The only difference I could find is that the bluetooth one is officially switch compatible and the other one isn’t. I have the old wireless one with hall effect sticks and had no issues with it on pc, android or steamdeck.

Largest one I ever did was around 4.something TB. New off-site backup server at a friends place. Took me 4 months due to data limits and an upload speed that maxed out at 3MB/s.

Make sure it’s in AHCI mode and not RAID. It’s probably a setting under storage, at least on newer ones it is.
