Adding more RAM speeds up Windows and applications, allowing the system to access the hard disk less often. This is especially true for older PCs with 256 or 512 MB of RAM, and laptop computers with slow hard drives. Upgrading computer components can be costly, and is not always possible. Buying and plugging a USB flash memory stick, on the other hand, is neither expensive nor complicated. That is why MICROSOFT developed a new technology called ReadyBoost.

Using flash memory allows Windows XP to access hard drives less frequently, which results in improved performance and responsiveness of Windows XP and all applications.
