This obviously messes up with whatever content might be on SSD already (and partition table, etc), so effectively RST purges all the files from SSD (there is no option to save existing data) and creates new empty volume for data.
It would be a bit tricky to do perform this process when you have got live OS on this SSD already
However, they should make an option to reserve and create cache volume on SSD available on pre-boot Options ROM (like regular RAID 0,1,5 etc volumes). Maybe in future firmware update (yeah, wishful thinking...)
You really need to read anand article on z68 and smart cacheing. May I ask what performance level you have Smart Cache(SRT) set at , 2 choices.
This is from the intel rep who post here now and again!
Intel® Smart Response Technology User Guide
Note: This feature requires that the SATA controller be set to RAID mode via the system BIOS.
Intel® Smart Response Technology is an Intel® Rapid Storage Technology (RST) caching feature that
improves computer system performance. It allows a user to configure computer systems with an SSD
used as cache memory between the hard disk drive and system memory. This provides the advantage of
having a hard disk drive (or a RAID volume) for maximum storage capacity while delivering an SSD-like
overall system performance experience. Intel® Smart Response Technology caching is implemented as a
single drive letter solution; no additional drive letter is required for the SSD device used as cache.
For a system to support Intel Smart Response Technology it must have the following:
Intel® Z68 Express Chipset-based desktop board
Intel® Core™ Processor in the LGA 1155 package
System BIOS with SATA mode set to RAID
Intel Rapid Storage Technology software 10.5 version release or later
Single Hard Disk Drive (HDD) or multiple HDD’s in a single RAID volume
Solid State Drive (SSD) with a minimum capacity of 18.6GB
Operating system: Microsoft Windows* Vista 32-bit Edition and 64-bit Edition, Microsoft Windows*
7 32-bit Edition and 64-bit
Configure SATA Mode in BIOS Setup
1. Press the F2 during boot up to enter the BIOS setup menu
2. Go to Configuration > SATA Drives
3. Select the setting for Chipset SATA Mode and change the value to RAID
4. Press the F10 key to save settings and restart the system.
Operating System Installation
5. You may now begin installation of the operating system on the HDD (or RAID volume)
6. Install all required device drivers
7. Install the Intel Rapid Storage Technology software version 10.5 or later
Enabling Intel Smart Response Technology
Note: The Intel RST software denotes Intel Smart Response Technology as Accelerate
8. Run the Intel RST software through the All Programs menu or the task bar icon.
9. Click “Enable acceleration‟ either under “Status‟ or “Accelerate‟.
10. Select the SSD to be used as a cache device.
11. Select the size from the SSD to be allocated for the cache memory.
Note: Any remaining space on the SSD may be used for data storage using the simple data
single-disk RAID 0 volume that is automatically created.
12. Select the HDD (or RAID volume) to be accelerated. It is highly recommended to accelerate the
system volume or system disk for maximum performance.
13. Select the acceleration mode, and then click “OK‟. By default, Enhanced mode is selected.
Note: Enhanced mode (default): Acceleration optimized for data protection.
Maximized mode: Acceleration optimized for input/output performance.
14. The page refreshes and reports the new acceleration configuration in the Acceleration View.
15. Congratulations! Your system is now successfully configured with the Intel Smart Response
