could you be a little more clear on what kind of setup you're looking for? you mention partitioning, which would mean to take the one drive in your desktop and divide what's being used and what isn't. in that case, all the files would be accessible at any time.

if you want an actual separate drive, i would recommend (if you have a free 5.25" bay free on the front of your computer tower) a hot swap. a decent one will have a power button for the drive, as well as a locking mechanism so the drive doesn't just pop out.

see attachment for reference. they're called hot swaps, hdd swap trays, etc.
