RAID 6 for this, as we've been doing on other RAIDs.

That's significantly bigger than what I have running, but I have heard of people running XFS on larger filesystems than I have.

If you're making one large filesystem out of that, the warning James mentioned is even more important: you will want a boatload of memory to xfs_repair that fs quickly. The rough rule of thumb I've read (which is probably akin to the 2x RAM==swap guideline) is at least 1GB of memory for every 1TB of storage, but the more the better, I'd wager.
