USB 2.0 you mean?  It supposedly runs at 1394 speeds, but USB 1.0/1.1
runs at 1MB/s under ideal circumstances... that's slower than even old
IDE drives.

Probably not...

That's true... but on a per $$/MB, you're better off investing in RAM
and increasing your effective_cache_size.  If dd to a flash card is
faster than to an IDE drive, please let me know.  :) -sc
