The USB Key has to have at least 230mb of free space.The device must be able to do 3.5 MB/s for 4 KB random reads uniformly across the entire device and 2.5 MB/s for 512 KB random writes uniformly across the device.Hard disks are faster for large sequential reads flash disks are quicker for small, random reads. Essentially that means that your system can get to a given location on a flash disk more quickly than it can to a corresponding spot on a hard disk. ReadyBoost takes advantage of the fact that flash memory offers lower seek times than hard disks. Clicking on the latter lets your USB drive act as a ‘scratch-pad’. As soon as you plug it in, you get a popup screen asking you to open the files or to ‘speed up the system’. So the ReadyBoost feature lets you use a USB drive (or any of the three above) instead. But hard drives are much slower than memory cards. Normally Windows uses a portion of your hard disk as a sort of a scratch pad, writing temp data to it while it works.
Windows supports the following form factors for ReadyBoost: With this feature, you can speed up your PC with a USB memory. If the data is not found in the ReadyBoost cache, it falls back to the HDD. Please note that this does not put the paging file onto a flash disk the file is still backed on disk this is a cache. In a way, Ready Boost for hard drives already exists in the form of Page files. Windows Vista introduced a feature called ReadyBoost.
