I assume you refer to "Raid O Striping".
This in theory splits data and writes to both drives at same time. I tested this
raid o with two 20 gig Barracudas, did not see a performance increase with chess
programs. maybe 4 with raid setup will be measurable, not sure.
I know many sites have tested with hard drive benchtest software and gotten
better numbers with raid---but actual noticeable differences with chess program
is different. example--kns or total knodes in a given time for a test position,
or maybe time to solve.
I think the people that transfer a large amount of data at one time will see a
difference in load or download time---example load moves onto hard drive all at
once. this type of huge data transfer we will not see with chess programs.

I do not believe MSI would use a controller to slow the hard drive.

Looks like the Via VT8237 Chipset manages the Raid setup.

Here are some benchtest numbers, but remember these are with large data
transfers. I do not think our chess programs will utilize this capacity.
