disk. it boils down to how much data do you want to put under one 
read/write stream.

the other thing is that these days 1.5TB disks are the best 
bang-for-the-buck in terms of storage/cost. So maybe thats something to 
consider, and limit disk usage down initially - expand later as you need.

Even better if your hba can support that, if not then mdadm ( have lots 
of cpu right ? ), and make sure you understand recarving / reshaping 
before you do the final design. Refactoring filers with large quantities 
of data is no fun if you cant reshape and grow.
