This is something I was just thinking about last night for a new server 
I am planning..

I would imagine to get RAID10 would require (assuming a 4 drive setup) 
you to create 2 RAID1 mirror sets and then using those create a RAID0 
stripe.. I haven't attempted this yet and don't even know if its 
possible with software RAID yet.. Would be cool, performance and 
redundancy.. :)
