tiny. Of course, it's not as small as the really tiny drives in iPods; 2.5“ drives are standard in laptops. I just ordered this new 80GB drive to replace the 30GB in my iBook. All these photos for this site take up a lot of space! The new drive is also a little faster, spinning at 5400 RPM, rather than the 4200 of my current drive. One of these days I'll actually try to install it, but I'm making myself wait until the semester is over so that if I destroy my computer in the process I won't be in such a bind.
