While shopping for a dual USB drive, you may have seen reference to USB 3.0. USB 3.0 is one of the latest USB versions to be released and it can offer data transfer speeds up to 10x faster than USB 2.0, especially useful for large groups of files or bigger files, like videos. However, to get the full benefit of USB 3.0, both the host device and peripheral device must be USB 3.0. For example, if you have a newer laptop with USB 3.0 ports, you could take advantage of the faster speeds by buying a USB 3.0 dual USB drive. But if you have older USB 2.0 ports, you will not get the same benefit by buying a USB 3.0 dual USB drive. Before purchasing a dual USB drive, check the USB ports you wish to use it with.
