for example. XFS also has the advantages that it supports write barriers (but not sure if the one in 2.6.18 already does), so you could probably enable the host adapter cache, and that it handles well very parallel access patterns. It has the disadvantage that it can require several GB of memory to 'fsck' (like 1GB per 1TB of filesystem, or more), and does not work as well with lots of small files (while ReiserFS is very good, and JFS not too bad).
This no longer need be the case, (xfs_repair memory usage). Improvements were made in xfs_repair 2.9.2 and later - quoting one of the develpoers: "Right now, I can repair a 9TB filesystem with ~150 million inodes in 2GB of RAM without going to swap using xfs_repair 2.9.4 and with no custom/tuning/config options."
