It'll only be faster if you're using a USB 3.0 peripheral (e.g. flash drive). Given that USB 3.0 external hard drives are more common than USB 3.0 flash drives, this won't be a benefit for most people. 99% of flash drives in people's pockets are USB 2.0, which means whether they use this cable or the normal microUSB (USB 2.0) version, they're still going to be reading and writing at USB 2.0 speeds.
