USB Naming
After I found this fantastic table on the website of club 3d, I replaced my old table with this one.
| Spec | Name | Previous name | USB-IF branding | Data rate | Transfer speed | LOGO |
|---|---|---|---|---|---|---|
| USB 3.0 | USB 3.2 Gen 1 | USB 3.1 Gen1 | SuperSpeed USB 5Gbps | 5 Gbit/s | 500 MB/s |  |
| USB 3.1 | USB 3.2 Gen 2 | USB 3.1 Gen2 | SuperSpeed USB 10Gbps | 10 Gbit/s | 1.21 GB/s |  |
| USB 3.2 | USB 3.2 Gen 2x2 | N/A | SuperSpeed USB 20Gbps | 20 Gbit/s | 2.42 GB/s |  |
| USB4 | USB Gen 2x2 | Thunderbolt 3 | SuperSpeed USB 40Gbps | 40 Gbit/s | 4.8 GB/s |  |
USB 3.2 Gen 2x2 is just 3.2 Gen 2 with two lanes each 10 Gb/s (2x2).
