Minidiscs should have won for both audio and data. They’re perfect for long-term archival storage and they’re just plain cool. If only Sony wasn’t so shortsighted.
I wanted a data drive for my mini disks so bad back in the 90s. It just never happened and writeable CDs happened instead.
A guy I knew in high school back then was actually working on that: turning a commercial mini-disk player into a data storage drive. He said it was really difficult because the (lossy) compression was baked into the hardware. I don't remember if he succeeded to any degree.
