Finally, a use for that drawer full of 1 GB USB drives!
When Sun Microsystems was still existing they made a (quite funny) video putting 12 usb sticks in a ZFS pool with RAID: https://constantin.glez.de/2011/01/24/how-save-world-zfs-and...
It lasted a couple evenings while I bumped into apparently every Linux USB driver/chipset issue possible trying to drive a couple hundred drives via cheapo AliExpress USB hubs.
It was fun times, but even more useless than I originally thought it would be. It was amusing to get >1GBps for a minute or two across 256 crappy thumb drives though!
