Cool!
I found the old drive that worked with my Canon camera. It's a Hitachi 2GB Microdrive from 2003. It says CF+ Type-II. So larger, with a CompactFlash interface, boring in comparison.
More history: https://en.wikipedia.org/wiki/Microdrive
I'm trying to remember the camera... Canon Powershot S1 IS maybe? It used a lot more battery running the microdrive.
Is there a video somewhere of the one inch microdrive with acrylic display shown in the article?
I remember my Nokia N91 which had a 4GB version of one of these tiny HDDs, blew my mind at the time.
Man do I miss the N-series, I had so many good phones in that era.
