Samsung 950 PRO M.2 SSD review





In this review we test the new M.2 super fast Samsung 950 PRO Series M.2 SSDs. These new M.2 units use the nvm express (NVME) protocol and that means storage technology at hyper fast speeds while remaining competitive in pricing. Samsung will shock and awe you with these puppies.

This would've been awesome for Surface Pro 4 instead of the cheaper version!!

would be great if you had actual real world performance comparisons of actual OS load times, game load times and application load times compared between various SSDs. as it stands now this arbitrary MB/s number (referring to page 9 of review) based on some simulated game/program load isn't very useful to end user (seems like it's more useful for company selling SSD because their product appears better, just like all those synthetic tests).
I've seen some other reviews where they compare load times in actual games, programs and OS and there is no meaningful difference between 950Pro and something like 850 EVO.
Agree, at least ffxiv-heavensward-bench if you are lazy. It does show load time seconds also.

Hilbert, it's not necessary to disable automatic defrag in modern Windows OS (at least in 8 and newer). It will not defrag SSD's. It will just run trim.

Holy megabytes! That thing is fast! Great review also boss.
Btw a small fact. I actually bought a Samsung 951 NVME M.2 256GB, but afterwards cancelled it and replaced it with a 850 EVO 500GB M.2 for the same price.
I just couldn't justify not getting the 500GB over the 951 256GB even its 3-4x faster. I do wish I had gotten it tho.
Also my Sammy 850 EVO has something to say to that PCIE SSD. I know, I know. But hey, thats what the test says. lol!

Please disable your rapid cache and actually test the physical NAND of your SSD. You are displaying the results of your system RAM cache.

Why cant Samsung use a heat sink to cool the IO chip ? So that thermal throttling can be avoided even during intense loads.

/jk boss. I do have RAPID Mode enable. I just posted the screenie for fun.
Btw, I will for sure get one of these PCIE SSD in the future.
P.S: I found a AS SSD test I did when I got it.

I wish I had canceled the purchase of my Samsung 951 NVME M.2 256GB as well ... I bought it very very early when there was just a single review of it on the internet and that said nothing about installing windows 7 on it ... which btw , is not possible by any normal means.
I was forced to install windows 10 to use it ... I hate it(win 10) ... I despise it ... I wish to inflict viscious bodily harm to it T_T"
The performance is all there and its ridiculously fast ... but ... again ... windows 10 (tear falls down his cheek) ...
PS: I also hate Samsung for not having proper drivers of it or support in any if its software ... so what if its OEM ? ... if its readily and easily avaible to regular consumers they should have made the extra effort, otherwise made sure regular people could not buy it T_T" ... Samung has fallen badly in my eyes with this.

I can't believe they didn't ship a 1TB variant. I have a 840 500GB now -- and I definitely want the extra speed, but I also want at least 1TB. Meh

I'm guessing the form factor spec doesn't allow for that much height, especially laptops that will also use these. That said, there shouldn't be any reason why people can't add it themselves if their board layout allows.

Samsung announced it when they announced the 48 layer V-NAND. I just wish it was out sooner. So many games, so little space.

working well
heat has not been an issue

My prior über workstation was the Z9PED8 WS and unfortunately it can't do NVMe or m.2 with 4x lanes,
Now Im running a Z10PE-D8 WS
for compatibility and speed the xp941 is very fast and as is the sm951
in order of speed (high to higher) it's xp941, sm951 ahci, sm951 nvme, 950pro nvme.
in order of heat generated (warm to warmer) it's xp941, 950pro nvme, sm951 name, sm951 ahci
I describe the heat from the drives as warm. Under load all chips are less than 49c on all models.
Having 4 titan x sc right above them may increase the environment heat, but its still with normal parameters.
If you look closely at the picture you'll see that I have heatsinks on many motherboard components as well.
There was a company this summer that did a review of the z10 and took a thermal image of the board, so when I saw the review I used the picture as guide to get rid of hot spots
in addition the 950pro only has chips on the top surface which aids in cooling and allows for all those little aluminum heatsinks.
The hottest thing on the whole board now is the chipset controller the c612, and that runs about 104F to about 109F and that sits directly under 2.5 out of 4 video cards.
I can't imagine the drives on motherboard being a heat issue, maybe, but I don't know it might be a heat issue in a tight enclosed environment like a surface or tablet laptop
All temps are so farrrr below spec I'm not concerned

Best benchmark app, overall?
Below are my results: Samsung 850, mSATA, 1 terabyte drive.
Not really a fair result, because I did it in the middle of the day's work, web browsing. Just turned off the background tasks, and ran the test.
Hardware DELL XPS-15, L521-X, 16 GB DDR3. Nvidia 640m. Terabyte SSD +Terabyte HDD, which might be replaced with a multi-terabyte 2.5 inch SSD, to increase speeds, save battery life, heat production and noise.
Used the 64bit version, not the 32 bit. Also the latest version. Does this matter?
With so many benchtest apps, which is the best for the home user, web-browsing, home-backups, etc?

Is the 950 compatible with Asus Maximus Hero VII guys?? Does it use its maximum speed or there is a hold-back from the mobo's side? I just want to use as a data drive.. unrar, installing games, loading games as fast it can and things like that. As a bootable drive I use my 850 PRO. Thanks!

Excellent. I was going to comment that it appeared to me from the Magician screen shot posted that you had turned rapid mode off--very good. I have an 850 EVO, 8 gigs system ram installed, and when I enable rapid mode under Win10x64 my non-paged ram pool jumps from ~200mbs to 1.2GBs. (If I had 16GBs or more installed, I wonder if it would reserve an even larger cache...!) So of course I keep rapid mode turned off as it is likely to hurt more than help, especially in systems of 8GBs or less.
Yes, you're right...excellent performance for this drive! Especially for the size...! Thanks for the review!

Would not be slim. Now what you could do, is kind of make shift a heat spreader from a memory module maybe.
950 Sata III needs to come now! Got an i5 4690 and more memory for my Alpha, just waiting on the 950 to be released in Sata III!
