Introduction, Specifications and Packaging
The ‘budget’ EVO line gets a speed boost!
Since Samsung’s announcement of the 960 Series SSDs, I have been patiently waiting not for the 960 PRO (reviewed a few weeks back), but for the 960 EVO. It is the EVO, in my opinion, that is the big release here. Sure, it doesn’t have the quad Hexadecimal Die Packages, Package-on-Package DRAM and ultimate higher capacity of the PRO, but what it *does* potentially have is class leading performance / price in the M.2 form factor. Just as we all wanted lower cost SSDs in the 2.5” SATA form factor, M.2 is seeing greater adoption across laptops and desktop motherboards, and it’s high time we started seeing M.2 SSDs come down in price.
I know, don’t tell me, the Intel 600p carries a SATA-level cost/GB in an M.2 form factor. Sure that’s great, and while I do recommend that SSD for those on a budget, its caching scheme comes with some particularly nasty inconsistencies in sustained writes that may scare off some power users. Samsung 840/850 EVO SSDs have historically handled the transitions between SLC cache and TLC bulk writes far better than any competing units, and I’ve eagerly anticipated the chance to see how well their implementation carries over to an NVMe SSD. Fortunately for us, that day is today:
An important point to note in the performance specs – the lowest capacity model is the only one to see its performance significantly taper in stated specifications. That is because even with its 48-layer VNAND operating in SLC mode, there are only two packages on all 960 EVOs and the 250GB capacity comes equipped with the fewest dies to spread the work across. Less parallelism leads to lower ultimate performance. Still, it is impressive to see only 250GB of flash reaching near saturation of PCIe 3.0 x4 in reads.
I've appended the 'sustained' (TLC) performance specs at the bottom of the above chart. These 'after TurboWrite' figures are the expected performance after the SLC cache has been depleted. This is nearly impossible in actual usage scenarios, as it is extremely difficult for any typical (or even power user) desktop workloads to write fast and long enough to deplete such a cache, especially considering how much larger these caches are compared to prior models.
Samsung has carried forward their simple packaging introduced with the 960 PRO. The felt pad on the bottom of the installation guide is both functional and elegant, keeping the 960 Pro safely in place during shipment.
Hmm, maybe add 850 evo raid
Hmm, maybe add 850 evo raid into the chart? Obviously testing every single drive in raid takes way too long, but raid 850 evo or raid of a budget drive seems like an interesting data point that doesn’t take way too long.
As tempting as it may be I
As tempting as it may be I cannot find myself ever buying a TLC drive for anything other than a scratch drive, cache drive etc.
Why? Because of the lifespan

As an AMD owner, I’d love to see benchmarks of this on a motherboard with a PCIe 2.0 4x m.2 connector (like the Gigabyte 990fx-gamer). Does it completely saturate the 20Gb/s bandwidth?
Wow, poor showing in the
Wow, poor showing in the Intel 600p. I feel bad for those who upgraded to the Intel drive on the assumption NVME would be a big boost over a SATA6GB SSD.
The Client QD weighted chart makes it look like it might actually be worth upgrading from a SATA to NVME SSD for real world performance.
I’m curious where the OEM LiteON SSD in my Dell laptop would fit into the mix.
Awesome review. Really like
Awesome review. Really like the detailed info about the topic. I would love to ask one thing about these drives. Will I gain any performance boost by moving from X79 (DMI 1) to Z170 (DMI 3) ?
question about endurance or
question about endurance or TBW ssd 960 evo 250gb.
it’s said 100 TBW but is it true
for for example i have ssd mx300 and according to crucial software
and other software like crstal disk the total write is 500000gb and life of the ssd around 15%, in the website of crucial the TBW of the ssd 160 TBW so it clean way above that.
i am interesting in buying the SSD 960 evo 250GB SO MY QUESTION IS :
WHAT IS THE REAL TWB OF THE SSD 960 EVO or the max write of the ssd until it die ?
