Shouldn't be called a "thumb" drive, unless you're Sissy Hankshaw.
Oh, and I thought these were interesting.
I was just reading about the Seagate BlackArmor NAS 440, which doesn't really make sense to me -- the drives are hot-swappable, and you can make multiple partitions, each with a different RAID level. I mean, I understand that under certain configurations, you're going to have to disconnect all of those partitions in order to swap out one of the drives, but what happens when you put another in, after the restriping process, to those partitions that you had at one of those lower RAID levels, if you had part of them on the swapped out drive? Do they shrink? It also does encryption, print-serving, ftp and https serving, and iTunes serving (?). Now if it only did mail-serving.
