor provided drivers?
Thanks.

Almost everytime I am on battery power, this laptop slows down to a crawl. Any suggestions? Running Windows 10 ProCore i5 7200u Things that I've tried:1. Updating all drivers and BIOS2. Turning off battery saver within BIOS3. Setting the power options within windows 10, to have a minimum CPU performance of 50%4. Setting cooling to Active on battery (just in case it was thermal throttling).5. Updated to both the old and new version of Lenovo's Power Management Driver.  The above still has my laptop running @ 0.38ghz and it doesn't increase with load (not sure why).See screenshot:Peformance Snapshot

up until windows preview build 14986, the pcie driver "Mobile 6th Generation Intel(R) Processor Family I/O PCI Express Root Port #5 - 9D14" (v10.1.1.27) correctly detects the "Standard NVM Express Controller" storage controller and the Toshiba THNSN5512GPU7 NVMe disk attached to it. starting with windows preview build 15002 (and 15007), the included pcie driver has troubles detecting the storage controller - during bootup, it is detected 4 times, with each time on a different device id. subsequently, the drive is also added 4 times, resulting in boot controller errors & timeouts and failed sleep mode/shutdowns. the included chipset driver in these latest builds seem to have been bumped to v10.1.1.33. the problem can easily be replicated by using unmodified recovery boot usb sticks made from the official isos, and then checking in a recovery console. it is thus not related to anything installed in my system.

Hi,

I'm not getting full speed from Samsung SM951 NVMe 512GB drive,  while other reported almost double the speed I'm getting from Crystal mark.
I tried everything from using latest Samsung drivers, Microsoft NVMe drivers, updated the bios and disabled "windows write-cache" with no change whatsoever to the numbers.
I'm suspecting the Firmware used by dell cap the drive to reduce the TDP, but getting half the speed is very disappointing.
This is what I'm getting
and these what other people are getting

I just received my M7710 with a 512GB M.2 PCIe NVMe High Performance SSD and Windows 10 Pro 64-bit.
My intent is to install two similar 1TB drives myself as the 2nd and 3rd drives (which were options when customizing the system).
I'm looking for complete instructions on how to do this. It seems the Dell online manual is either out of date or hopelessly vague, as it does not mention installation of a 2nd or 3rd drive of any kind (that I can see).
My ability to accomplish this is a make/break proposition and will determine whether I keep this machine or return it.
Thanks.
Tom

A:M7710 - Installation Instructions 2nd and 3rd M.2 PCIe NVMe High Performance SSD

If you look at the list of options, it appears that the system supports two M.2 NVMe drive on the board (the position is shown in the manual).  The other option fits into the 2.5" drive bay in place of standard 2.5" drive -- one mentions requiring an interposer, so you'll likely need to contact Dell to buy that.
No configuration mentions the option for three native M.2 drives in addition to the 2.5" drive bay capacity.

I recently purchased a Intel 600p series nvme ssd and plugged in this tiny lady. But she seems get a bit over hot when get this small powerful stick in the body. A similar thread has uncovered this problem, probable due to the UEFI power control. The temperature is staying arround 60 C when just surfing the web browser and writing emails. The performance gets unstable when engaging copying large files and loading-demand programs, temp. up to 70 C or higher. Then I have to cool this little finger down by removing my sata ssd from the slot above to bring more airs in. This m900 tiny works perfectly with normal 2.5 sata ssd but not able to handle this m.2 little finger well. I am not sure how many m900 users here and would like to update the harddrive to nvme. Just want to draw the attention from lenovo to fix this problem.

I am wondering what the best choice is to squeeze the best performace out of this NVMe SSD. Some say chance the bios setting to ACHI and some say use Intel RST Premium.  I read this post from reddit:The issue is that Lenovo was making use of a disgustingly ugly hack to make it appear that a NVMe device was attached through an ACHI controller. Intel apparently added this functionality to recent chipsets as a shortcut to adding NVMe support to their fake RAID system. This feature is mostly undocumented and completely unwanted by anyone running Linux or using OS-provided software RAID under Windows instead of Intel's software RAID. So far, Intel has not convinced the relevant Linux kernel developers to add the necessary hacks to the Linux NVMe and AHCI drivers.In any normal situation, a motherboard firmware setting for AHCI vs RAID vs IDE modes has nothing to do with PCIe SSDs, because they do not connect through SATA ports. There are no PCIe SSDs on the market that the user can toggle between NVMe and AHCI, though there are still some AHCI PCIe SSDs that are based on the same hardware as their NVMe equivalents and are simply configured in the factory (permanently) as AHCI devices instead of NVMe. If a machine purports to offer a firmware option to change between AHCI and NVMe modes, it is lying to you about what that option means. If the choice is between AHCI and RAID modes but it affects PCIe SSDs, then selecting ACHI mode probably means the system will operate in a... Read more
