How to use the U disk as memory in Vista system

ReadyBoost technology is the essence of Vista operating system using flash memory as a technology, this technology in the system memory is not enough (especially when the use of 512MB run Vista), can enable large programs to start the speed has been greatly accelerated. It was developed as an assistive technology for the newest SuperFetch technology of the Vista operating system. Because the flash existence reads the random data aspect, has the unique superiority compared to the hard disk, therefore is chosen to realize the ReadyBoost function the medium.

Some friends asked, since the U disk can be used when memory, then why this technology has not been popularized? The reason is simple, not all USB flash drives support ReadyBoost, to support the ReadyBoost is very simple, this requires the Flash disk 4k file random read faster than 3.5m/ s,512k the speed of random writes is greater than 2.5m/s, the faster the better. But the current market on the common brand U disk generally can not reach this speed, not to mention those cottage U disk. But some friends may be puzzled, my U disk speed read and write speed 20 m per second, how still not, attention! That 20 m/s is the maximum reading and writing speed, not 4K files and 512K files of this small file of random read and write speed, that is the dealer cheat buyer's usual trick.

As we all know, the Hui torch u disk has been high speed, especially the small files of random read and write speed Advantage obvious. Does it support Vista ReadyBoost? Let's test it out.

1, I use the Hui torch the most commonly used 8G Flash Pocket notebook test, will fly-flash high-speed disk inserted into a good Vista system computer, the general will pop up an automatic play window.

2, click to accelerate my system, pop-up interface, in the pop-up Properties panel, select the "ReadyBoost" tab, then choose "Use this device" and "to speed up the system reservation space" (that is, choose how many U disk space as memory to use), click "OK" button, Your computer is speeding up! Because my Computer memory is 1G (has been running vista a bit hard, this is good), so I divided the 2G disk space out when memory, 3G memory should be enough to run vista it.

3, in the use of the process found in the U disk generated a 2G readyboost.sfcache file, u disk free space is also less than 2G, in the later use of the process, if you need to adjust the acceleration of u disk space, or turn off the U disk ReadyBoost function. Just open the "computer", and then the right mouse click on the U disk drive, in the pop-up menu, click the "Properties" option, you can make a variety of adjustments!

4, in the successful use of flying flash high-speed disk to achieve the ReadyBoost, I feel a bit of my vista system, the speed of the operation is very big tips, especially when running a large game, I also opened a big talk West Tour and Dungeons and Warriors, running hearty, I remember having a DNF in Vista alone.

5, in order to verify the high speed of the flash disk, I tested the hands of the Kingston 8G Flash Drive, in the choice of acceleration I found it was not successful, suggesting that the device used to speed up the system does not have the necessary performance characteristics, in fact, is not read and write speed. Lianginston are unsuccessful, not to mention the rubbish-cottage flash drive.

Of course, we use U disk when memory, the realization of ReadyBoost function has a lot of problems are to be noted, these problems will lead to obstacles in the speed, when the system memory pressure, hard disk read and write frequently, the system will be more rapid, if it is equipped with 4GB of memory, There are not a few applications running on the computer, the effect of ReadyBoost is not obvious.
