Once you move into RAID 0 with a pair of SSD drives it is nothing but smiles. Here is my current benchmark on 2 Corsair Xtreme 256 on Raid 0.
Here's what Intel said before the update hit the web last Friday:
"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".
Translation: if your Intel storage controller is set to RAID mode, you'll now be able to benefit from your solid-state drive's TRIM functionality when running it alongside a RAID array comprised of mechanical drives. TRIM isn't supported for SSDs participating in a RAID array, however. Intel may add that feature in the future, but it hasn't committed to doing so.
The way RAID works, you could never add TRIM support to a RAID device unless the controller itself supported trim on it's devices. What Intel did was merely configure the raid driver to support SSDs and present them to the OS without virtualizing the device so TRIM support in the OS could do it's thing.
