The M.2 NVMe drives like the Samsung 960 EVO is PCIe 3.0 x 4 speed. It's read/write speed will blow the door off any SATA based drives.
True. But at the same time a lie.
True: Working with large files, moving large files to other NVMe drives and overall very heavy workloads it will outperform any sata drive by big margins.
Lie: For the general consumer with the general workload they put on the computer like games, windows boot up time, open a web browser, multi-task between 3 - 5 programs, watching movies, sort through songs, etc etc etc.
Generally light to light moderate workload the M.2 NVMe drive will not outperform a good Sata SSD by alot.
The 4K Q1 - 4 IOPS is almost identical.
Like I sayd, I have both and tryed just to see if I could really see a difference. And without a stop watch you really could not tell the difference at all besides in a very few situations.
So... Is the M.2 NVMe 960evo fast?
If you do the kind of work that needs its speed and can take advantage of it. Heck yea very mutch so.
But for the avg. consumer out there, the answer is no. It is not mutch faster than any other Sata SSD, just by a tiny little bit and not worth the price premium.
If you got the choice between a 500GB 960evo or 1TB 850pro... I would take the 850pro any day UNTIL that is, the computer programs, games, etc will start to really take advantage of the NVMe. Until then I will not buy a new one cause I dont use the computer in a way that can take advantage of the speeds.
Its like having a car that you know on the paper can do 200+ mph, but you never ever take it to a air strip or a racing track. Hence you are bound by speed limits.
I know my 960evo on paper and benchmarks are fast, but with the programs and games I use I put a speed limit on it in a way.
Edit: Or to put in a way most people can understand. Its like getting a GTX 1080Ti and only play games like tetris on it.... overkill...
