I saw Hitachi 1TB drives for $69 (AR, $79 before) yesterday. That is a
new low AFAIK.

I wonder about that - to create, say, a 2TB filesystem would require
likely two to three times as many 2.5" drives to create an array
similarly sized to one built with 3.5" drives (biggest 2.5" I've seen
is 500 Gig, but at 5400 RPM, best compromise drive would be a 320 Gig
at 7200 RPM), those additional 2.5" spindles might eliminate the
power-savings of the smaller form-factor drives...
