I am just starting to look into this RAID and I was wondering wouldn't RAID01 
be better then RAID10?  In a 4 disc system having the first two using 
stripping and then backing them up the second set with mirrors?

My though is having D1 and D2 as the primary drives stripping and then having 
D3 backup D1 and D4 backup D2.

And if enough room place a couple more drives in the system as hot standby's.

Or am I looking at this all wrong?
