No.

No.

You should avoid having two cache_dirs on the same physical disk. Squid
is most happy with one cache_dir on each disk or stripes of several
disks.

Using RAID5 is currently a bad idea and will give poor performance (many
random writes == worst case for RAID5). Either use no disk redundancy or
use mirroring.
