Yah, RAID-6 at a minimum, I wouldn't depend on RAID-5, even with a 
hot-spare.  So to get 10TB, you'd need 13 drives (10 data, 2 parity, 1 
hot-spare).

And make sure you buy enterprise level SATA disks (the 1TB models are 
about $150 right now).

(You can fit 15 3.5" drives into a SuperMicro 4U 942i 760W case with the 
5:3 SATA mobile racks.  The 942i is also a very quiet case due to using 
120mm fans inside.)
