Understanding the Speed Performance of the USB 3.0

The creation of the USB system back in the mid 90s has really put as a step forward in data transmissions and communications between the PC and the connected peripherals. Through USB data transfers, information can be much more efficiently transmitted between the host PC and the devices. In addition, the implementation of this interface has provided users with a much easier way of connecting additional devices to one’s computer. With the previous approach, one had to make sure that one was using the right serial port to connect the device while with USBs all ports are basically the same.

Although USBs do provide a faster and more efficient way of being able to transmit data that still doesn’t really mean that it can really blow you away with its performance. The USB 2.0 interface still really isn’t that fast and with certain computer systems data transfers can be an issue with its speed and thus the time it takes to accomplish it. Users of these computer systems tend to avoid using the USB interface when it comes to transferring large files of data. The only use USBs have for them would be with the mouse and keyboard. However, with the development of the USB 3.0, things might just really take a turn for the better.

Times really have changed and this has brought with it the improvement of technology including the USB 3.0. With the availability of the new version of the USB interface, users with computer systems that did not do that well with USB data transfers in the previous version of the USB now have hope with a version that is supposedly a lot faster than its predecessor.

The USB 3.0 which is also called the SuperSpeed USB is said to have a max bandwidth of five gigabits per second. That can be translated into six hundred forty megabytes per seconds which is actually a lot faster than its predecessor the USB 2.0 or the Hi-Speed USB, ten times faster to be more specific.

But the question is does the USB 3.0 really live up to its hype? Well the only way to really check is to put the SuperSpeed USB to the test with its data transfers. With the hard drive tests, the USB 3.0 performed pretty consistently. Whether it was writing a 10 GB file, reading a 10 GB file, writing a 10 GB folder, reading a 10 GB folder, writing AJA, or reading AJA, the SuperSpeed USB showed a range of 112 megabytes per second to 115 megabytes per second.

With SSD tests, USB 3.0 performed quite significantly better having a range of 114 to almost 200 megabytes per second with all of the six tests that we used. Meanwhile the USB 2.0 just couldn’t keep up with only 41.3 megabytes as the fastest USB data transfer.

We conclude that USB 3.0 really is faster than its predecessor, the USB 2.0. However, you will not be able to see the ten times faster speed with the new interface. The fastest that we were able to get was three times than 2.0 but still it is quite an improvement.
