What Are the Advantages of TRIM and How Can I Use It With My SSD?

What is TRIM?
TRIM is an attribute of the ATA Data Set Management Command.

The command allows the operating system to inform the solid-state drive of data blocks (such as deleted files) that can be wiped internally. This function improves compatibility, endurance, and performance.

How can I use TRIM?
Microsoft Windows 7* and Windows Server 2008* have the TRIM command enabled by default.

If you are using Microsoft Windows XP* or Vista*, the Intel SSD Optimizer identifies which files the user deleted and communicates that information to the SSD.

Note Only SSDs with drive lithography of 34nm (G2) or newer support the TRIM command. 50nm SSDs are not supported.

What are the requirements?

Will the Intel SSD Optimizer be updated to support Intel 50nm SSDs?
No. The Intel® Solid-State Drive Toolbox Optimizer tool will not work on Intel 50nm SSDs.

Is TRIM supported on RAID configuration?
Currently TRIM is not supported on RAID configurations.
