Intel® Matrix RAID ICH6R
The new ICH6R Southbridge will make its appearance with the 925X/915P chipsets on the next generation motherboards. The "R" is for RAID and this chipset will support 4 SATA hard drives and it features Intel® Matrix Storage Technology.

 This feature is able to create multiple "virtual RAID arrays" (RAID 0 and 1) to maximize space, data protection, and performance. Intel® Matrix Storage Technology combines the advantages of conventional RAID 0 and RAID 1, composing Matrix RAID with only two hard drives. You can protect your important data with RAID 1 and increase your productivity with the higher performance of RAID 0. This is a great new option for home and business users who are increasingly demanding better storage options.

Another enhanced SATA technology that is part of the ICH6R is called Hardware Accelerated Native Command Queuing. This feature improves performance by issuing multiple commands and allowing the drive itself to reorder commands based on disk organization angular position (that is to read information in the most efficient way based on where the data is stored on the disk).
