Mhh, the real enterprise stuff is moving to raid 5.  If you have a hardware 
raid storage with battery backupd write cache, raid 5 has the same speed as 
raid 10.  The software algorithme in the hardware raid box is very smart.  
Some time ago you got a a free performance boost of 50% just by updating the 
firmware and thus the caching algorithme.
This is fiber attached storage stuff, I'm hoping to get a used 16x70GBx15krpm 
fiber box with 16 GB cache, mhhh .......
