With flash drives being so cheap and available, unless you need to transfer
very large amounts of data there is little reason for external USB hard
drives.  I carry my little 8Gb flash drive in my pocket everywhere I go.
It's my backup and I also use it to keep the three machines I'm routinely on
in sync, which then become further backups.

Flash drives are slow and small in comparison to hard drives, but are
certainly small and low power.

By the way, I found out the hard way they don't go thru the laundry well.
At least that gave me a excuse to upgrade from 4Gb to 8Gb.
