I agree at once with RAID 5.
Striping should speed up disk performance the same way squid uses multiple disks, don't you think?
Therefore it shouldn't make much of a difference, if I break up our striped cache volume and use those disks independent from each other especially when both are connected to the same controller.

you should never use RAID for squid cache directories because it always
degrades filesystem performance for squid.


RAID 5 will kill Squid performance, but other types shouldn't have much of
an impact beyond the normal effects of that RAID setup on I/O performance.
