ReadyBoost

Get extra memory in a flash with ReadyBoost—watch this video to see how. (0:39)

Want a simple way to speed up your PC?

Just plug in a USB flash drive or card and let ReadyBoost borrow it. ReadyBoost is designed to help when your PC's memory is running low. Low memory can make your computer sluggish because Windows, which needs a place to stash data, turns to the hard drive. Flash memory offers a speedier alternative.

ReadyBoost works with most flash storage devices. In Windows 7, it can handle more flash memory and even multiple devices—up to eight, for a maximum 256 gigabytes (GB) of additional memory.
