The Samsung 950 Pro PCIe SSD Review (256GB and 512GB)
by Billy Tallis on October 22, 2015 10:55 AM ESTAnandTech Storage Bench - Heavy
Our Heavy storage benchmark is proportionately more write-heavy than The Destroyer, but much shorter overall. The total writes in the Heavy test aren't enough to fill the drive, so performance never drops down to the steady state. This test is far more representative of a power user's day to day usage, and is heavily influenced by the drive's peak performance. The Heavy workload test details can be found here.
Performance of the 950 Pro is comparable to the SM951, which is to say that it's significantly better than everything else we've tested. The penalty when starting with a fill drive is a bit larger than normal, but simply being full isn't enough to tank the performance the way a sustained test can.
Average service time and latency outliers are vastly better than any SATA drive, but NVMe doesn't seem to make a huge difference.
The high performance comes with the price of high power consumption, and the total energy used over the course of this test is significantly higher than all the high-performance SATA drives we're comparing against.

If you really need it FXi there is always the announced Samsung SM953 drive.It's 110mm long due to the inclusion of the tantalum capacitors, otherwise it's very similar to the SM951...

i was under the impression that win7 (install disk) does not support nvme, so i'm curious as to how you went about getting Win7 on a 950?Kristian Vättö - Sunday, October 25, 2015 - link
There is a hotfix NVMe driver available for Windows 7: https://support.microsoft.com/en-us/kb/2990941blos - Monday, October 26, 2015 - link
I slipstreamed that hotfix (and almost 200 other fixes) using NTLite to a Win7SP1 image, wrote it back to usb, booted and it would still not allow me to install to a 951 NVMe drive... no drives found.Has anybody got this to work?
Windows 10 installs just fine but I have an unused W7 Pro license and I would really like to use it to active a W10 install.
I hear the next version of W10 will activate directly from W7 licenses... but hopefully that'll arrive in time before the W10 will really want the activation. Or perhaps re-arming to extend a bit?

Yes it works but you need to integrate it in boot.wim as well.I made some details here about it, also nothing an errors that MS is still to fix in that KB article.
Even though I reported it a long time ago:

Ah that explains a lot, didn't know that the boot.wim was a different environment :)Quick search indicates that boot.wim integration is already available on the NTLite, so I guess it's playtime for this weekend :)

The test system doesn't have a discrete video card. Would a high-powered video card impact the performance of the M.2 PCIe setup?AnnonymousCoward - Wednesday, October 28, 2015 - link

I've read the review and others and I guess I don't see a reason to get one of these drives yet. Am I missing something? It seems that the real world performance doesn't justify the nearly twice the cost as other Samsung SATA drives. I was really hoping that the rated speeds would translate into actual real world performance, but that doesn't appear to be the case.Tuishimi - Thursday, November 5, 2015 - link
$350... I could live with that. Sounds like a decent piece of hardware.
