Our two cache servers are running with Solaris 2.5 and 2.5.1 and using
DiskSuite to stripe 4x2Gb discs into a single partition for the /squid/cache
directory. We're using striping, rather than multiple directories,
because experience has shown it to noticeably increase performance in
other similar applications. So far it seems to work very well.

I would recommend going from 2.5 to 2.5.1 though, since we've had a number
of problems with the 2.5 machine. [Most notably the mutation of ".."
directories to ",."!].
