That doubles your chances of losing your OS! My current server has five spindles - 2 in a RAID1 config for the OS and 3 as JBODs for the cache. If a cache disk dies then I remove the cache_dir entry for it until the disk is replaced and then reinstate it (after a squid -z). I'm not going to worry about the contents of those disks.
