Doh, goofed again!  Let's try this again ...

  DVD ~ 2.0GiBph ~   120 hours -> 250GiB
 ATSC ~ 8.5GiBph ~    40 hours -> 350GiB
 MP3* ~ 0.1GiBph ~ 1,000 hours -> 100GiB
                                ---------
                                  700GiB

800GB ~ 745GiB, which means I've got about 45GiB for the OS, swap,
etc...

I'll use MPEG-4 to store long-term ATSC broadcasts into about 1/4th the
size.

Eventually I'll probably upgrade to 500GB disks at some point (maybe
2007?), which will be the 2TiB maximum of the PC.  The NetCell SR5000
presents itself as a traditional ATA disc, so I don't know if there is a
2TiB limit or not (probably not in Linux?).

BTW, I plan on using Fedora Core 4 (which should be out at the time) and
XFS for the media volumes.  XFS is ideal for large files -- much faster
than Ext3 and much, much, much faster than ReiserFS at large files.
