Here's the quick and dirty. I need to buy an external HDD. Which form factor, 1.8" or 2.5", and which brand. I prefer Lacie but willing to buy something else and must have USB2 though I prefer usb2/fw drives Here's the deal, I lost my 1GB flash drive. I was in a rush and forgot/assumed i had it plugged into a computer in my university's engineering computer lab. It was a PQI Intelligent stick drive (black and a size of a stamp, plugged into a black computer, go figure). I'm bummed out that I lost $80 and in search of a replacement. I figured instead of paying another $80 for a gig flash drive, I could just get, for a little bit more, a small external HDD. I already have another flash drive (I'm one of those people that buys technology products when they are on huge sales even though I don't need it) so I don't need ultra portable storage. I'm specifically looking at 1.8" and 2.5" form-factor external HDDs. I see that the 1.8" drives cost 2+ times the cost/gb as the 2.5" drives. Is the price worth the size? How durable are the 1.8" drives compared to a 2.5" The specific models I am considering is the Iogear 1.8" 20gb drive, or a Lacie 40gb 2.5" drive. But honestly, I am looking for the best drive for the money in terms of speed, size, capacity, and durability (I've always bought Lacie, and they never fail. 90% of my Family's external drive purchases are Lacie) I'm leaning toward USB2 only because they are cheaper, and I work with a mixed environment of my 12"PB and the Mac's at home, and all the Pc's my friends have and the labs. I don't really see a point of paying extra if I'm only going to use USB, unless there is a huge speed difference (I've read that combo drives usually have worse performance, or maybe that was drives with both fw400 and fw800 and the lacking speed on the fw400 end). Sorry for the long post.
