    I’ve always read that you can do 100% of the capacity as “surge” (I haven’t read a definition, but I think it’s no more than 3-5 seconds) and 80% the rest of the time.

    So your clothes dryer can start the heating element and turn on the motor at the same time and use the whole 30 amp outlet it’s plugged into if it wants to because the power will go down once the drum is up to speed. From there, the power might go down further once it’s up to temperature. If you’re charging your car on that same outlet, though, it needs to be limited to 24 amps because it’ll be using that the whole time.

    It gets weird, though, with 15/20 amp, though. Technically, if it’s a 15amp outlet, you should only use 12 amps continuously. However, a lot of the time everything except the outlet is specced for 20amps. In that situation, you should still follow the same rules, but it’s more forgiving.

    It’s up to you. Things to consider:

    • Size of data
    • Recovery speed (Internet speed)
    • Recovery time objective
    • Recovery point objective (If you’re backing up once per day, is it okay to lose 23 hours of data when a disk fails?)

    If your recovery objectives can be met with the anticipated data size and recovery speed, then you could do RAID 0 instead of RAID 1 to get higher speeds and capacity. Just know that if you do that, you better be on top of your backups because they will be needed eventually.
