I'm looking for a external HDD to store all my DVDs as MP4s for when I go to university (one box beats having about 20 boxsets + movies). It's going to need to be 300GB or more for this to fit. I've found this: Seagate ST3300801CB-RK. Seems a good price. Anyone of these who can tell me if they are an good? As I'm not going to be carrying this about (only going to be sitting on a desk) it's not a problem to get an internal one then incase it; but I've got no idea how this works or if it's safe. External power is also fine. I'm guessing that thouse that don't have power cords are small and more expensive.
