    A backup is a file that stores files in case something happens to the device being backed up. like saving a game on pc or console.. Hope it helps!

    I know this is a necrobump, but I came here from Google and am trying to build a home Windows 10 PC, and I want to put in a Ryzen 1600x processor and Vega graphics card. But, I also want fast storage speeds. I've been used to the fast speed of this MacBook Pro in OP's post.

    I have 3 questions.

    1. Is the drive in OP's post and M.2 NVMe drive?
    2. If it is, how fast is it?
    3. Would I be better off using a SATA SSD?
    4. Can you notice the difference in speeds?

    Easy enough, if you search by model number.
    OCZ RVD400-M22280-512G-A
    Samsung 850 EVO 1TB

    The Toshiba/OCZ, in theory, will be 4 to 5x faster than the Samsung, assuming the bus supports it at full speed.
    Will you notice the difference? Depends on how fast you blink :D

    The 2014 had 700Mb/sec read/write speeds, the 2015 doubled that and the 2016 is so fast it maxes out black magic speed test app at its limit.
