U disk can really accelerate Win7 system

  
We all know that when a USB flash drive is plugged into a computer, the system will automatically ask if you need to enable u disk system acceleration, even the current Win8 system will have the same prompt. But can it really speed up? The website is compiled and analyzed by everyone. 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 not use this extra memory space to improve system performance, why not make better use of these extra memory space? The use of physical memory as a cache is the essence of SuperFetch technology. It is precisely because of this memory-based caching strategy that Vista is hungry for memory capacity! SuperFetch generally uses computer memory, which caches files in RAM. SuperFetch can also use the storage space of the U disk, in fact, this is what we call the u disk system acceleration. When you connect the USB flash drive to your computer and enable the USB flash drive system 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. Why the U disk system acceleration may not be 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. SuperFetch data must be stored on the hard disk for better results. 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. The U disk system is accelerated in the case of insufficient RAM space, and 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. Under what circumstances U disk system acceleration effect is the most significant, I really do not want to waste money to add memory, and the system's memory is only 512MB or 1GB and you happen to have a free U disk can be used. If your U disk is slow to read, then it is recommended that you do not use it. This article comes from [website] www.xxx
