The exact opposite.

Squid cache workload is THE worst case scenario for a RAID5 system. It
is hard to find any worse real life workload for RAID5 than Squid cache.

If you want to raid your cache then use mirroring, not RAID5. If you are
today considering 3 drives RAID5 then I would recommend considering 2+2
drives (4 drives) in mirror setup in two separate mirrors (no
concat/striping).
