Howdy, As Peter said, the connectors for 2.5" and 3.5" SATA drives are the same. But, the power draw is almost always a lot more on the 3.5" drives. A single USB port can supply 2.5 watts(.5 amps at 5V). For example, a Seagate 3.5" ST3500320AS 500 GB takes .65 amps at 5V and .42 ams at 12V. USB does not supply 12V at all. 2.5" drives are almost always 5V only and take around 2.5 watts(I've seen up to 5 watts). So, a 2.5" drive may work and a 3.5" almost never will. Some higher power 2.5" drives need power from 2 USB ports. I have burned out a USB port from drawing too much power. Good luck, Ralph
