Hi Randy--
It is amazing to calculate (maybe too amazing?) that a 1TB drive,
sans enclosure does cost the same as 250 good, DVD-R 4.3GB discs.
Tech support at Other World Computing and my friends who run servers
at the University have been telling me that 1TB drives are now quite
reliable but that 2TB's aren't there yet. Got a link to the dual
enclosure you have in mind for that budget!? Rob D.
