USB 3.1 Gen1 is just a fancy name for USB 3.0, which provides speed up to 5Gbps while USB 3.1 Gen 2 is another name for USB 3.1 which provides a speed of 10Gbps.
Should I buy a USB 2.0 or 3.0 flash drive?
The USB 2.0 standard offers a theoretical maximum signaling rate of 480 megabits per second, while USB 3.0 defines a maximum rate of 5 gigabits per second. In other words, USB 3.0 is theoretically more than ten times faster than USB 2.0. If the comparison ended here, upgrading would be a no brainer.
Does USB 3.0 need a special cable?
To get USB 3.0 speeds, you need special USB 3.0 cables. … Even though you can connect a USB 3.0 device via a USB 2.0 cable, in order to achieve full USB 3.0 speeds you need to rewire any existing cabling.

How many wires does USB 3.0 have?
10 wiresThe USB 3.0 specification calls for a total of 10 wires plus a braided outer shield. Two wires are used for power. A single unshielded twisted pair (UTP) is used for High-Speed and lower data transfer and allows for backward compatibility.
What happens if you plug a USB 2.0 into a USB 3.0 port?
You can plug a USB 2.0 device into a USB 3.0 port and it will always work, but it will only run at the speed of the USB 2.0 technology. So, if you plug a USB 3.0 flash drive into a USB 2.0 port, it would only run as quickly as the USB 2.0 port can transfer data and vice versa.
Will USB 3.0 work on older computers?
Are 3.0 USB ports backward compatible? USB connections are backwards compatible. That means older versions will work with new versions, but they’ll only work at their original speed. For example, if you connect a USB 2 hard drive to a USB 3 port, the transfer rate will be USB 2 speeds.
Will a USB 3.0 cable work in a USB 2.0 port?
USB 3.0 cables can be used with 2.0 devices and ports if the connector types fit (no B Male or B Micro connectors) but the transfer rate will fall back to 2.0.
