Speed up your PC’s performance.

Windows Vista introduces a new concept for adding additional performance to a running system. Windows ReadyBoost™ lets people use flash memory on a USB
2.0 drive, SD Card, Compact Flash, or other memory form factor to provide additional memory cache—memory that the computer can access much more quickly than it can
access data on the hard drive. Insert a USB 2.0 memory drive with at least 512 MB capacity. When prompted, click use this device to speed up my computer.
