"trim support is provided for all volume types except Raid 5 (If your ssd meets ATA-8)"
That's interesting, but it probably does not mean, that users with a RAID0 or RAID1 system will really have TRIM support, because I doubt, that the TRIM command will pass the currently available Intel RAID Controllers.

Using Win 7 (64bit), running Intel X25-M G2 in AHCI mode:
With driver v 8.9.0.1023

possibly means that having the controller set to Raid and having other standard hard drives in Raid 0, 1 or Raid 10 along with a single SSD will let the Trim commands pass through the Intel Raid Controller to the SSD.
But if the other standard hard drives are set in Raid 5, the Intel Raid Controller will not pass Trim commands to the SSD??
Definately vague - someone would have to test these configurations to see what works.

In reading the artical at: http://www.techreport.com/discussions.x/18653 http://www.techreport.com/discussions.x/18653
It seems clear that the new RST driver will support TRIM on a SSD with your controller in RAID mode as long as the SSD is not part of a RAID group. Here's the quote form the artical:
"The latest: Intel® RST 9.6 will be released this week which includes TRIM support for SSDs. It will support TRIM with SSDs in an AHCI configuration, or with the RAID controller enabled and the SSD is used as a pass through device. An example of this use case is for users that want to use the SSD as a boot drive but still be able to RAID multiple HDDs together to allow for large protect data storage – a great use for the home theater PC. TRIM support for SSDs in a RAID configuration is under investigation and is not included in Intel® RST 9.6."
So, it appears we have TRIM support with this new RST driver. The example in the artical fits my configuration exactly - I have a single boot disk and two RAID-1 HDD connected to the Intel controller and my controller is in RAID mode.

Where did you read about Trim in the RST driver help file? I was able to find this information in the "Getting Started" section of the Intel Rapid Store Technolgy Help:
Our application also provides support for the following features:
Password-protected disksThis feature provides high-level security and protection for the data on your disks with a password, denying access from any unauthorized user.Trim (Microsoft Windows 7* only)This feature provides support for solid state disks (SSDs) that meet the ATA-8 protocol requirements. This feature optimizes write operations, helps devices reduce wear, and maintains unused storage area on devices as large as possible.
