I have not seen any RAID information for SATA systems.
First, does the motherboard manufacture have a RAID driver for the SATA interface?
If not, you are going to need to identify the SATA controller and see if the controller manufacture offers a RAID driver.
Next, you will need 2 or more identical SATA hard drives. The number of drives needed depends on the level of RAID that you wish to use, and the amount of storage capacity you need.
Like ALL RAID systems, the drive controller must be RAID enabled, and you need to install a RAID driver.
Check the specifications for the motherboard. If they do not mention RAID, you will need a 3rd party SATA RAID controller to implement RAID on your PC.
Thanks Chas. What I really needed to know was how it works and for what purpose. I am building a system with an Intel D875PBZLK Socket 478 MB. The board stats claim SATA (1.5Gb/s) Hard Drive Support with Intel RAID Technology. I'll use the links that you provided to learn more about RAID. Thanks again. I've got four 40 Gb/s WD 10,000 Rpm Hard Drives. I am concerned with access speed as well as data protection.
