The Samsung 850 EVO 4TB SSD Review
by Billy Tallis on July 11, 2016 10:00 AM ESTAnandTech Storage Bench - Heavy
Our Heavy storage benchmark is proportionally more write-heavy than The Destroyer, but much shorter overall. The total writes in the Heavy test aren't enough to fill the drive, so performance never drops down to steady state. This test is far more representative of a power user's day to day usage, and is heavily influenced by the drive's peak performance. The Heavy workload test details can be found here.
The 4TB 850 EVO is slightly faster overall on the Heavy test than the 2TB 850 EVO, so it takes over as the fastest TLC drive. The 1TB and 2TB 850 Pros are only a little faster.
Average service time of the 4TB 850 EVO has regressed somewhat compared to the 1TB and 2TB models, but it still can't be beat by TLC from anybody other than Samsung.
The quantity of latency outliers experienced by the 4TB 850 EVO places it at the bottom of the highest tier of drives and below the 1TB and 2TB models.
The 4TB 850 EVO uses very slightly more power than the 2TB, but both are much more efficient than the 1TB model and score reasonably well given the high capacity.

If you "work" with 4k raw videos you can afford the enterprise level SSD's with their multi petabyte endurance rating.mapesdhs - Wednesday, July 13, 2016 - link
Exactly. I know someone who's been testing 8K editing at a movie company, he was able to get over 8GB/sec from a good Enterprise PCIe device, with consistent performance being absolutely critical. He did try RAIDs of 850 Pros but they just couldn't handle it.AnnonymousCoward - Monday, July 11, 2016 - link
Look at the graph on this page...the Samsung showed bad sectors 4 times earlier than the others: http://techreport.com/review/27909/the-ssd-enduran...3 things matter to me with SSDs: cost, reliability, and UX performance.

That was 2-D TLC. The 850 uses much more robust 3-D NAND.AnnonymousCoward - Tuesday, July 12, 2016 - link
I guess we need updated data then :)ddriver - Monday, July 11, 2016 - link
Well, that's the 840 pro - old stuff... Also, it is possible that samsung have more strict criteria of when a sector becomes unreliable and requires reallocation.Palorim12 - Tuesday, July 12, 2016 - link
But in the end, didn't the 840 Pro outlast all the other drives?hojnikb - Monday, July 11, 2016 - link
That endurance rating is simply for segmentation purposes. In reality, drive should easily reach 4PB+ of writes, before crapping out.mdw9604 - Tuesday, July 12, 2016 - link
Can you explain? I'd like to buy one for a project I am working on, if this is true.mdw9604 - Tuesday, July 12, 2016 - link
I agree. I know its EVO...but write endurance on a drive that expensive is pretty bad.
