Samsung 950 Pro M.2 NVME SSD Review (256/512GB) – The NVMe Effect

THE SSD REVIEW TEST PROTOCOL

At The SSD Review, we test our SSDs slightly different depending upon the drive’s marketed purpose, be it consumer/oem or enterprise focused SSD. For a consumer SSD, our goal is to test in a system that has been optimized with our SSD Optimization Guide, however, CPU C States may or may not have been altered, dependent on motherboard UEFI features. Benchmarks for our consumer tests are that of fresh drives (PCMark 8 testing exempt), so that we can verify that the manufacturer’s specifications match the SSD. Additionally, we also include links to the benchmarks used in our reports so that you as the reader can replicate our tests to confirm that your SSD is top-notch.

TSSDR Z170 TEST BENCH COMPONENTS

Our newest Z170 Test bench was the result of some great sponsorship’s and our appreciation goes to Samsung, Corsair, ASRock, PNY and Intel for helping us with this build. All of the hardware we use for testing is available for purchases at a reasonable price; albeit this specific build is a tad high-end. The links provided below can assist in pricing and availability of the hardware contained within this system:

PC CHASSIS: Corsair 760T White Full Window
MOTHERBOARD: ASRock Z170 Extreme7+ ATX DDR4
CPU: Intel I7-6700K 4.00 GHz
CPU COOLER: Corsair Hydro Series H110i GTX
POWER SUPPLY: Corsair HX1200i ATX12V
GRAPHICS: PNY GTX 980 4GB XLR8 Pro OC
MEMORY: Corsair Dominator Pl 32GB 2800
STORAGE: Intel 750 Series 1.2TB NVMe SSD
KEYBOARD: Corsair Vengeance K70 Mech
MOUSE: Corsair White M65 Laser
OS Microsoft Windows 10 Home 64 Bit

BENCHMARK SOFTWARE

The software used for today’s analysis is typical of many of our reports and consists of ATTO Disk BenchMark, Crystal DiskMark, AS SSD, Anvil Storage UtilitiesPCMark Vantage, PCMark 8 and perhaps even a result or two from IOMeter. Most of this software is FREE and access to all programs can be done by simply clicking on the title of the benchmark. For a complete background and linkage to the software we use, check out our recent article, “The Ultimate Guide To SSD Benchmark Software“.

As we are testing both the 256GB and the 512GB version of the 950 Pro,  our layout will be such that we will provide our benchmark results in a side by side fashion, for the most part.

ATTO DISK BENCHMARK VER. 2.47

ATTO Disk Benchmark is a relatively easy-to-use benchmark tool, which happens to be the benchmark of choice for many manufacturers. ATTO uses compressible data rather than random data, which results in higher performance and thus, higher benchmark scores. In our testing, we have selected the transfer size to range from 0.5KB to 8192KB, and have set the total length of the test to be 256MB.

Samsung SSD 950 Pro 256GB M2 ATTO RST Driver

Samsung 950 Pro NVMe 512GB SSD ATTO Benchmark

Both ATTO results match listed specifications, the 256GB attaining 2.2GB/s read and 957MB/s write with the 512GB capacity reaching 2.5GB/s read and 1.5GB/s write. Although we see a bit of a drop in the larger data samples, we can tell by the speed progression with increased data samples that these SSDs are solid.

curious if on the ASUS Z170 Deluxe if you use the M.2 port and the PCIe card that come with the board if you can raid 0 two 512 GB 950 Pros together and boot form that drive.

From what I remember from the manual, yes you can.

Les. How are you s e curing the M.2 to the motherboard.
I see the screw but ASRock doesnt provide the holes for the screw.
Are you customizing this yourself?
I need the PCI e 1X slot so before I even try to secure this I just wanted to hear how you are doing this.

Thanks

No I dont believe you can unless that board, like the ASRock Extreme 7+ Z170, has Intel RST built right into the BIOS to accomodate for that boot; I believe only ASRock has tackled this but might be wrong. That is what makes this board so special.

can you check and reply it should be able to the Asus deluxe boot? as it has NVME boot support

Les@TheSSDReview
Guest

It has NVMe support for a drive in the M2 slot, not a RAID configuration. For the NVMe setup you are speaking of to be bootable, it needs to be tackled as a RAID boot at the UEFI level. I may be wrong but believe only ASRock has tackled this by including SRT in their UFI. I am using that right now.

how did you configure you bios on the Asrock deluxe to boot from this M2 slot ? Are you using WIN 10?
Any lessons learned to get it to recognize ? Thank you for your time

Les@TheSSDReview
Guest

There is no configuration necessary; simply plug it in and install your OS. It should be recognized immediately. Are you using this board? If so, read the manual to understand that one needs to match the right storage with the right slot. For instance, the first M1 slot is tied into the first 2 Intel SATA 3 slots (0/1) and both cannot be used simultaneously UNLESS you configure the M.2 to bypass that through the UEFI.

Would it run on a x99 deluxe 3.1???

No way to make this work on x99 deluxe. Recognized one time after 5 reboots…installed with brackets, everything tried. Never seen in BIOS, seen twice in the OS, installed driver and at random disappears freezeng the system. Latest 1901 bios

i m going to return this and buying a cheaper 850 pro

Why anyone still jumps at those boards amazes me. I have heard heartache after heartache with respect to that company and M2 SSDs. ASRock…plug and play…simple as that. Right now I am playing with and testing 3 NVMe drives as a boot device in the ASRock Extreme 7. You cannot do this with any other board in the world. Meanwhile, people frustrate themselves trying to get one drive working with ‘those boards’.

Hi i have right now a 950 pro windows 10 and a 951 ahci windows 8,1running on my x99 a asus board and it works great

Well, I am running one 950 Pro on my ASUS Z170 Deluxe right now under Windows 10. Performance is amazing, setup was easy — no need to touch anything in the UEFI for me. I’m about to add a second 950 Pro in RAID 0 and jump to ludicrous speed. I’ll post a follow up when it is done.

It was slightly tricky to set up, but I’m running strong now. Sequential benchmark reads are 3GB/s+, and Sequential writes are the same at high queue depths and ~1.5GB/s at lower queue depths. I believe some of these speeds are capped by the PCI 4x interface.

Les explain how you are securing the M.2,
I see the screw but do not see a receptacle on any ASRock or Supermicro board I own.
Just curious how you secure it on the PCB…

I believe some of Gigabyte’s Z170 boards have two M.2 slots onboard (e.g., GA-Z170X-UD3). From what I read in the manuals, these slots can be set up in RAID mode. But I need to double check.

1 x M.2 Socket 3 for M Key Type 2280

thanks!

This thing is so awesome I am going to need to get a computer to put one in! I currently have an iMac so no way I am going to mess with that.

Atto disk benchmark performance drop: throttling?

Les@TheSSDReview

No… I considered this and it would occur elsewhere if that were the case, especially in PCMark 8 testing.

Does Samsung supply Windows 7 drivers for this? I had a Intel 750 with the Intel drivers working ok in Windows 7 as my boot drive. Had to dump it though because it took Intel way to long to release a updated firmware to fix performance issues.

Les@TheSSDReview
Guest

They only supply the NVMe driver as discussed and we cannot answer as to whether that is Win 7 compatible or not. Question is submitted though.

Thank you, look forward to hearing an update on comparability with win 7.

I see name drivers that only install from a exe but I need stand alone driver to make it bootable with win 7. Don’t want to order one till its confirmed

is it going to work well any laptop with this spec: M type, M.2 sata, 80mm?

Les@TheSSDReview
Guest

No it will not. This is a NVMe SSD and not AHCI so getting it to work on older chipsets where NVMe is not integrated may be tricky. As well, because NVMe is so new, things can get a little tricky from one situation to another.

To clarify, this is not a plug and play upgrade for older systems that may have used M2 AHCI SSDs.
