If I recall your typical laptop only has one connection. 17" gaming laptops though often have two drives. The techs either attached it to a laptop hard drive rig and to a regular sized pc, or a full size rig if its a full size drive.
Good that its covered, guess you got yourself a laptop now (or another one anyhow)
Cute toy, though usb is slow as heck for any major file transferring (took me close to 24 hours to transfer 500gb). Also the advert makes it sound like you can use it on any drive (i was wondering about power though)
