Well, you saw my results.  I'm happy with the speed and this is a server 
for fondling uncompressed video.  So while I want to maximize the speed, 
I'm not going to take "unnecessarily foolish" risks with a filesystem 
that (at least to me) doesn't seem like it's quite reliable enough. 

Seems like the answer to your problem is just to buy 4 more disks.  :)
