The Samsung 750 EVO (120GB & 250GB) SSD Review: A Return To Planar NAND
by Billy Tallis on April 22, 2016 8:00 AM ESTAnandTech Storage Bench - Light
Our Light storage test has relatively more sequential accesses and lower queue depths than The Destroyer or the Heavy test, and it's by far the shortest test overall. It's based largely on applications that aren't highly dependent on storage performance, so this is a test more of application launch times and file load times. This test can be seen as the sum of all the little delays in daily usage, but with the idle times trimmed to 25ms it takes less than half an hour to run. Details of the Light test can be found here.
The average data rate scores of the 750 EVOs allow it to blend in to the crowd as a solid performer and the fastest planar TLC drive on the Light test.
The average service time of the 750 EVO again places it as one of the fastest planar TLC drives and a reasonable performer compared to the SATA market overall. The 120GB 750 EVO is also relatively close to the 250GB version, while other 120GB models are considerably slower than their larger counterparts.
The number of latency outliers experienced by the 750 EVO in the Light test is normal for TLC drives but considerably higher than most MLC drives.
Power usage over the course of the Light test separates the drives pretty cleanly into different categories. The 750 EVO clearly requires more power than the 850 EVO, and all the other TLC drives require more power than the 750 EVO. The MLC drives all require less energy than all the TLC drives, except that the 850 Pro sacrifices efficiency to deliver its high performance.

SATA is not yesterdays tech.abrowne1993 - Friday, April 22, 2016 - link

So, everyone with perfectly capable CPUs that are barely slower than current tech should upgrade because SATA is old? I'm not disputing that SATA is the older tech, I'm just looking for a more nuanced and realistic view here. If your workload is sufficiently dependant on IO throughput, by all means get those NVMe drives. But implying that a SATA3 device like a 850pro is not going to do the job for a lot of people.... I have a Z87 4770k running at 4.5GHz. I'm not going to upgrade just for the convenience of M.2 PCIe NVMe support. And I won't do so until 6+ core CPUs with comparable IPC and OC abilities get decently priced.Meteor2 - Saturday, April 23, 2016 - link
No, not at all, and no-one said SATA is inadequate. But it is part of the past, just like 486s and dial-up modems.Bleakwise - Sunday, April 24, 2016 - link
No, SATA has a place. You realize a 2.5 SATA drive has about 10x-20x the volume of a NVME drive. No reason you could n't have a 3.5 inch SATA SSD either.Thus SATA will always be the go-to for high volume storage. Flash memory isn't going to be shrunk down anytime soon either, it degrades both performance and reliability, so until we get something better than flash SATA is going to be the only place you can get something like a 4TB or 8TB SSD.

Shinking thing smaller and smaller is also more expensive, and like I said in terms of flash it also degrades performance. It's much cheaper to build a big-fast thing than a small-fast thing.There is also the issue of RAID and mechanical drives for mass storage. I can setup a 20TB fakeraid with an SSD write-back cache for under a thousand dollars. Hardware raid would be about 2000$. The NVME version would be about 8000$ to 10000$.

There are 2.5" NVMe drives using the U.2 connector to provide the same 4 lanes of PCIe that can be supplied by the M.2 connector.slowdemon21 - Friday, April 29, 2016 - link
Agree. SATA is the skylake bottleneckewitte - Tuesday, May 24, 2016 - link
I hacked my bios to run a 950 pro in a z87 it was ridiculous to spend so much upgrading from a 4790k.Coup27 - Friday, April 22, 2016 - link
Do you not think there is something wrong with the phrase "consumer grade NVMe 2TB+ SSD" ?You could also RAID some SATA 2TB SSD's to give you want you need. I doubt you "really" need all of that space on NVMe, so maybe a 256 or 512GB 950 Pro + some 850 EVO's in RAID would work well, and is available now.
