A brief overview of ReadyBoost® technology in Windows® 7
Windows 7 came with an enhanced version of ReadyBoost, a new tool that boots up your computer even in a low memory situation by using flash memory.
ReadyBoost uses a USB flash drive or card as memory and it works with most of the removal storage devices. In Windows 7, it can handle more flash memory and even multiple devices. When you connect a ReadyBoost-compatible storage device into your computer, the AutoPlay dialog box prompts you the option to speed up your computer using ReadyBoost. If you choose this option, you have to determine much memory on the device to use for this purpose. When you configure a device to work with ReadyBoost, Windows shows you the space recommended for an optimal performance
Here are some basic requirements in order to use ReadyBoost:
- The computer must have USB 2.0 compatibility
- The USB drive or flash must be USB 2.0 capable
- The removable media’s capacity must be at least 256 MB—250 MB after formatting.
- Windows 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.
Follow the given instructions to use ReadyBoost
1. Connect your USB flash drive or flash memory card into your PC.
2. The computer should detect the device and AutoPlay should pop-up, click on Speed up my system.
3. If AutoPlay is disabled, click on Computer, then right-click on the USB flash drive or flash memory card, and click on Properties then the ReadyBoost tab. Click the Use this device option and choose how much space you would like to associate with this device by moving the slider. You can allocate all of the memory on the device by checking the Dedicate this device to ReadyBoost, then Click OK.
Remember: Any space that is allocated for use with ReadyBoost cannot be used for saving data.
4. If at any time you would like to disable the device back for normal use, right-click on the Properties option, then the ReadyBoost tab and check Do not use this device.
Additionally, With Windows ReadyBoost, you can use non-volatile flash memory, such as that on a USB flash drive, to enhance performance without having to add additional memory.
The flash memory device serves as a backup memory cache that is, memory that the computer can use much more quickly than it can access data on the hard drive. Windows ReadyBoost counts on the intelligent memory management of Windows SuperFetch and can significantly improve system responsiveness.
