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.
