Ah, Dom Franco (with my best Italian accent--being half Italian and all),
The Orb Drive is a removable media drive. They use a cartridge with a 2.2gb capacity (@2.16gb after formatting). This is about 1-1/2 hours for 4 track, 45 minutes for 8 track. Cartridges run between $25-40. Now that's about 22 100mb Zip discs, 8 or 9 250mb Zip discs. Not bad. And it is as fast as many harddrives. The drives are made in SCSI, IDE and USB interfaces, internal and external and run $179-230, which includes one disc. I have the external SCSI and have been very pleased. Works flawlessly so far. For FD users, it does format in all three modes.
Peace, Jim
