Well in this case the RAID controller does play a significant role.
Since the drives are logical and purely handled by the controller it
also decides about teh read/write and queue operations trying to keep
all 4 drives equally busy and the spindles in sync.
Note: The transaction patterns reaching the controller is mostly the
same, regardless if you have one or many partitions. Because of this
there is no benefit in performance for Squid to have more than one cache
partition per set of drives in a RAID.

*nod* looking at it in cachemgr.cgi it is doing pretty well, but right now there is not enough traffic in the house to test it properly.

You are of course correct and I shall implement your suggestions tomorrow.
