U disk for system acceleration - U disk for WIN7/WIN8 system acceleration

The concept of U disk system acceleration was introduced from the Vista system. At that time, it was a new feature that Microsoft promoted. However, it certainly does not significantly speed up your system as much as directly increasing the machine configuration, but it is certainly useful in some specific situations.

U disk acceleration works

U disk acceleration assists from SuperFetch (super pre-read) to work. SuperFetch is also a new technology introduced at the time of Vista's launch. The system will be able to automatically record the occurrence and end time of the regular operation behavior according to the user's usage habits. At the time, the foreground and background software running at the time, etc., will be automatically pre-stored in the hard disk when there is free space in the memory. The swap file is converted to a memory page, which speeds up the program when the user runs frequently.

The central idea of ​​SuperFetch technology is: "Excessively empty memory space is a waste”. Indeed, if an operating system
always retains too much free physical memory power, but can't use this extra memory space to improve system performance, why not make better use of this extra memory space? What? Using these extra physical memory as a cache is the essence of SuperFetch technology. It is also because of the use of this memory-based cache strategy, which caused Vista to hungry for memory capacity!

SuperFetch generally uses computer memory, which caches files in RAM. SuperFetch can also take advantage of the storage space of the USB flash drive. In fact, this is what we call the u disk system acceleration. When you connect the USB flash drive to the computer
and enable the USB flash drive to speed up this function, the system will store the SuperFetch data in your USB flash drive and release the system memory. Reading cumbersome small files from a USB flash drive is faster than reading from a hard disk, so in theory, this can improve your system performance.

How to use U disk to accelerate

Whenever you insert a USB flash drive into your computer, the system will automatically ask you if you need to enable u disk system acceleration, even the current Win8 system will have the same Tips. If you don't have a computer, you can find it in the following figure:

But do you understand the U disk system acceleration? Does the U disk system speed up this function can really speed up the Windows
Running speed.

Why is the U disk system acceleration not suitable for your computer?

So far, we have only seen the advantages of U disk system acceleration. But the U disk has a hard flaw, that is, the USB storage speed is definitely slower than the RAM. The SuperFetch data must be stored on the hard disk better. Therefore, the U disk system acceleration is only the most obvious when your RAM space is insufficient. 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 ideal. At the time of the release of Vista, the official test used 512MB of RAM, plus the use of U disk system acceleration technology, the effect is very good. But now, the computers you use usually have a few GB of RAM. Adding extra RAM is always possible for improving computer performance.

If your computer is running and the memory is already stressed, then you'd better replace it or add an extra memory stick to solve the problem.

When is the U disk system acceleration effect most significant

I really don't want to waste money to add memory, and the system's memory is only 512MB or 1GB and you happen to have free U The disk can be used. If your U disk is slow to read, then it is recommended that you do not use it.
