I tried DLT7000's about 2 years ago, and had to dump them in favor of
Magstar-MP's. The DLT's had lots of problems reading the data they wrote
on the tapes, which is not good for backup/recovery. I have been using
DLT4000's for 4-5 years, and have had lots of problems with the drive's
internal tape leader becomeing "unthreaded".
As for performance, the Magstar-MP's are optimized for start-stop actions,
and that is much of what ADSM will do to a drive. DLT is optimized for
data streaming. In my experience, Magstar beat DLT hands down in both
modes.
I got tons of calibration errors on the DLT7000's. Quantum took my
BreeceHill Q7 to their labs to recreate the problem, but I never heard
back from them, as I got rid of them.
If we had the budget for them, I would buy 3590's in a 3494. The 3575's
with 3570-C1A drives are a nice, cheaper alternative. I just which the
tape capacities would double (10-30GB). For me, more than 30GB on a tape
can become a liability.
All of the above is MVHO...
