Can somebody explain to me why it's worth considering putting a Squid cache
onto a Raid setup anyway?

My thinking is:

Raid is for precious data where you don't want to lose anything because of
hardware failure (which is reasonably likely with hard disks, depending on
how long you wait).

A Squid cache is not 'precious data' but you want the access to it to be as
fast as possible, and you want to get the maximum performance for your money,
therefore you don't want to pay for an extra drive toget the redundancy of
Raid.

Therefore, I cannot see any purpose at all in putting a Squid cache onto Raid
- surely if you have multiple disks, it is better simply to create a File
System on each, and put those into your squid.conf file as multiple
"cache_dir"s?

Perhaps someone can enlighten me on this.
