What is ReadyBoost in Windows?
ReadyBoost is a way to use most kinds of flash memory (PAN drive, SD Card etc) to help speed up your system by using it in addition to your physical memory as disk cache. Basically, it is almost like adding more RAM on-the-go without having to crack open your PC case and install it. The feature uses a technology called Superfetch which basically pre-loads information for applications enabling them to start-up more quickly than usual. This is capable because it frees up physical memory and because flash memory can read-write faster than a hard drive.
Plug in your USB flash drive or flash memory card into your computer. ReadyBoost is designed to help when your PC's memory is running low. Low memory can make your computer sluggish because Windows, which needs a place to stash data, turns to the hard drive. Flash memory offers a speedier alternative.
ReadyBoost works with most flash storage devices. In Windows 7, it can handle more flash memory and even multiple devices—up to eight, for a maximum 256 gigabytes (GB) of additional memory.
The removable media’s capacity must be at least 256 MB—250 MB after formatting.
Vista only allowed less than 4GB of memory for ReadyBoost, but Windows 7 allows up to eight devices for a maximum of 256 GB of additional memory.
