No point really. Squid already does the load balancing on multiple cache
directorys/disks. RAID0ing the cache directory would just be a waste of
CPU (or fancy hardware) and when/if a disk did die in the stripe set it
would take out the whole cache. With Squid, if a single disk dies, then
you just lose the contents of that disk - the rest of the cache dirs are
ok.
