Do/will the upcoming Intel RST drivers support Trim?

@ Intel support:

It is a fact, that the Intel Matrix Storage Manager AHCI and RAID drivers do not support Trim.

So users with an Intel chipset mainboard and 1 or more Intel X25-M G2 SSD's, who had successfully flashed the Trim Firmware and now want to get benefit of the automatic Trim action while working, have to use the Win7 in-box generic MS IDE or MS AHCI drivers.

Since several weeks there are new and already WHQL certified Intel AHCI/RAID drivers v9.5.0.1037 available at Station-Drivers. They belong to the upcoming new generation of Intel storage devices support named "Intel(R) Rapid Storage Technology" (RST).

Here are my questions:

1. Do these new RST drivers v9.5.0.1037 already pass the Trim command?

2. If not, will the upcoming official release of Intels RST drivers support Trim?

3. If not, when can we expect Intel AHCI and RAID drivers, which do fully pass the Trim command?

I did already ask similar questions within another thread, but I didn't yet get an answer. That is why I started a new thread.

Thanks in advance!

9.6.0 supports TRIM in passthrough mode, but not to a RAID volume.

Yes, still no TRIM support for RAID volumes. That's why some of us aren't as excited about 9.6.0.1014 or SSD optimizer 1.3. My two X25-M SSD's are configured as a RAID1 array. Still, RST TRIM support for single drives appears to be a step in the right direction.

How do you check that the Trim command is actually functioning though? Using the "fsutil behavior query DisableDeleteNotify" command 0= trim is enabled and 1 = trim disabled right. How come I'm getting a 0 with the old 8.9 matrix storage drivers (Don't support Trim) though with my storage controller set to RAID?

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.

Ok so your're saying that Windows 7 will always show that trim is supported (0) and any other OS will show that it it isn't supported (1)? Is there a diagnostic utility out there that shows if it is working?
