Increase SATA Disk Drive Performance In Windows Vista

You can squeeze a more performance out of your SATA hard disk drive by enabling write caching. The price though, is an increased risk for data loss/corruption should you experienced a power loss - this risk is less in a laptop because of its battery:
1. Click on the Start Button, enter Device Manager and hit Enter.

2. Expand Disk Drives.

3. Right-click on your hard disk drive and select Properties.

4. On the Policies tab, check Enable Advanced Performance.

5. Click OK and close Device Manager.
