The Samsung 960 EVO (1TB) Review
by Billy Tallis on November 15, 2016 10:00 AM ESTMixed Random Read/Write Performance
The mixed random I/O benchmark starts with a pure read test and gradually increases the proportion of writes, finishing with pure writes. The queue depth is 3 for the entire test and each subtest lasts for 3 minutes, for a total test duration of 18 minutes. As with the pure random write test, this test is restricted to a 16GB span of the drive, which is empty save for the 16GB test file.
The 960 EVO is essentially tied for second place with the OCZ RD400 and significantly behind the 960 Pro in overall performance on mixed random I/O.
The 960 EVO's power efficiency on this test is not great, but it is a big improvement over last year's 950 Pro.

The 960 EVO's high performance score comes primarily from its great performance in the pure write final phase of the test. Throughout the rest of the test, the 960 EVO is not as fast as the 950 Pro.
Mixed Sequential Read/Write Performance
The mixed sequential access test covers the entire span of the drive and uses a queue depth of one. It starts with a pure read test and gradually increases the proportion of writes, finishing with pure writes. Each subtest lasts for 3 minutes, for a total test duration of 18 minutes. The drive is filled before the test starts.
The 960 EVO's mixed sequential I/O performance is the second-fastest among M.2 SSDs and third place overall. Performance is modestly improved over the 950 Pro.
The 960 EVO's power efficiency is better than most PCIe SSDs, but still well behind the 960 Pro.

The 960 EVO's performance in the pure read first phase of the test is great, but its performance with an 80/20 mix is much worse than the 950 Pro or OCZ RD400. The worst-case performance is also not as good as the RD400 or 960 Pro.

Vaporware. 'Nuff said.Magichands8 - Tuesday, November 15, 2016 - link
This is magnificent! Not only has Samsung produced an SSD that under performs its own previous generation product but one that manages to do so while using even MORE power at an even HIGHER price per GB! They even put it on a form factor that makes the drive almost entirely irrelevant! The only thing missing is a feature that makes the modules randomly explode upon contact with the users computer.Dug - Tuesday, November 15, 2016 - link
What are you talking about?BrokenCrayons - Tuesday, November 15, 2016 - link
You have a unique perspective. :)Daggoth - Tuesday, November 15, 2016 - link
I have a question, isn't the z97 chipset capped at 2GB per second due to DMI 2.0? Isn't this a problem for the max sequential reads?Billy Tallis - Tuesday, November 15, 2016 - link
I test PCIe SSDs in the primary PCIe 3.0 x16 slot, because the riser card used for power measurement is a 16-lane low-profile card.Bullwinkle J Moose - Tuesday, November 15, 2016 - link
The 960 Pro is much better price over the duration of WarrantyI can generally kill 1 out of 4 SSD's within the warranty period
so if I buy 4 960 Pro's and 4-960 EVO's, here is the breakdown @ 500GB
4-960 Pro's = $330 X 4 or $1320 divided by 5yr warranty = $264 per year for 5 years
or
4-960 EVO's = $250 X 4 or $1000 divided by 3 years = $333.33 per year for 3 years
per year cost under warranty is WAY better for the PRO!
3 year warranty with TLC just doesn't do it for me

I would REALLY need to be trying to kill at least 1 out of 4 but I could prolly do itSo tell me more about the internal speed Billy.....
How many seconds does it take to copy and paste 100GB to and from the same 960EVO?
and from the 960PRO?

Why wasn't the 256gb version tested? Tom reviewed it and it was kinda meh compared to the rest of the mlc drives, it was as bad as the 600p in some cases.Billy Tallis - Tuesday, November 15, 2016 - link
The 250GB was tested. It died. See page 1 for details.
