When TCQ becomes a reality in IDE drives, they'll have a fighting
chance, but the slower seek times and rotational speeds will still
do them in.

Also, does an 8MB cache *really* make that much of a difference?
After all, it can only cache 0.0067% of a 120GB drive, and 0.00267%
of the new 300GB disks.

Speaking of which, that 300GB HDD sounds like a dream for near-
line storage, and even for nightly backups, if it is ever put in
SBB-type packaging.

Imagine a scheme where you rapidly pg_dump to the 300GB drive, 
then, at leisure, tar the dump file to tape.  Stripe a few together,
and keep a month of backups on-line for quick recovery, along with
the tape archives, in case the stripeset gets wasted, too.
