USB 3.1 doubles performance

USB 3.1 doubles the speed to 10 Gbps delivering up to twice the data through-put performance of existing SuperSpeed USB and is fully backward compatible USB connectors and cables. The USB 3.1 specification can be found at

Key characteristics of the higher-rate SuperSpeed USB solution include:
• New 10 Gbps USB data rate
• Compatibility with existing cables and connectors
• Improved data encoding for more efficient data transfer leading to higher throughput and improved I/O power efficiency
• Compatible with existing USB 3.0 software stacks and device class protocols
• Compatible with both existing 5 Gbps and new 10 Gbps USB 3.0 hubs and devices, as well as USB 2.0 products

Beside the speed increase the USB 3.1 specification also covers:
• USB Power Delivery
• USB Inter-Chip Supplement SSIC
• USB OTG 3.0

For testing the biggest challenge will be on the electrical level.
But also not forget the cable and connectors, there are many BAD cable and connectors that will cause headache knowing they not even work at 5Gb.....
