The thing I would ask is would you not be better with SAS drives?

Since the comments on Dell, and the highlighted issues I have been
looking at HP and the the Smart Array P600 controller with 512 BBWC.
Although I am looking to stick with the 8 internal disks, rather than
use external ones.

The HP Smart Array 50 is the external array for SAS drives. Not
really looked into it much though.

Ben
