The current 7k drives all have 8Mb buffers, which let's them hold enough data if they have to re-wind and get back upto speed. That takes about 1.5 seconds to do.
My reference is the "DLT University Handbook".
Luke> Any idea how to determine how large the buffers are?
I'm not sure, you'll probably have to go and beat on your vendor. There might be a SCSI PROM page on the drive which gives those specifics, but more likely just giving them the serial number of the drive should let them tell you what it's got.
