I will be configuring six hard drives (2*250, 2*320, 2*500) and one optical drive for a system using the Gigabyte GA-P35-DS3R motherboard and I have a few questions.
Please note that the ICH9R controller has six SATA ports, while the Gigabyte IC controller has two SATA ports. Total number of ports is eight (8).
What is the effect of running the following configuration of RAID arrays in terms of performance:
RAID 0 (system) - ICH9R x 2 ports
RAID 1 (critical storage) - ICH9R x 2 ports
Non-Raid (optical drive) - ICH9R x 1 port
Non-Raid (non-critical storage) - GA IC x 2 ports
By having two RAID channels running off the ICH9R controller, would there be any decrease in read/write speeds?
Would having a Non-Raid item on the ICH9R controller affect the performance of the two RAID channels?
A friend also recommended the following configuration which he believes would be better as each array would have its own dedicated controller for its intended purpose:
RAID 0 (system) - GA IC x 2 ports
RAID 1 (critical storage) - ICH9R x 2 ports
Non-Raid (optical drive) - ICH9R x 1 port
Non-Raid (non-critical storage) - ICH9R x 2 ports
