So I got an SSD yesterday and checked if TRIM is enabled, which it is. Only thing is, does Windows do it automatically? I turned defraging off for it. So how do I TRIM the SSD if Windows does not automatically do it?
After you install an SSD, in order to enable Trim, I believe the best solution is to enable AHCI mode on your PC. First, at startup type "Regedit", Open HKEY_LOCAL_MACHINE /SYSTEM /CurrentControlset / Services, then open msahci. In the field left click on "start" and click to Modify. In the value Data field enter "0" and click "ok". Exit "Regedit". Reboot the System and enter the BIOS (hold the "Delete" key while booting). In your BIOS select "Integrated Peripherals" and OnChip PATA/SATA Devices. Now change SATA mode to AHCI from IDE. Now reboot the Windows System again and the OS will recognize AHCI and install the devices. Now, the System needs reboot one more time! After these changes you will enjoy a marked improved SSD performance. On my Samsung SSD, the Read value changed from 201 to 276, the Write value changed from 219 to 244; All Read value changed from 7,232 to 26,914 and Write value changed from 14,118 to 18,922. As you can see, there were significant improvements! Steve H.
