	Actually, here at the Applied Physics Lab, I'm having to set-up
a MassComp 6700 to save data at 4Megs/sec (!) to *keep up with a VCR*!
Apparently, the VCR (digital of course) can send data at 2M/sec or 4M/sec,
and the US Navy (SeaData aqcuisition) would of course lik the fastest possible.
(In case you're interested, I'm interleaving three 1Gig SCSI drives at 1.5M/sec
each.)  So, by my calculations, that makes an 80Meg backup possible in 
*20 seconds*!  Who says back-ups are a pain?

	Of course, you'd have to write a device driver, and build an interface
board, and... :)
