Actually, I don't think the FAQ does say that. (Searches on speed, rpm, 5400, access, drive, disc, and disk revealed nothing useful, anyway.) The drive upgrade guide says it in almost exactly those words, though.

Edit: BTW, I like the way the search deal works now, where it only shows you one entry, plus all the other questions, when you click on one. Could we get it to work that way when browsing it, too, Drakino? (Maybe it's not new, though, and I'm just a moron.)
