Don't you get creeping data corruption on 10+ worth of TByte drives? 
And not even RAID6? I'd definitely get drives from different batches,
or preage them randomly.

I'm speccing such a box right now with a Supermicro 2U box, and I'm going either
for FreeNAS 0.7 (bleeding edge) or OpenSolaris/NexentaStor, both with zfs.
