Are there any differences between external HDs other than price? They're all basically 7200rpm, and the ones I'm looking at are 80GB to 120GB (only need basic storage, don't care about capacity, really). Some have 8MB buffers, and some don't say anything about that. Not quite sure what that is, so maybe its not such a big deal. I'm sure I wouldn't notice the difference. I went looking for one today, and I saw what they told me was an "older model" Maxtor 80GB (or maybe it was 120GB model) one that takes FireWire. It wasn't one of their "OneTouch" models, but it was cheap, and around the same size as the others (I was told). After I read that it had FW, I'm pretty convinced that I want an external HD with FireWire and not just USB 2. But Maxtor has some for beginners and experts and professional designations in their line-up and its all getting to be a bit too much for me. I'm sure its more of a marketing thing than anything else, right? I also saw some IoMEGA externals, but I wasn't sure if that company was good. What happened to Seagate? Western Digital? Are there others? I realize that LaCie are well liked around here (I do hang around MR sometimes ), but I don't know why they're better than the rest. Also, LaCie HDs start at around 160GB at the nearby store and are approximately US$60 more than a poor student wants to spend.
