Not to be confused with Apple's SuperDrives, SuperDisks were a 120MB competitor to Iomega's Zip disks. As a bonus, their drives could also read regular 3.5 inch floppy disks, and I've confirmed they even work under Snow Leopard without extra drivers!
When I was in high school in 2004 I was tasked with moving my English teacher's data from her green iMac G3 to her shiny new iMac G4. I think she expected me to use disks, but I took a cross over ethernet cable, configured some static IPs and had it all done in 15 minutes! To thank me for helping her, she gave me her green iMac and her Imation SuperDisk drive which she no longer used. Nice lady!
I never owned a single SuperDisk given Zip disks were well entrenched in the family (I had around 70 of the things) but to this day I've used the drive with my Macs to read regular floppy disks. It requires a power supply unlike other USB powered floppy drives, but I've read anecdotal evidence that it reads disks twice as fast as a regular drive, and is almost completely silent. For those of you who remember regular floppy drives (CHUG CHUG CLICK CLICK CHUG CHUG READ ERROR) these are two huge pluses!
Anyway, after a trip from Singapore back to Sydney recently in a poorly packed box (thank you Allied Pickfords) I tried it on my new Mac Pro and she still works!
Now its time to backup all our floppy disks. We have bags of them, many containing family financial documents from the 1980s. We still have a copy of 1-2-3 to read them… right?
