The Samsung 850 EVO 4TB SSD Review
by Billy Tallis on July 11, 2016 10:00 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 4TB 850 EVO is in a four-way tie for highest average data rate, and the Samsung drives in general score very well and quite close to the SATA interface limits.
The 4TB 850 EVO's average service time is not top notch, but is still reasonable for a high-end SATA drive.
Once again the latency of the 4TB isn't the best and isn't quite as good as the 1TB and 2TB counterparts, but it's still better than all the other TLC drives.
The power usage of the 4TB EVO is a bit worse than the 2TB model when fresh but is slightly better for a full drive, showing that this drive isn't worth having if you're barely going to use it.

Was always interested in a higher capacity M.2 drive for my XPS13. 850 Evo maxed out at 512GB where as the Sandisk X400 was the only reliable one at 1TB.Amazon has just listed a 850 Evo 1TB M.2 @ 350 USD - So eagerly waiting for an update from Anand in this regards :)

Though SATA interface is limiting the performance of such drives, isnt Random performance has more room to grow?hMunster - Saturday, July 16, 2016 - link
The write endurance is really shit at only 75 writes. How large are the pages, and how much is typical write amplification, or is that already factored in?NomadXL - Wednesday, July 27, 2016 - link
So this new 850 EVO 4TB has a 300 Endurance.. and the previous one of 2TB aswell?I thought the 2TB model had only a 150TB endurance rating..
Please can somebody confirm this?
