We're using 10 - DLT7000 drives in a STK9710 library connected to an NT ADSM
V3 server.  The tape mount time is about a minute.  We see no problem with
the mount time or the tape seek time of the DLT drives in a backup/recovery
situation.  If we were doing real time data logging or something like that,
then it would be a different story.  We've had no serious DLT reliability
issues.
