How to Use Windows ReadyBoost
Here's how to use Windows ReadyBoost:
1. Insert a flash drive or memory card into an available slot on the outside of your PC.
2. Wait while Windows Vista checks to see if the device can perform as memory. Note:
- The USB Key must be at least USB 2.0
- 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
- The USB Key has to have at least 64mb of free space
3. If prompted to use the flash drive or memory card to improve system performance, click Speed Up My System. A prompt for a flash drive and a prompt for a secure digital storage device are shown. [See Image1] [See Image 2]
4. Open Computer, and right-click the new icon for the hardware. Choose Properties.
5. Define how much of the device's memory to use for performance, and how much to use for file storage. [See Image 3]
If the device isn't fast enough to serve as a ReadyBoost memory cache, you'll see the message here. You can opt to never test this device again if desired. [See Image 4]
Important: ReadyBoost only offers performance enhancements when and if you run over your current RAM buffer. That's because when your PC has used all of the RAM it has access to, it sends the excess data it needs to cache to a paging file on the hard drive. Since the hard drive has to spin to write and read data and ReadyBoost memory does not, performance is enhanced.
