Intel retracted that statement.although the home-use scenarios of RAID 0 or RAID 1 are well covered
This is reportedly from IntelIs there TRIM support for RAID configurations?
Intel® Rapid Storage Technology 9.6 supports TRIM in AHCI mode and in RAID mode for drives that are not part of a RAID volume.
A defect was filed to correct the information in the Help file that states that TRIM is supported on RAID volumes.
Is Trim working?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.
This is suppose to tell you if Trim is actually working.The Win7 command "fsutil behaviour query DisableDeleteNotify" command only shows, if TRIM actually is supported by the OS, but does not certify, that TRIM really is working.

EDIT:
I found a MS Windows 7 article on SSD support. It's kinda long but the FAQ sections answers a lot of questions about the SSD setup defaults in Windows 7.
Engineering Windows 7 - Support and Q&A for Solid-State Drives
There’s a lot of excitement around the potential for the widespread adoption of solid-state drives (SSD) for primary storage, particularly on laptops and also among many folks in the server world. As with any new technology, as it is introduced we often need to revisit the assumptions baked into the overall system (OS, device support, applications) as a result of the performance characteristics of the technologies in use. This post looks at the way we have tuned Windows 7 to the current generation of SSDs. This is a rapidly moving area and we expect that there will continue to be ways we will tune Windows and we also expect the technology to continue to evolve, perhaps introducing new tradeoffs or challenging other underlying assumptions. Michael Fortin authored this post with help from many folks across the storage and fundamentals teams.
In Windows 7, we’ve focused a number of our engineering efforts with SSD operating characteristics in mind. As a result, Windows 7’s default behavior is to operate efficiently on SSDs without requiring any customer intervention. Before delving into how Windows 7’s behavior is automatically tuned to work efficiently on SSDs, a brief overview of SSD operating characteristics is warranted.
