At 9.1GB, you may be looking at a DVD-RAM drive. I do not recall seeing any >5GB MO stuff. (In fact, >1.3GB MO stuff seems to be exceedingly rare.)
It would be interesting to hear what people do for backups on their old computers. I never bothered to backup my old Macs when I was using them, but I've been wanting to get back into the "actually using old machines for stuff" scene once I'm done with my classes, and have been thinking about the hardware investments I may need to make, in terms of data storage and data backup.
I know a lot of old UNIX machines had DAT/DDS drives, and some Macs had them, and MO seems popular for its almost legendary reliability.
As backups for modern machines go:
Another technology along the same kind of thought (optical disk in a cartridge) is Sony's Professional Disc. Unfortunately, these are very very expensive, and for 10x the cost, have the same capacities as BD-R and BD-RE. (Which, I priced it out six months or so ago, is the cheapest way to make a single backup of 6TB of data, not counting the costs of running machines or sitting in front of the machine swapping 100 disks in and out.
In a lot of cases, the easiest and cheapest way to "backup" (at least to have one working backup copy of info) is to back up onto another hard disk. (I've been having good luck with a 4TB Seagate external drive, it was "only" $250, and it holds most of the data I need to back up. I'd like to supplement it with one or two more when Windows 8 and storage pooling comes a little bit further along, or get Open Indiana or Solaris 11 or FreeBSD and some ZFS pools going.)
