"All other drives except USB are way more expensive,and hard to find.I also have WD My Studio Passport Firewire Hard drive."
You're probably not going to find something in Best Buy. There's plenty of external HD's that have other connection options, but you'll have to get them from places like amazon and newegg. An even better option would be to just buy regular internal hard drives, and put them in external enclosures. (Just to note, all external hard drives are either 2.5 or 3.5 inch internal HD's in an enclosure anyway.) HD enclosures are not expensive. If you live near a Tiger Direct store, you may want to go there as soon as possible. About a week ago they announced that they will be closing all of their stores, and are in the process of liquidating them as we speak. Just be careful and check the prices on anything you buy with other stores first. Some items they lowered the price on, but on other items, they actually raised prices quite a bit. Believe it or not, people seem to be buying the expensive stuff like it was actually on sale.
