First verify your SSD is set up properly
Down load AS SSD, run, look in uper left for Proper driver and partition alignment.

To verify trim is enabled: From a Cmd prompt (Must right click and select Admin privilage. fsutil behavior query DisableDeleteNotify

To set: fsutil behavior set disablenotify 0.

Regroup - May be a dumb question but, what operating system. Everyone, including myself, are taking for granted that this is a windows 7 installation. If NOT windows 7, then there is NO trim cmd.

If win 7 was installed properly, then Trim would be enabled automaticly in windows 7.
Will post back on how to verify.

Two things you can check in registry:
"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters", and if "EnablePrefetcher" & "EnableSuperfetch" was 0 it meant TRIM be working.

Also look at Defrag, your SSD should NOT be listed.

Added - From cmd promp started with Admin Privilage - type "fsutil /?" That should show if you have the cmd. If windows 7 and you get an error mesage then a problem with windows installation.

Hello,

Do you have AHCI enabled in the BIOS? If you are currently in IDE mode in the BIOS here's how to do the switch AHCI needs to be enabled in the BIOS to enable TRIM command:

Or if you feel like you want to do some registry editing (note this is the same fix as above).

Please read the instructions first before proceeding if you are currently in IDE mode.

I sure hope the OP is using win 7 or else he's posting in the wrong group.

@ Hawkeye22 - Yea, My bad, didn't read the Heading close enough.

Do you have a prefetch folder in Windows directory??

For registy, start regedit and do a search for "PrefetchParameters"
