ReadyBoost

Default Description:

Provides support for improving system performance using ReadyBoost.

Additional Information:

ReadyBoost uses the Superfetch service and an USB flash drive or memory card as memory cache and performs boot optimization. If you do not use an USB flash drive in this manner, you can disable ReadyBoost, but a negitive impact on performance could result, depending upon the amount of memory installed as outline in this forum post. I recommend to leave the Superfetch service on Automatic.
