Well, thats possible. The best thing to do is run benchmarks (I like iozone) on the proposed system and see what works best. The tests I did were just on small filesystems (1G volumes, 64M, 128M and 196M RAM). Filesizes I tested were only up to 500M or so. I found that while most tested filesystems (reiser, XFS, ext3 and vfat) did drop off in performance as filesize increased, XFS dropped off the most rapidly in that dimension. ext3 was the most stable (in performance as filesize increased), though its small filesize performance was the worst. XFS looked like kinda the opposite! :) Reiser had the worst write performance of all of them, but admirable read.
