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.

Too Expensive. $999 would have been a sweet spot and a potential option for meZak - Monday, July 11, 2016 - link
The price will come down. Eventually.Ratman6161 - Monday, July 11, 2016 - link
Doesn't really mater if the price goes down, its still a niche product. The EVO's are great general purpose desktop drives. But the people who need a general purpose desktop drive, mostly don't need 4TB and would not buy one at $500 let alone at $1500. In my case, I've got a 250GB Evo and a 1 TB spinning disk for storage of music, pictures, video etc. So I guess a cheap enough 2 TB SSD could work for me just because it would be marginally easier to not have two separate chunks of storage to deal with...but thats just a marginal increase in convienience. The stuff I have on a spinning disk doesn't really need the performance of an SSD anyway.I know, now someone will jump in with "well I sure need that 4 TB" but I still say that isn't the norm. I really don't believe they will sell very many of these compared to the 1 TB and below even if the price comes down.

I don't need it. But it's exciting to see this progress in SSDs. It'll take a while but mass production will bring the price/size ratio down.Impulses - Monday, July 11, 2016 - link
OTOH lack of competition will probably counter that to an extent... But I'm glad it exists too, if nothing else it might mean more sales on the 2TB. :pleexgx - Sunday, August 7, 2016 - link
was so funny when i clicked on 25% OP, but really the extra OP is really only needed for places where your writing constantly as normally the drive is Trimmed (most SSD/HDDs life is read then write, unless in a server setup that does lots of writes) the drives normal hidden OP is what 400-500MB ?beginner99 - Tuesday, July 12, 2016 - link
Agree. This shows that HDDs are here to stay for another decade. The same for 4 TB in form of a HDD can be had for about $130. So that 1/10th of the SSD price and as you said for media files, you don't need an SSD at all.Impulses - Wednesday, July 13, 2016 - link
Another decade? That seems like a stretch unless you're hoarding BD tips and the like... A decade ago we didn't even have SSDs.joex4444 - Tuesday, July 19, 2016 - link
If you have 4TB of stuff to store and it's mostly media that is accessed infrequently, it would only make sense to buy a 4TB SSD over a 4TB HDD if the prices are comparable. We've technically had SSDs for decades, it's just that they used to be in the millions of dollars per drive rather than $100 or so. Exactly how production will change to make 4TB drives cheaper isn't clear. It could be that we've already reached the lowest price per GB and all that remains is to have that scale linearly. This would mean that if 250GB drives cost $60, then a 4TB drive should cost 16 times that, or $960. Maybe some kind of discount could bring it into the $750 range, but in order to get down to $130 we need significant changes. That would put a 250GB drive on the order of $25.JimmiG - Wednesday, July 13, 2016 - link
Of course it's not "needed" right now, but it's nice to see progress. The 6 GB HDD I used in my Pentium system was plenty at the time - I didn't "need" those fancy new 20 GB drives...
