The Trim command should be enabled by default on Windows 7, but if you want to check to make sure do this:


Command prompt > fsutil behavior query disabledeletenotify

DisableDeleteNotify = 1 (Windows TRIM commands are disabled)
DisableDeleteNotify = 0 (Windows TRIM commands are enabled)

quick and dirty explanation, defrag/disk cleanup for SSDs that support it. Refreshes the disk to keep its speed, without having to wipe data off the drive.

Kinda sorta. Without getting into too much, TRIM is a function of the OS where it sends the TRIM command to the SSD controller to clear blocks of data which are no longer being used (when a file is deleted for example). This is done during idle time so as to not impact performance. NAND laundering (aka garbage collection) is basically performs a defrag. I'm nto 100% sure but I don't believe NAND launderer is a function of the OS but is triggered by the user using the software tool provided by the manufacturer. Also, TRIM is only supported by the newer SSD's (most requiring firmware updates) and certain OS's like Win 7 and some Linux distros.

is there a way to see if its supported? I ran the command and it came up 0, but how do i know if the SSD supports TRIM? or is this a stupid question?

Check with the manufacturer...which drive do you have and what firmware version? I can probably tell you.

Which drive model and manufacturer? OCZ and Intel are pretty much the only 2 supporting TRIM on some drives. I think Corsair has or will be releasing firmware updates very soon to do so and Patriot, well who knows because they aren't saying anything.
