The problem is, 3,5" drives use a lot of power (some 30W spinup); you cannot pull that much from USB cable so external enclosures for 3,5" drives will have a power adapter; this makes two cables while rsh wanted just one cable; you can only do that with 2,5" and below. So i recommend 2,5" drives. > I have a Sarotech Hardbox enclosure for 3.5" > drives and I prefer using Seagate drives inside. Seagate gets rather hot; Samsung is a lot better in that respect. - Veronica
