Tapetype reported speed at 2811kb/s and the vendor supplied data is 3mb/s)(3072 kb/s).
that's about 5% only.. so I guess you were right?
1 questions - tapetype reported length at 38794 mbytes, and the vendor
says 40mb, couldn't this shortage in length (so to speak) also be
because it uses 32kb filemarks instead of the recommended 128kbit?
Well anyways, you are right that this is not that big a performance
issue.. I'll start testing with the current setup, as soon as I find out
what filemark means :-)
