yes. it depends on how much total capacity you need, and whether
or not you fudge the accounting. (most disk bigots just use the cost
of teh drive and not ancillary stuff.)
and don't get me started on the issue of whether or not you want the
right
answer when you go back and get it later.
i do not have a large data site by modern standards (~200TB), but so
far, my asymptotic failure rate for tape (that is, tape going bad
after i write
and then a seperate read-verify pass) is significantly lower than the
error
rate of RAID hardware (going silently bad) or filesystem/OS errors.

didn't pop up anything obviously useful, but that's always colored by
the keywords used...
Are there any tape systems that have a lower cost per gigabyte than
1TB or 1.5TB sata disks?
