It’s RAID. With Floppy Drives. (hackaday.com)

The article does not include the most critical detail: the speed!

Edit: I have watched the video so you don't have to (although if you don't watch it you'll miss all the bubbles).

Total volume size: 10.4MB

Small file: 220kB/s "Large" file: also 220k/s Installing chess: 1MB/s

That said, he's getting the speed from Activity Monitor which seems like an odd choice. I would have preferred the more obvious one of writing a fixed amount of data and dividing that by the time taken.


For comparison theoretical max HD floppy speed is ~45KB/s

>Small file: 220kB/s "Large" file: also 220k/s

This speed seems plausible. Every USB floppy has little microcontroller based controller with some small cache meaning you can keep filling buffers faster than individual drive speed.

>Installing chess: 1MB/s

which is more than theoretical maximum of 13x45KB/s, immediately invalidates whole highly scientific 'Activity Monitor' measurement method used :)
