I'm starting to doubt what I've read. I guess it depends then. Crawling
the net, I seen/heard references to use reiserfs with notail/noatime
options instead of ext3.

but Duane Wessels's book "Squid:The Definitive Guide" has benchmarks
that show better performance on ext3. (Refer to my reply to Martin Marji
Cermak)

Frankly I'm not sure. Most ppl on the list does not encourage using
RAID. I only run the cache on 1 SATA disk.

This is as per-written on the Squid's FAQ. (IIRC)
