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.
