What is ReadyBoost
ReadyBoost is a feature of Windows Vista and Windows 7 and windows 8 that uses a USB flash drive for caching. This allows Windows Vista or Windows 7 to service random disk reads with performance that is typically 80-100 times faster than random reads from traditional hard drives.
For a USB flash drive to be compatible, it must conform to the following requirements:
The device should have an access time of 1 ms or less.
The capacity of the USB flash drive must be at least 256MB (250 after formatting).
The device must be capable of 2.5 MB/s read speeds for 4 KB random reads spread uniformly across the entire device and 1.75 MB/s write speeds for 512KB random writes spread uniformly across the device
The device must have at least 235MB of free space
ReadyBoost supported features/capacity:
On Windows Vista, the largest cache file size is 4GB
On Windows 7, the largest cache file size is 256GB (can span up to 8 flash drives).
NTFS, FAT32 and exFAT are supported.
The recommended amount of flash memory to use for Windows ReadyBoost acceleration is one to three times the amount of random access memory (RAM) installed in your computer.
To turn ReadyBoost on or off
Plug a flash drive into your computer.In the Autoplay dialog box, under General options, click Speed up my system.
In the Properties dialog box, click the ReadyBoost tab, and then do one of the following:
To turn ReadyBoost off, click Do not use this device.
To use the maximum available space on the flash drive for ReadyBoost, click Dedicate this device to ReadyBoost. Windows will leave any files already stored on the device, but it'll use the rest to boost your system speed.
To use less than the maximum available space on the device for ReadyBoost, click Use this device, and then move the slider to choose the amount of available space on the device you want to use.
Click OK.
