Host Controller: NEC Electronics USB 3.0 Host Controller v1.0.18. PC: Motherboard GIGABYTE GA-P55-UD4, CPU Intel Core i5 750 2.67GHz, 4GB DDR3 RAM, Windows 7 What this means is that as soon as any of these factors change, the results will likely change as well. Note that the benchmark includes a detailed list showing the host computer, the hard drives and even the software that was used in the test. If the WD external hard drive still owns a slow transfer rate, try the other fixes as shown below. If the speed is normal now, congratulations and you can stop here. Now, you can try to copy and transfer data between your computer and external disk again. The actual data transfer rates may vary for many reasons.įollowing is an example of a benchmark that shows the actual transfer speed. Plug the external hard disk to PC via the USB 3.0 cable and USB 3.0 port. When measuring the actual time it takes to transfer data from the computer to the external hard drive or vice versa, in some cases, the result will be close to the theoretical value but for now, with USB 3.0, in many cases it will be quite a bit less. However, there are no HDDs which can handle that speed. That should allow for around 500MB/s transfer at best.
