Using squid he could define one cache-directory for every disk, so striping won't increase performance of the disks that much. more important might be how the os is caching write changes to mitigate limited bandwidth (io) of the disks. With ReiserFS I have seen some benchmarks that are not really in favour, like http://linuxgazette.net/122/TWDT.html#piszcz and my experience with UFS2 (albeit on FreeBSD) was much better than with Linux/ReiserFS on the same machine. Neither were tuned, though, so ymmv. Regards, Holger Kipp
