Yes - ReiserFS is much better than ext3 at handling large numbers of small
files, which is a similar usage pattern to a Squid cache_dir.

Not any more than using multiple cache_dirs, one per disk. One added
drawback to RAID-0 is that a loss of one disk in the stripe loses the data
in the entire stripe, whereas with multiple cache_dirs you only lose that
one cache_dir's data.
