Have you recently purchased and cloned your old HDD with a new SSD? Here’s some tips. (Updated!)
- Make sure your SATA controller is set to AHCI mode.
Set AHCI mode in the BIOS if this is not enabled and make changes to the registry (first)
AHCI is needed for native TRIM support in Windows 7. This allows TRIM to do its job
- Click on the Start
- Control Panel
- Device manager
- IDE ATA/ATAPI controllers
- Do you see the AHCI controller?
How do you enable AHCI?
Before doing the process below, see if your BIOS has AHCI capabilities (Windows 7)
- Open Registry Editor and move down to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\msahci.
- Right click on the Start DWORD and click on Modify.
- Set the value to 0 and click OK.
- Reboot your computer and enable the AHCI setting the BIOS. Another restart will be required to finish the driver installation.
The next step is to enable TRIM. Type the following command in a command prompt to enable TRIM:
fsutil behavior set disabledeletenotify 0
Next, turn off Defragmentation. These drives should not be defragged.
Next, turn off indexing. This causes unnecessary writes.
Next, Click on Start -Right-Click Computer – Manage – Services and Applications – Services -Right-Click Windows Search – Properties Find the Startup type – Select Disabled – Click OK.
(The above disables the “search indexer”)
Click on Start – Computer – Right click on your SSD – Properties – Uncheck Allow files on this drive to have contents indexed in addition to file properties – Click OK.
- Right Click on Computer and select Manage
- Click on Device Manager
- Expand Disk Drives
- Right click on the hard drive and select Properties for that hard drive (you can also double click the drive
- On the Policies tab:
Check Turn off Windows write-cache buffer flushing on the device
- Hit OK and close the Device Manager
Next, if you have 6 GB of RAM or more, disable the page file.
Click on Start Menu – Right-Click Computer – Properties – Advanced System Settings – Advanced Tab – Performance Settings – Advanced Tab – Click Change under Virtual Memory – Uncheck Automatically manage paging file size for all drives – Click on No paging file – Click Set – OK – Restart your computer. (Always check your pc to see if the 6 GB or more is OK. This will be based on programs that are running)
