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. http://www.msicomputer.com/support/formviewer.asp?esoformid=94 Looks like the Via VT8237 Chipset manages the Raid setup. http://www.msicomputer.com/product/p_spec.asp?model=K8T_Master2_FAR&class=mb Here are some benchtest numbers, but remember these are with large data transfers. I do not think our chess programs will utilize this capacity. http://www.viaarena.com/?PageID=311 http://www.viaarena.com/?PageID=312 kburcham
