It's A Digital Disease!

Hi all. I've obtained a used 3.5 12TB HDD, now looking to do a full read/write surface test before putting into service. My previously largest 4TB external USB HDD took around 13hrs. I'd prefer to run the test at a time it's least at risks of disruption from knocks/shaky washing machine next room, but if it takes nearly 40hrs that's a real challenge...so shortening the time is of interest. I intend to run it in a 3.5 enclosure that has 1xUSB3 and 1xUSB2 plug to run into the PC.

I'd appreciate if any of you highly experienced folk had guidance on what is most likely the limiting factor for surface scan speed? From CPU of the PC, to the enclosure, to the drive itself? I'm also open to any other guidance in general.

Thank you!
