With a fast hard drive and sufficient RAM for caching, you're unlikely to notice any benefit from ReadyBoost. Adding a flash drive of 2 GB or more and dedicating it to ReadyBoost might show noticeable performance improvements in that scenario.

That combination is most likely to be found on small, portable devices popularly known as netbooks. The scenarios in which this technology is most likely to be helpful involve a combination of bottlenecks: limited RAM and a slow hard disk, possibly combined with a low-power CPU. On a modern, full-sized notebook or desktop PC that was designed to run Windows 7, chances are you'll see little or no improvement by using ReadyBoost.
And with steady improvements in hardware design since that time, it's become even more of a specialized tool.

When a supported external memory device is available, ReadyBoost caches data and program code in flash memory and is able to retrieve small chunks of that memory, when needed, more quickly than it could if it relied only on the hard diskĪlthough it got a lot of favorable press when it debuted with Windows Vista a few years ago, ReadyBoost never quite lived up to its promise. Hard disks are generally faster for large sequential reads flash drives can be quicker for small, random reads. That fact means your system can get to a given location on a flash drive more quickly than it can to a corresponding spot on a hard disk. ReadyBoost technology takes advantage of the fact that flash memory typically offers lower seek times than do hard disks with rotating magnetic media. ReadyBoost supports the exFAT, FAT32, and NTFS file systems.
Noteworthy changes include support for concurrent use of multiple flash devices and for caches larger than 4 GB. This is yet another feature introduced in Windows Vista that has been significantly improved for Windows 7. 0 flash drives and Secure Digital cards) to cache disk content of all kinds, reducing the need for time-consuming hard disk access. ReadyBoost uses external memory devices (such as USB 2.
