Windows defaults to write-behind caching, holding data in a memory
buffer before writing it to disk. Disabling this function will increase
your system performance by writing data immediately to disk. To disable
this function, right click on My Computer and choose Properties, or
open Control Panel and select System. Select the Hardware tab and click
the Device Manager button. Click the plus sign next to Disk Drives and
select a drive. Choose Properties and uncheck Write Cache Enabled.
Repeat for all drives in your system
