Wow, I'm surprised the VLC could generate enough traffic to wear out
an SSD - compared to a modern box running heavy compiles and suchlike.
Very cool box :)
Thinking about SCSI devices for my collection of older boxes - I
wonder if rascsi set to use the pi's RAM rather than an SD card to
provide a swap device would work out.
Actually, could be interesting to run a modern *nix box with the right
type of scsi adapter in target mode and have it "export" devices and
or ramdrives to older boxes...
