Hi friends, Windows 7 and Windows vista comes with a ready boost option. Q-What is ready boost
Ans- "ReadyBoost is a disk cache component of Microsoft Windows, first introduced with Microsoft'sWindows Vista in 2006 and bundled with Windows 7 in 2009. It works by using flash memory, a USB flash drive,SD card, CompactFlash, external hard drive
or any kind of portable flash mass storage system as a cache. ReadyBoost is also used to facilitate SuperFetch, which allows it to perform analysis of boot-time disk usage patterns and creates a cache which is used in subsequent system boots." Source
