wtf does raid have to do with anything here? yeah, sure, I’m the slow one.

or you could, you know, think about it for a second from their point of view. and they have already clarified this in other comments.

what is the point of faster download if you just have to do another entire copy after that?

what OP wants is to download the file to a SSD, be able to use it on the SSD for a time, and then have the file moved to spinning disk later when they don’t need to wait for it.

this is just adding an extra step to the process before the file can be available to use. you’re just saving the copying to the HDD until the very end of the torrent.
