TRIM is not active without optimizer

Appreciate any corrections to the following:

Per Intel, "The Intel SSD Optimizer is the tool that implements Trim functionality."

And, since SSD Optimizer is part of the Intel SSD Toolbox, those of us with new G2 SSDs cannot utilize TRIM until the SSD Toolbox download is available.

just put "ms ahci" or "msahci" into the search field on the right up corner (Community Search) and press search. You will find all answers needed.

If you are using Windows 7, no RAID, and have the msahci.sys driver listed for your SATA AHCI controller, then running the optimizer is not needed--TRIM will function automatically.

The Intel SSD Optimizer is a tool that implements trim command. It was primarily developed for users of Windows XP and Vista OS of which know nothing about trim. Win7 has built in support to execute trim command and therefore the Intel SSD Optimizer is not needed (assuming you are using the MSAHCI driver). The one caveat today where Win7 users will have to rely upon the Intel SSD Optimizer to get trim functionality is if they are using the current Intel IMSM driver which does not support passthrough of the command. The next release of Intel's driver expected to be released by early next year will have support for trim.

From: Intel_SSD_Optimizer_White_Paper.pdf

(notice my capitalization on key words: executed and support)

Beginning of quoting.

After the Intel® SSD Optimizer has EXECUTED in Figure 2, the SSD now shares the same view of deleted files as the OS file system. Any 34nm Intel® X25-M or X18-M solid-state drives running firmware version 02HA or later will contain SUPPORT for the Intel® SSD Optimizer. When using the latest Microsoft Windows* 7 operating system with Microsoft AHCI storage drivers the OS will contain native SUPPORT to EXECUTE the Intel® SSD Optimizer on an Intel SSD without requiring any user interaction.End of quoting.

So, Intel's SSD Optimizer is required to have TRIM

This section of the whitepaper is poorly worded.

"Any 34nm Intel® X25-M or X18-M solid-state drives running firmware version 02HA or later will contain SUPPORT for the Intel® SSD Optimizer. When using the latest Microsoft Windows* 7 operating system with Microsoft AHCI storage drivers the OS will contain native SUPPORT to EXECUTE the Intel® SSD Optimizer on an Intel SSD without requiring any user interaction."

Replace "Intel SSD Optimizer" with "Trim" and it will read correctly. Table 1 in the whitepaper is accurate in detailing when you need to use the Toolbox/Optimizer to get trim support. The ONLY time you need the Toolbox/Optimizer to get trim suport in Win7 is when using Intel Matrix Strorage Driver. If using MSACHI driver Win 7 will automatically do the trimming for you.
