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.

At CES Mushkin said they were planning on releasing a 4TB SSD by the end of the year. They are targeting a $500 price point. Unless they scrapped it, this could be a cheaper option before the end of the year.http://techreport.com/news/29583/mushkin-previews-...

It was a misinterpretation. The $500 price point was for the 2TB drive, with the price of the 4TB being unannounced (likely a double at least).http://www.anandtech.com/comments/9986/ces-2016-ro...

I should of figured it was to good to be true. Still a competing $1000 drive could convince Samsung to lower their price. Assuming the speed is comparable between the two.aggiechase37 - Monday, July 11, 2016 - link
Way WAY WAAAAYYY too expensive. For this price you could get piece together a RAID configuration out of regular HDD and get a decent amount of the same performance AND the added bonus of having redundancy in the case of a drive failure. Can't see who purchases this.Chloiber - Monday, July 11, 2016 - link
Not sure why anyone would want to buy this when you can get a 4TB Samsung P863 Enterprise SSD for 300$ more...Taracta - Monday, July 11, 2016 - link
Isn't the 25% over-provisioning getting a bit much for these larger SSDs? Does a 4TB SSD really need 1TB over-provisioning to max-out relative performance? Would 10% be enough for these large drives?Billy Tallis - Monday, July 11, 2016 - link
That is something I've wondered about and will probably look in to eventually, but it would be pretty time consuming to test and isn't something I can see adding to the routine suite of benchmarks.Impulses - Monday, July 11, 2016 - link
Something to ask Samsung tho?Taracta - Thursday, July 14, 2016 - link
Thanks for your reply. I believe that you should just test this 4TB SSD for now to see the impact and another couple of different ~4TB SSDs when available to compare with these results. Forget about the lesser drives, too many and too late.ACE76 - Monday, July 11, 2016 - link
hopefully we see more manufacturers release 4tb and greater SSDs...these drives will end the need for platter based hard drives for good...price is too high right now but it should come down over the next 6 months to a year.
