http://rog.asus.com/81692012/guides/intel-smart-response-technology-user-guide/SSD ‘Smart Response Technology’ is simply using a small SSD drive to cache system data, while still having all your files actually stored on a traditional mechanical hard drive (HDD). What that means is you get the best of both worlds: speed and capacity. Great access speeds for day to day usages via the SSD as it fills with commonly used files, and the bulk storage benefits of your traditional HDD for all your applications and files.
SSDs do not suffer from the noticeably latency that hinders mechanical hard drives as any data in their NAND Flash chips can be accessed instantly. Comparatively, just think of a HDD as an old vinyl album, where the pick up arm has to physically travel to a precise point on a particular track before it can play the song.

Installing and setting up a SSD as your system cache is simple and this guide will walk you through the process in logical steps. The first couple of steps are done in the BIOS and the reminder will be completed in your Operating System. To enable Smart SSD cache will requires that the SATA controller be set to RAID mode via the system BIOS. And that you install the
Intel Smart Response Technology which is an Intel Rapid Storage Technology (RST) caching feature. It allows a user to configure computer systems with an SSD used as cache memory between the hard disk drive and system memory.
System RequirementsFor a system to support Intel Smart Response Technology it must have the following as a minimum requirement:
Intel Z68, X79* and future 7 series Express Chipset-based desktop board
LGA 1155 or LGA 2011 Intel Core Processors compatible with the above chipset.
System UEFI BIOS with the SATA mode set to RAID
Intel Rapid Storage Technology software 10.5 version or later
Single hard disk drive or multiple drives in a single RAID volume
Solid State Drive (SSD) with a minimum capacity of 18.6GB (post format)
Operating system:
Microsoft Windows* Vista 32-bit Edition and 64-bit Edition, Microsoft Windows* 7 32-bit Edition and ... (here at ROG we always recommend Windows 7 64-bit given the choice)
*Requires an Intel driver update due 2012.
Part I: Configuring the UEFI BIOS1. Press the F2 or Delete key during boot up to enter the BIOS setup menu.

2. Go to the Advanced Tab and SATA Configuration.

3. Select the setting for SATA Mode and change the value to RAID.
4. Press the F10 and select yes to save settings and restart the system.
