Good TRIM setup for a X25-M G2 SSD

[idata]

Appreciate any corrections/additions:

Computer BIOS set to AHCI

SSD firmware that supports TRIM:

02HA firmware or newer Have partition alignment: Create first partition with Win 7 http://forums.techpowerup.com/showthread.php?t=107126 http://sqlblog.com/blogs/kevin_kline/archive/2008/10/08/how-to-improve-application-and-database-perf...Do over-provisioning: Leave 20% of disk space as unpartitioned for controller's use http://www.anandtech.com/storage/showdoc.aspx?i=3667Use Win 7 with the following: Intel's SSD Optimizer s/w Is part of the Intel SSD Toolbox download Win 7 will use it automatically Microsoft's AHCI disk driver: msahci Microsoft's SATA controller driver: Standard AHCI 1.0 Serial ATA Controller

i got HDDErase 3.3 to work setting SATA to compatible IDE instead of Enhanced in BIOS, but it got freezed during erasing and didn't really erase anything (thanks God), but i use HDDErase 4.0 from Hiren's Boot CD 9.6 (with compatible IDE) and it worked good with my X25-M G2 SSD erasing it!

i didn't try the SSD Toolbox 'caused i had to install Windows 7 'cause Windows XP became corrupt everytime i installed Intel P55 Chipset drivers (seems they r not supposed to work with XP), so I have to wait until the new Toolbox comes out...

anyway, how to make sure Windows 7 native support works fine (with TRIM) to avoid performance degradation? what drivers should be installed, can I install Intel Matrix Storage (it comes with my mainboard)?
