Using memory in your storage device to speed up your computer
Using memory in your storage device to speed up your computer
ReadyBoost can speed up your computer by using storage space on
most USB flash drives and flash memory cards. When you plug a ReadyBoost
-compatible storage device into your computer, the AutoPlay dialog box
offers you the option to speed up your computer using ReadyBoost . If
you select this option, you can choose how much memory on the device to
use for this purpose.
When you set up a device to work with ReadyBoost ,
Windows shows you how much space it recommends you allow it to use for
optimal performance. For ReadyBoost to effectively speed up your
computer, the flash drive or memory card should have at least 1 gigabyte
(GB) of available space. If your device doesn't have enough available
space for ReadyBoost , you'll see a message telling you to free some
space on the device if you want to use it to speed up your system.
You can enable or disable ReadyBoost for a specific flash drive or other removable storage device. For more information, see Turn ReadyBoost on or off for a storage device.
Notes
-
If your computer has a hard disk that uses solid-state drive (SSD) technology, you might not see an option to speed up your computer with ReadyBoost when you plug in a USB flash drive or flash memory card. You may instead receive the message, "Readyboost is not enabled on this computer because the system disk is fast enough that ReadyBoost is unlikely to provide any additional benefit." This is because some SSD drives are so fast they're unlikely to benefit from ReadyBoost .
-
In some situations, you might not be able to use all of the memory on your device to speed up your computer. For example, some flash memory devices contain both slow and fast flash memory, but ReadyBoost can only use fast flash memory to speed up your computer.
