SQL Server with Mr. Denny

If you have 12 disks to hold DB Data files and decide to use RAID10, would you create 1 RAID 10 group or 2 RAID 10 groups made of 6 disks each for best read/write performance?

I would probably make 2 RAID 10 RAID groups one for the data files, and one for the transaction log.  Without knowing what percentage of data access will be read and what will be write I’m just guessing here.  Depending on the load RAID 5 may work just fine for the data files.
