I would agree with Bruce.

Some additional info: The block size on ext2 / ext3 may be altered
when you format the disk using the ``mkfs -b block_size'' flag.
Common block sizes are 1024 and 4096 bytes.  Setting a small block
size makes storing lots of small files more efficient, because a file
will take up at least one block no matter how small it is.
Unfortunately larger block sizes have noticable performance gains.

Note also that there is an interaction between block size and stripe
size if you're using ext3 over RAID.  The Software RAID HOWTO
explains.

Reiserfs has failed on me in bad, unrecoverable ways a couple of
times.  Not good.

Yup.
