Getting the most performance out of your SSD drive.
I had converted my machine from a magnetic platter drive to a SSD a year ago. I noticed the performance wasn’t as fast as it should be for certain operations.
My SSD was connected via IDE and I hadn’t enable my controller to support AHCI. I changed it before, but Windows 7 wouldn’t boot by default. If you installed the OS originally via an IDE drive you need to enable the AHCI driver first via the registry.
- Click Start, type regedit in the Start Search box, and then press ENTER.
- If you receive the User Account Control dialog box, click Continue.
- Locate and then click one of the following registry subkeys:
- In the pane on the right side, right-click Start in the Name column, and then click Modify.
- In the Value data box, type 0, and then click OK.
- On the File menu, click Exit to close Registry Editor.
Once that is complete go into your BIOS and change the SATA operation mode to AHCI. You will notice a pretty substantial performance increase from using the new driver.
I don’t have a SATA III 6Gbits compatible sata controller, so this is as fast as the performance will get on SATA II 3Gbits/s.
