Will copying files from one external drive to another create write tasks for my machine internal drive? how does that work?

Quills@sh.itjust.works to Asklemmy@lemmy.ml – 34 points –

So, i use linux with kde and was copying some gigabytes of files from a smartphone to a usb device and while doing that the system monitor kept showing that it was writing some mb/s and i got curious, is said writing happening to my ssd or is it just talking about the usb drive?

The data should be bypassing your internal disk, though depending on the hardware involved it is possible (yet nowadays unlikely) that this will cause swap to be written to the internal disk.

You can watch which device is being written to using iotop.

i see, will take a look on what iotop shows next time then, thank you very much!

Could you please give the result here after you checked? I got also curious if it's temporary copied to ram or disk before moving.
