Increasing your system’s RAM can considerably improve a computer’s performance. Windows ReadyBoost allows users to temporarily increase their system’s memory without adding physical RAM to the interior of their desktop or laptop computers. ReadyBoost uses the disk cache on the USB flash drive, rather than on the internal hard drive, to increase system performance, as random disk reads are significantly faster with flash memory than with an internal hard drive. For the best performance, your USB drive should be at least one gigabyte in size and it should have at least 512 megabytes of disk space available. Warnings Writer Bio
