Ghassan,
I'm not sure adding additional hard drives will improve the performance of
Squid a great deal, if you're caching a lot of large objects over a long
period of time then it may prove beneficial. But if you're looking for
performance you would be better investing in more memory, if you can serve
the majority of 'hot objects' (frequently accessed pages / content) from
memory your response times will improve greatly. The response time for
retrieving an object from disk will be much greater due to the overhead in
disk / controller I/O.
maybe it will be slower then ram but a 15k sas drives will speed up the
HDD doubles two the SATA ones.
in any way on a busy network with a log of objects it worth every peny!!
on a cache of a friend he used SATA drives for a very busy network and
there was a lot of difference between the 15k SAS to the 7.2K SATA drives.

Hope that helps
