U disk to the WIN7/WIN8 system acceleration is really feasible?

Whenever you insert a U disk into the computer, the system will automatically ask you whether you need to enable the U-Disk system acceleration, even now the WIN8 system will have the same hint, but you understand the U Disk system acceleration, u disk System to speed up this function is really can significantly speed up the speed of Windows.

U Disk System Acceleration This concept is introduced from the Vista system, at that time, that is Microsoft vigorously promote a new function. However, it certainly does not speed up your system as dramatically as the machine configuration, but it is certainly useful in certain situations.

U disk speed up the working principle

U-Disk accelerates assistance from SuperFetch (super Pre-read) to work. SuperFetch This technology is also introduced in Vista when the introduction of new technology. The system will be able to according to the user's use habits, automatic record of the regular operation of the occurrence and end of the time, then run the foreground and background software and so on details, then in the existence of free space, automatically in advance will be stored in the hard disk of the exchange file into the memory page, Speed up the startup of programs that are frequently run by users.

The central idea of SuperFetch technology is that "excessive spare memory space is waste". Indeed, if an operating system always retains too much free physical memory to consume electricity, but cannot use these extra memory space to improve system performance, why not make better use of these extra memory space? Using these extra physical memory as a cache is the essence of superfetch technology. And it is because of the use of this memory-caching strategy, which caused the Vista on the memory capacity of hunger!

SuperFetch typically uses the computer's memory, which caches files in RAM. SuperFetch can also use U disk storage space, in fact, this is what we call the U-disc system acceleration. When you connect the U disk to the computer and enable the U disk system to speed up this function, the system will be superfetch data into your USB drive and release the system memory. Reading cumbersome small files from a USB disk is faster than reading from a hard disk, so in theory this can improve your system performance.

　　Why is it that the USB drive system acceleration may not be suitable for your computer

So far, we have only seen the U disk system to accelerate the advantages. But the U disk has a mishap is the USB memory speed is sure to be slower than RAM, SuperFetch data must be stored on the hard disk the effect is better. Therefore, the U Disk System acceleration only if you have insufficient RAM space in the case of the most obvious effect. If your RAM space is large enough, then the U-Disk system acceleration is obviously meaningless.

U Disk System acceleration in the case of insufficient RAM space, the effect is more ideal. In the original Vista just released, the official test using 512MB RAM, plus the use of U Disk System acceleration Technology, the effect is very good. But by now, the computers you use usually have a few gigabytes of RAM. Adding additional RAM is always feasible for improving the performance of the computer.

If your computer is running with memory pressure, it's best to replace or add extra memory strips to solve the problem.

　What is the most significant acceleration effect of u disk system?

Oneself really do not want to waste money to add the memory, and the system's memory only 512MB or 1GB of the case and you happen to have free u disk can be used. If your USB disk is slow to read, it is recommended that you do not use.
