The Samsung 750 EVO (120GB & 250GB) SSD Review: A Return To Planar NAND
by Billy Tallis on April 22, 2016 8:00 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 Heavy test doesn't write enough data to fill a 120GB drive, and when there's still spare area the 750 EVO performs better than any other planar TLC drive. When the test is run on a full drive the 750 EVO suffers more than most and falls to the bottom of the rankings.
The penalty that the 750 EVO pays when filled is even more apparent when looking at average service times, pushing it into last place.
Even when starting on an empty drive, the 750 EVO's latency outlier situation isn't great, beating the ADATA SP550 but little else.
The energy usage of the 750 EVO only stands out for the full drive case. When starting with an empty drive, the 750 EVO uses less energy overall than the other planar TLC drives.

I apologize for being rude but that's just not what they are made for. Paying 1,000$ for a 2tb NVME SSD just for cold storage is a lot like buying a 500,000$ super-car just to drop your kids off at school....Bleakwise - Sunday, April 24, 2016 - link
More like even up to 8k.A mechanical hard drive will roll out 150-200 GigaBYTES per second sequential read. 4k video is like 5 megaBYTES per second max. 8k would be 20, 16k would be 80. This is on h264, h265 will cut these in half, so you could watch a 32k video on something like a WD black.
I suppose if you wanted to play back something in 64k resolution you'd need an SSD though, at least until CPU/GPU tech makes h266 or h267 codec or whatever available.

To be clear. The only reason content creators need NVME drives for 4k is because they work in uncompressed or intermediate formats. They need NVME drives for the same reason that a 4k bitmap is like 22 megabytes while the JPEG is just one or two.Eden-K121D - Sunday, April 24, 2016 - link
I think You meant MegaBYTES otherwise your hypothetical disk would be faster than anything on this planet LOLslowdemon21 - Friday, April 29, 2016 - link

Between the OS and software, my Windows desktop is currently using about 110GB of a 250GB hard drive. I don't game much, but there are handful of titles loaded on that system and I haven't exactly been working very hard at keeping my drive clean.On my primary computer (the desktop is more a network appliance than a day-to-day workstation as it runs headless now thanks to a combination of Steam in home streaming and VNC), a laptop with a 60GB SSD, there's about 35GB of free storage capacity, but the OS footprint is a lot smaller since it's a Linux box.
Granted, games are getting larger and a few newer titles I'm likely to play in the next year or so will make it necessary to start looking at more storage, but 250GB seems perfectly reasonable right now.

Yeah just running 80GB of the 250GB 850EVO in my workstation. Having masses of software and data hanging around on a mchine seem crazy to me. Each to their own. However, most customers I see struggle to go over 60-70GB.bji - Friday, April 22, 2016 - link
This is because you guys don't pirate tons of movies and hoard them on SSD drives like some people who then complain about the cost of the media they use to store their pirated goods. I don't either, which is why the 250 GB SSD in my macbook pro is still only half full after nearly 4 years of use.bji - Friday, April 22, 2016 - link
BTW complaining about the cost of storage for pirated goods is like the ultimate douchebaggery imagineable. Not only are you ripping off people who worked to create the content you've pirated, you want to complain about how much money you have to pay to companies to produce the storage that you need to store it.StrangerGuy - Friday, April 22, 2016 - link
That's not ultimate pirate douchebaggery, it would be complaining why pirated videos are no longer available in Xvid because everybody should cater to people with decade old DVD players.
