I think more about longevity and sheer size.  I think in Sean's
original paper or the wiki it mentions making arenas some reasonable
size -- say 650MB -- so you can make archival copies of the arenas in
case of disaster.  Burn an archival-quality copy to CD (or multiple
CDs) and store them away for seven years in redundant locations, and
you're well on your way to meeting a whole slew of legal requirements.
 If you get paranoid about the live arenas, you can always go back and
compare checksums against the archived versions.

Plus, if you're saving seven years' worth of data, venti seems a
little more efficient at using the available storage space (*WARNING*
-- layman speaking).  Now, using WORM drives for venti arenas might be
even better....

I did chuckle at the statement about shredability, because I often
picture RIAA or the BSA rooting through someone's venti archive
looking for copyrighted material.  That MP3 deleted two days later
just lingers, waiting for the right lawyer to come along.
