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.

But you could buy 8TB of MLC-based Mushkin Reactor for the price of 4TB of 850 EVO. Then you consider a RAID of Reactors will be 4x the sequential performance of a 850 EVO.And let's face it, with a storage drive like a 4TB SSD, sequential performance is all that really matters unless you actually plan to use it as a boot/system drive.

http://www.fudzilla.com/news/memory/39668-mushkin-...I can't wait for this...at $500 for 4tb, I'd move all my media over to SSDs in a RAID 10 array.

We got clarification from Mushkin at the time when we posted similar: the $500 price point was actually a mischaracterization. The initial price would be much closer to $1000, with $500 being a goal nearer EOL.Oxford Guy - Monday, July 11, 2016 - link
How does TRIM fit into the picture of RAIDed ssds, though?Impulses - Tuesday, July 12, 2016 - link
TRIM has been working on RAID for a while, years actually, at least on Intel's newer chipsets... They kept it from older chipsets (like my old rig's P67) but enterprising users back ported it thru BIOS edits/hacks.Impulses - Tuesday, July 12, 2016 - link
Not that I'm against the EVOs, running 2x 1TB in RAID myself.bittermann - Monday, July 11, 2016 - link
Good luck fitting 4TB of data on that 1TB drive....Spoogie - Monday, July 11, 2016 - link
With Optane on the horizon, no reason to bite at this price point.Flunk - Monday, July 11, 2016 - link
I don't think it's the same market. Optane isn't going to be less than $1 a GB at the start.patrickjp93 - Monday, July 11, 2016 - link
65 cents/GB actually.
