The USB net / gross data rate and description of the USB 3.0 technology!

3.) ... The USB technology and data rates!
4.) ... More related tips on data rates and Co.!




1.) The USB data rates!

In bytes per second:
NET GROSS
USB 1 1.0 MB / s 1.5 MB / s
USB 2 40 MB / s 60 MB / s
USB 3 300 MB / s 625 MB / s
USB 3.1 900 MB / s 1.25 GB / s
USB 3.2 1800 MB / s 2.50 GB / s
USB 4.0 3600MB / s 5.00GB/s


In bits per second:
NET GROSS
USB 1 8.0 Mbit / s 12 Mbit / s
USB 2 320 Mbit / s 480 Mbit / s
USB 3 2400 Mbit / s 5 Gbit / s
USB 3.1 7200 Mbit / s 10 Gbit / s
USB 3.2 14400 Mbit / s 20 Gbit / s
USB 4.0: 28800Mbps / s 40 Gbit / s

2.) Why is it not always possible to achieve USB data rates?

But be careful!

The whole thing only works if all drivers are correct and all components take part in this data transfer.

An example, you have a USB 3 hard drive that is 300 MB / s, but only if the hard drive is 300 MB / s this is only the case with SSD, usually 2.5 inch hard drives 100-150 MB / s 3.5 inches 150-200 MB / s and that again only when writing sequentially on the hard drive.     

3.) The USB technology and data rates!

Description of the USB 3.0 technology.

USB (Universal Serial Bus) is a serial data interface for medium to slow peripheral devices. One of the versions of the interface is USB 3.0. In the specification, USB 3.0 connectors and cables of the updated standard are physically and functionally compatible with USB 2.0.

To clearly identify the USB 3.0 connection, it is common to offer it in blue plastic. The USB 2.0 cable contains four lines - a pair for receiving / transmitting data and a zero voltage supply.

It is important to mention that USB 3.0 is equipped with four additional communication lines, which leads to a thicker cable. The new contacts in the USB 3.0 ports are separate from the old ones in a different row of contacts. The USB 3.0 specification increases the maximum data transfer rate to 5 Gb per second compared to 480 Mb per second with USB 2.0. This increases the transfer speed from 60 MB / s (30 MB / s effective) to 600 MB / s and enables the transfer of 1 TB in 1-2 hours.
