be careful with the benchmarks.  it's important to understand real workload
vs. streaming rate performance.  if you can stream continuously, the mammoth
will likely win.  if there is a lot of start/stop, the mechanics and motors
of the mammoth are not robust enough allow for good performance.  this is
what the 3570 has been engineered for and it will likely outperform both
mammoth and DLT.

>I know there is a benchmark which IBM has comparing Mammoth to DLT7000 to
3570 ... I'm currently trying to get my hands on it and will repost once I
find out it's location.  Based on the information I've heard, the 3570 was
the highest performing drive in this test, Mammoth was second ... likely
because of a high degree of start/stop activity ...
