Repository storage question (RAID)

Semi-off-topic / semi-on-topic...

I'm getting ready to bulk out our storage for our repositories (and
there's other stuff running in the background, but that happens during
off-peak hours).

Would it be better to go with a 4-disk RAID10 made up of 750GB SATA
drives, or an 8-disk RAID10 made up of 320GB or 400GB SATA drives? Do
the extra spindles gain us enough to make the power increase worth it?

(This would all be Software RAID in Linux 2.6 done on a PCIe box with
plenty of I/O bandwidth.)
