ReadyBoost
Introduced with Windows Vista, ReadyBoost is a Windows feature that enables you to use flash media devices, such as a USB thumb drive or memory card, as super fast dedicated virtual memory.
External storage must meet the following requirements for ReadyBoost:
- Capacity of at least 256 MB, with at least 64 kilobytes (KB) of free space.
- At least a 2.5 MB/sec throughput for 4-KB random reads
- At least a 1.75 MB/sec throughput for 1-MB random writes
Some devices are pre-tested to use ReadyBoost. AutoPlay will provide ReadyBoost as an option when the device is connected. If the device is not pre-tested, ReadyBoost can be manually configured by right-clicking the device in Windows Explorer, clicking Properties, and then clicking the ReadyBoost tab.
Windows 7 can handle up to eight flash devices, while Windows Vista can only benefit from one device. Microsoft recommends using 1-3x the amount of system RAM for the ReadyBoost drives to get optimal performance.
