Perhaps RAID 6, as I've never heard of RAID 5 with two parity (two parity is dual parity which is RAID 6).
Forgot to mention my own personal preference on my high end SAN at least is for RAID 5 with a 3:1 parity ratio, or a max of 5:1 or 6:1, really never higher than that unless activity is very low.
The RAID controllers on my array are the fastest in the industry, and despite that, in the near future I am migrating to a parity ratio of 2:1 to get (even)better performance, that brings me to within about 3-4% of RAID 1+0 performance for typical workloads.
