Interesting that in that time all kind of external storage solutions emerged: I used Zip drives, the follow-up "Jaz drive" (1GB) and Syquest disks (270 MB?). The latter two chained together with thick SCSI cables to a PowerMac 7200.

Edit: Today I use just 2.5" SSDs in the same way. There's a small sata to usb-c adapter where I plug them in without any further enclosure.
