U disk two false staggering profits.

U disk two false staggering profits.

 

The industry sources, currently there are two forms of fake U disk, called "upgrade fake" (that is, the above-mentioned "upgrade products"), which simply put, is to fake low-volume U plate "to" large-capacity, but this is not just about the packaging altered, but directly on the chip in the U disk moving the hands and feet - underground factory waste sent for recycling or defective flash memory particles, minus a few capacitors while part of circuit lines, which should make a piece of silicon as a buffer force overpressure, can not be used to buffer, so that U disk buffer is occupied, the user save files are no problem, but reading does not.

 

Then again, because occupied by the buffer, so we use will not immediately discovered that the computer can show the capacity, the actual available capacity is likely to be far less. Such as the U-128M disk can be "upgraded" into 1G or 4G, the current most common form of fraud, because the most profitable, easy to turn over 100%.

 

Another fake is a direct fraud, which is affixed to sell brand-name brand when the brand can be cheaper than the real thing on about 40%, because the basic ability to use and cheap, so very easy to sell.

 

But this fake U disk speed is much slower than the real thing, the quality can not be guaranteed.
