What if we forget the individual hard drives and think of archival
appliances like Drobo?
Benefits: connects to anything (USB, LAN, FW800), fairly low cost, fail-safe
with automatic defect discovery and data
recovery, fantastic data protection capabilities (equal or better than those
of RAID6, according to Drobo), i.e. protection from dual drive failure.

One of the really really neat features is the expansion capability:
replace the individual drive(s)
with larger one(s), (one at a time) it keeps
working, and once the volume is rebuilt, the larger capacity is
available immediately.

(I am not trying to sell it - in fact, we don't sell them. :))

Isn't this type of an appliance just perfect for long-term archiving?
 Redundant, large capacities, no manual intervention, i.e. no disc changing,
very easy to duplicate for off-site redundancy, fairly low cost, easy
expansion.  Neither optical media nor individual hard disks, nor even
popular redundant arrays have all of those features, and certainly not at
that cost.

Alex.
