Pretec USB flash drive is following the industrial standard to test the transfer rate. Our test is under the standard of simplest condition and general accepted benchmark. In the case of usual transfer, the speed will be limited by related hardware and software to reach the expected speed. These factors include:
(1)Motherboard (Driver, Firmware)
(2)The number and format of transferring data Operating System (Version)
(3)Related hardware ( i.e. USB cable, memory and so on)
All of these factors would be slowing down the transfer speed.
