usb cache

The usb cache tag on WindowsForum covers the use of USB flash drives as a supplemental disk cache through Windows ReadyBoost. This built-in feature is designed to improve system responsiveness on older PCs with limited RAM and traditional spinning hard drives. By plugging a fast USB drive into a spare port, Windows can use it to cache frequently accessed data, reducing disk-access latency and making everyday tasks like launching apps, switching tabs, and opening files feel snappier. While ReadyBoost is not a performance miracle, it can provide a noticeable boost on compatible hardware. Discussions focus on practical setup, drive selection, and real-world performance expectations for users seeking a low-cost way to extend the life of older Windows machines.
