The number of drives the RAID set is built over is set by the parity
optimization selected when you start RAID.
You can select an optimization type of: Availability, Capacity, Balanced or
Performance,
The striping is more influenced by the controller than the disk units
themselves

Are these SAS drives or SCSI drives? I may be wrong but SCSI drives did
their raid striping over 2, 4 or 8 drives, depending on how many drives
were in the raid set when you first fired it up.
