Howdy,

  Having seen all the past messages about the poor (to be kind) reliability
of "DDS" (and we've replaced a few in our day also), I wonder what the
current feeling on the latest DDS-3 drives are vs. the DLT-7000s?
  From HP's specs, the DDS-3 sports a 300,000 mtbf, while the DLT-7000 only
sports 200,000 hours...? If *HP's* listing them as *less reliable*, should
that tell us something?

  With DLT-7000s listing for (what was it?) $13k* each(?), with 2-3 times
the capacity of DDS-3, and twice(? my memory fails and I don't have it in
front of me at the moment) the throughput... I'm wondering if the jump to
DLTs are really worth it?

  Any opinions? Are *all* DDS drives just evil?

*=HP List price

P.S. For any HP folks reading; the DDS2 spec sheets on the hp.com web site
    have a nasty typo in throughput; I believe the "compressed" numbers are
    in Mb, not Kb as listed. :-)
