Difference between 3 and 2 USB ports

[Guest]

I need to get some extra ones but not sure what is the difference between 3 and 2
Also can you recommend a 16 GB Flashdrive as I started to do the recovery programme not realising it needed a 16GB Flash, do think this should come with instructions.

USB 3 is faster. If your PC doesnt have USB 3 ports they still work, but will only bas fast as USB 2.

David recommends any SanDisk Flash Drives.

If you are upgrading your usb ports then choose USB 3.1 (released in 2013)these have allow full duplex transfer at twice the speed of USB 3 (which is 10 times the spped of USB2).
USB 3 ports etc use a blue coloured plastic to easily identify them from earlier usb designs.
