USB 3.0 speed is up to 5 Gbps = 625 MBps = 5000 Mbps
USB 3.0 description
USB stands for Universal Serial Bus. You can distinguish USB 3.0 or higher by blue color on the connector. You can see that your motherboard support USB 3.0 or higher by blue port and the board. Check additional motherboard specification to ensure it is compatible with the desired USB standard. USB 3.0 provides backward compatibility for slower speeds. You can use USB 3.0 in USB port 2.0 and vice versa.
USB 3.0 launched in 2008. After five years, USB 3.1 came which double bandwidth of the previous one. At that time USB-IF organization renamed USB 3.0 to 3.1 gen 1 and new established USB 3.1 to USB 3.1 gen 2.
With another USB technology leap, USB-IF organization is renaming USB names again. They are renaming 3.1 gen 1 into 3.2 gen 1. and USB 3.1 gen 2 into 3.2 gen 2. And they are adding new USB 3.2 gen 2×2 with up to 20 Gpbs.
- USB 3.0 = USB 3.1 gen 1 speed is up to 5 Gbps = 625 MBps = 5000 Mbps
- (NEW) USB 3.1 gen 2 speed is up to 10 Gbps = 1250 MBps = 10000 Mbps
- USB 3.1 gen 1 = USB 3.2 gen 1 speed is up to 5 Gbps = 625 MBps = 5000 Mbps
- USB 3.1 gen 2 = USB 3.2 gen 2 speed is up to 10 Gbps = 1250 MBps = 10000 Mbps
- (NEW) USB 3.2 gen 2X2 = speed is up to 20 Gbps = 2500 MBps = 20000 Mbps
The community response was negative. They wish the USB-IF organization came with the more simpler naming scheme. USB-IF organization never gave any official statement what the reason behind all renaming is. So when buying a new USB Flash Drive don’t look after it’s naming but rather check what speed the USB product is capable off. The reason behind this is some of the manufacturers did not go with that naming scheme. And you may find very different naming on the market for some of the same speeds.
