I have a 3ware 8 channel SAS controller and a back plane extender (also 8 channel) which can take 16 drives. I will be creating a single RAID 10 volume.
I know that adding more drives has positive effect on performance, but I'm not sure if adding more than 8 drives on an 8 channel controller will have any positive impact at all. Am I wrong?
Should I put 16 drives for best performance? Would 8 drives give me the same performance?
