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.

6GB? My first hard drive was 200MB!bug77 - Tuesday, July 12, 2016 - link
Yeah, if you can get one of these at half the MSRP, it's only $750 :rolleyes:Flunk - Monday, July 11, 2016 - link
It's only $0.36 a GB, that's pretty cheap.patrickjp93 - Monday, July 11, 2016 - link
You can get something like the Sandisk Ultra II 1TB for 21 cents/GB.ddriver - Monday, July 11, 2016 - link
But then again why would you? Unless you are starving, and if you are, then you wouldn't be buying SSDs...I can't honestly think of any good reason to buy something other than samsung SSD - they have the most warranty and performance is top notch too, reliability seems to be better too.

Support and spec compliance. Samsung *still* ship firmware that claims support for queued TRIM ATA commands, but erases data if they're actually used. The consistent response is "Windows doesn't use these commands, we don't support other OS's", never mind that it's part of the SATA spec.(no, the kernel bug they fixed is completely unrelated)
I *hate* manufacturers treating "works in current Windows" as an acceptable spec - it's guaranteed to shoot you in the foot down the line, as everyone saw with Vista. So I bought a SanDisk instead.

To clarify, I mean the way Vista broke all the manufacturers' stupid assumptions based on XP's behaviour.Also, the months it took for them to bodge around the performance degradation.

Acutally, I hate to back up Microsoft, but they DID say it was a complete re-write of Windows, and that it would not be the same OS at all.It performed horribly with low amounts of RAM, and at the time, the big RAM makers were in collusion over RAM price fixing (look it up), so that is why we saw laptops, with Vista being shipped with 256MB of RAM, which was a mess, I agree.
But someone like myself, who had way more RAM than that, found it to be just fine. And it was way less infected than XP too.
I guess your printer never received a Vista driver then? Too bad.
But for me, and other client workstations with reasonable amounts of installed RAM I oversaw, it worked just fine, from the first day I used it.
Flame away...

Except they lied. Go onto your desktop and try to make a folder called "con". You can't, even on Windows 10, because they are still using code from Windows for Workgroups.There are a few others that (PRN, AUX, NUL, COM1...), which are all legacy Windows device names. They never '"rewrote" anything from the ground up.

Oy vey, muh geschafts can`t go into appropriate folders now!Such shoah.
