How to Speedup windows vista and improve windows vista performance using ReadyBoost

Ready Boost is a disk caching technology first included with Microsoft's Windows Vista operating system. It aims to make computers running Windows Vista more responsive by using flash memory on a USB 2.0 drive, SD card, Compact Flash, or other form of flash memory, in order to boost system performance.

ReadyBoost is also used to facilitate SuperFetch, an updated version of Windows XP's prefetcher which performs analysis of boot-time disk usage patterns and creates a cache which is used in subsequent system boots.

How to enable the ReadyBoost to speed up your vista?

1.Select the USB drive and right click and select properties
2.You can see the option enable or disable it select enable
and set recommended ReadyBoost cache 1:1

For a device to be compatible and useful it must conform to the following requirements:

* The capacity of the removable media must be at least 256 MB (250 after formatting)
* Devices larger than 4 GB will have only 4 GB used for ReadyBoost
* The device should have an access time of 1ms or less
* 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 512 KB random writes spread uniformly across the device
* The device must have at least 235 MB of free space
* NTFS, FAT16 and FAT32 are supported
* The initial release of ReadyBoost supports one device
* The recommended amount of memory to use for Windows ReadyBoost acceleration is one to three times the amount of random access memory (RAM) installed in your computer

Performance
A system with 512 MB of RAM (the minimum for Windows Vista) can see significant gains from ReadyBoost. In one test case speeding up an operation from 11.7 seconds to 2 seconds (increasing physical memory from 512 MB to 1GB reduced it to 0.8 seconds). Systems with 1 GB or more do not show a significant effect on tests to date.
