Win7 users with an Intel chipset mainboard and Intel X25-M 2G SSD's, who successfully have flashed the actually withdrawn Postville SSD Firmware, want to take advantage of the TRIM command support, but there still are some restrictions:
1. Intel's Matrix Storage Manager drivers (last official v8.9.0.1023) do not support the TRIM command. The only available SATA drivers, which do fully support the TRIM command, are the Win7 generic MS IDE/AHCI drivers.
2. SSD's running in "RAID Mode" neither do support the TRIM command nor can be "cleaned" by Intel's new SSD Toolbox.
So here is my question:
Do or will the upcoming Intel AHCI/RAID drivers of the Intel(R) Rapid Storage Technology (RST) support the TRIM command?
I ask this, because I am already running the brandnew and WHQL certified RST driver v9.5.0.1037 (available at Station-drivers since 13th October) with my 2x160 GB Intel Postville SSD RAID0 system and got a really amazing performance boost.
Thanks in advance!

Just reading into it - it would seem that these have been released 'under the radar' but only for "Desktop Boards" atm - can't confirm as I am running on a X58 Server...

The Intel RST 9.6.0 driver does support TRIM in Pass-Through mode, but not to a RAID volume.
