Let me say that as a student who had to do the backups, this drive was a godsend compared to our suns that used 60 meg cartridges. Megatape now has an 8mm tape drive (alas we don't have this one). As for the ExaTape, we have four of them for our Sun fileservers and the speed is incredible! They took a 12 hour backup and reduced it to 1.5 hours, and from MegaTapes flyers on their 8mm the backup rate is about 2.3Gig in 4 hours. I have 0 experience with optical disks, but aren't they write once/read many? that can get expensive. I would recommend the 8mm drives (tapes are cheap $9 around MN and the speed is great) > thanks, > dj your welcome Darryl Bergstrom Honeywell Corporate Systems Development Division, Golden Valley, MN UUCP: {uunet || rutgers!umn-cs}!hi-csc!bergstr ARPA: bergstr@hi-csc.honeywell.com -=OR=- darryl@ux.acss.umn.edu -- -Darryl Bergstrom -Honeywell Corporate Systems Development Division, Golden Valley, Mn -UUCP: {uunet || rutgers!umn-cs}!hi-csc!bergstr -ARPA: bergstr@hi-csc.honeywell.com -=OR=- darryl@ux.acss.umn.edu
