I have a P8Z68-V Pro Motherboard and two 500GB 7200rpm hard drives that I used to have in a RAID0 configuration using the Z68 bios level raid. However, I've run into trouble in the past trying to multiboot, as some OSes see through the bios level raid. Because of all the trouble I'm thinking of investing in a RAID controller rather than continuing to struggle with fakeraid and such. That said, I have 3 questions concerning a controller.
Althought not my primary motive for getting one, would a RAID controller add any performance over the bios level RAID0?
If I connect the controller to the motherboard and the two 500GB drives to the controller, will all operating systems see only a 1TB drive (ie. Windows sees a 1TB drive and the array appears in linux as simple /dev/sdx and not /dev/mdx or /dev/mapper/)?
Finally, I know nothing about different types of controllers, but from a glance, if I were to get a simple controller like this (http://www.newegg.com/Product/Product.aspx?Item=N82E16816104015) would it work fine or is it worth investing in a more expensive controller? I'd also appreciate if anyone had any suggestions as far as brands or models if it makes much of a difference.
