I am looking to buy a portable 2.5" external hard drive for my Macbook Pro since I will be traveling in the Fall and want something easier to take with me than my 3.5" externals. I've been looking around a bit and so far the best bang for the book looks to be the WD My Passport. I would love to be proven wrong though; I have looked for firewire drives but they are all in the $200 range and I'd rather not spend more than $150, and USB performance is acceptable I guess. I'm still sort of deciding between 250GB and 320GB drives, but I figure more space is always better. It doesn't seem to be any cheaper to buy my own external enclosure and internal hard drive to piece together myself on Newegg, but like I said, I'd love to be proven wrong. Things I will use this drive for: mainly backup for the 160GB drive on my MBP. I have about 30GB worth of projects right now and will probably be adding another 15 Gigs to that this semester, plus I would like some space for music media (movies not so important). I do graphic design work on my MBP, so that's what's getting backed up, as well as office documents and whatnot. I run Tiger so backup right now would have to be manual or by SuperDuper, but I am considering Leopard, since Time Machine seems to be such an easy backup utility. But I might wait until Snow Leopard. Anyone want to talk about their portable hard drives? I'd welcome suggestions.
