  Oh, you're right.  I had just checked quickly, and the page said
"800 GB" with a footnote.  I just assumed they were doing the typical
marketing thing (i.e., lying), and cut the number in half.  Turns out
they were being honest; the footnote is about "1 GB = 10^9".  Color me
surprised.  Sorry for the bad information.

  So that means $0.138/GB.  So tape is still cheaper than disk.  (For
the media.  Factor in the tape drive... not so much.)

  Right, but that's $0.25/GB.  Smaller disks are cheaper, unless your
data set is only just over 750 GB and not expected to grow.
