USB 3.0
The days of the old USB 2.0 standard are numbered with motherboard manufacturers and other PC related hardware makers starting to adopt the USB 3.0 standard. It does everything that a version 2.0 device/port can do except for one single fact, it can offer up to 100 watts of power on the port.
More juice allows faster charging for usb gadgets and more power for other peripherals you attach to your PC. This has been a major problem for USB gadgets like external drives that do need a lot of power when you plug it in. To get them going, you need a separate USB hub with it’s own adapter but the new standard would eliminate that. You may have to lessen your tinkering a bit with those USB gadgets for 100 watts can be a whopper indeed.
