Windows Vista has built I support for improving the performance of SATA hard rives but by default these performance settings are disabled.
You can enable this performance option from the Device Manager. Open the run command window and type “devmgmt.msc”.
You can also access the Device Manager by typing device into the search box.
Once the Device Manager window appears, expand the disk drives and select the SATA drive.
Choose Policies tab and tick the “Enable write caching on disk” option. Also, tick the “Enable advanced performance” option.
Press OK to confirm the changes.
