Once, I wrote a topic about speeding up Vista with ReadyBoost. The thing with speeding up Vista with your flash memory. For this speeding up, you don't have to plug in anything. You only need to have SATA (Serial Advanced Technology Attachment) hard disk. So, enhance your PC with this trick. Squeeze more of your PC.
NOTE: For everything you do, I (as well as CrystalXP.net) am not responsible.
How to use
1) Open Start Menu.
2) In Start Search, type Device Manager and hit Enter.

3) Expand your hard drives list
4) Right click on your hard disk and hit Properties
5) Go to Policies menu

6) Check Enable Advanced Performance (but be aware of the message bellow!!!)
7) Hit OK and enjoy 
How to Turn Off
1) Navigate back to Policies menu of your hard disk in Device Manager.
2) Uncheck Enable Advanced Performance.
3) Hit OK and you turned it off 
I hope you enjoyed this short guide about speeding up more Windows Vista
