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... David
