I used a Zip drive with an Akai MPC 2000 over SCSI to store all my songs and sounds. Loved it! Never had a problem with it, and I didn't exactly look after it well. The MPC itself still had the builtin floppy drive, and the zip just blew the floppy away in speed and capacity.

That me reminds me of installing a SCSI Zip drive into my roommate's Akai S5000 or S6000 sampler. He and I repeatedly debated whether or not hardware samplers would eventually lose out to software solutions. He was absolutely convinced that there was no way in hell that the precision of hardware solutions would ever lose out to the flexibility of software. In the end, I was right, I'm pretty sure the S5000 and S6000 were some of the last truly hardware samplers of the era. Still, that Akai was a sexy bit of kit back then. As sure as I was that software would eventually win out it was sad to see the amazing engineering and precision of the hardware that was finally overtaken.
