Yes, you might do that...

It was me in a previous message..
Unless I'm mistaken, I thought squid is storing data alternating cache-1,
cache-2,... cache-n (when n cache_dir entries). When the caching disks
are dissimilar then the smallest disk would reach it maximum before the
cache_swap is reached... [I don't know exactly what kind of error it would
generate or even if it's fatal..]
