So I've heard.  I'm not a big fan of ReiserFS.

All my other filesystems are ext3.  Though I had heard that
some other journal-based FS's do better on RAID 5 because 
they constantly write to new sections of the disk as part of the
journaling transaction rather than writing to current blocks.
I guess it has to do with the ordering of the free-list.

I could be grossly misinformed though.

Nice!

That's been a major factor in my current choice.  However, I
am open to new suggestions.  Especially from people who
know more about this than I do.  :-D
