Indeed. I was making sure he wasn't raiding his squid cache. :-)

wow, that's very much of data transferred in a week.

1-2 weeks are recommended, if you can set up a few FAST disks.

you should use each drive as separate cache_dir, unless you use mirroring
(which is useless in many cases)

the 'noatime' option for most filesystems does not matter.

if your computes has enough of memory left for metadata cache (inodes and
directories where squid data are left), it's OK. if not, you have huge
performance bottleneck here (and with only 50 MB of cache_mem, buy more
memory).
