Now the U disk is generally 8G, 16G, write speed is relatively inadequate, now introduce a method for you, you can modify the system to greatly improve the performance of the U disk under Windows 7.
This approach is similar to what we know about improving the performance of SATA hard drives, which is to turn on the advanced write cache (Advanced write caching), which, when modified, increases the capacity of the system memory as a write cache, thereby enhancing the performance of the write disk. However, it does not allow you to plug a 8G size of a U disk faster, but to make the U disk to other system processes faster response speed, for the U disk Transmission of a large number of small files or on a USB flash drive to run an application in the case of improved performance.
The method is actually very simple, first open Device Manager, and then open the "Disk" list, you can see the system connected to each disk, including your USB drive. Right click on the USB drive, select "Properties", open the "Policy" tab, you can see two options, one is to optimize the fast removal (Optimize for quick removal), one is optimized performance (Optimize for performance), Choose the one below to do it.
Click OK to restart after the entry into effect, it is important to note that this change is not driven by the U disk but kept in this computer, if you insert a U disk into other computers, you need to set up on this computer.
