The Zip Drive was really great in moving large files around.
I had a Parallel port ZIP drive and I remember it being quite slow.
It was alro really annoying if you daisy-chained your printer on to it.
The ZIP drive needed to be the first device in the chain, so it had the highest priority for data (as it was closer to the CPU).
This kind of hindered the portability of the drive, since then you had to unplug your printer, and you had to unplug the drive from the PC.
The Jaz drive was the real workhorse. I got exposure to that through my Dad's work, where it was possible to loan it for a day or so.
A few years later in 1998 I got an LS-120 "Super floppy" drive, that would read regular floppies, and the LS-120 disks that held the equivalent of 120 floppies. That drive was pretty good, but then USB sticks were just around the corner, followed by consumer grade CD Writer drives.
