USB says new spec could double data transfer speeds

IDG News Service - PCs and mobile devices connected to peripherals via USB ports will in the future be able to transfer data at twice the speed possible today.

A new specification that doubles the data transfer over USB to 10Gbps is in the works, said the USB Implementers Forum, a standards-setting organization that defines specifications for the data transfer technology. The announcement was made at the Intel Developer Forum being held in Beijing.

The speed improvement means users will be able to move gigabytes of data between PCs and peripherals such as portable hard drives in a matter of seconds. That is especially useful when transferring large high-resolution video files.

The new specification is an improvement over the existing USB 3.0, which can transfer data at 5Gbps. Most PCs today ship with USB 3.0 ports, while smartphones and tablets have micro-USB ports based on the older and slower 2.0 specification. Mobile devices will get faster signalling rates with micro-USB 3.0 ports in the future.

The speed increase comes on the heels of Intel’s announcement this week that it is doubling the speed of Thunderbolt, an interconnect based on PCI-Express and DisplayPort that is viewed as a faster alternative to USB. By the end of the year, Thunderbolt will boast data transfer rates of 20Gbps, but USB 3.0 has an advantage of wider adoption and backing of some top hardware makers including Hewlett-Packard, Dell, Microsoft and Intel. Intel views USB 3.0 and Thunderbolt as complementary technologies.

USB-IF did not say when the new specification would be approved and released.

Peripherals based on the new standard will be able to plug into existing USB 3.0 ports. However, new cables will be needed to handle the faster speeds.

The last major update to the USB 3.0 specification in July involved the connector cables being able to deliver up to 100 watts of power, which could charge mobile device batteries faster and enable televisions to be powered via a USB port.

:bigsmile:I just bought a Lexar USB 3.0 Jump drive, that is faster than my old Veloscirapor LOL. Lexar call it the " Triton" and I am getting 200mbs read and write, I didn’t think it could much faster.:bigsmile:

Is that sustained, or is caching involved?

Sustained, google it it the Lexar Tritron 3.0, I bought it on Amazon.

Specs say ~ 155MB/sec for read AND write… that’s the real deal… up until now most have write performance under 60MB/sec… the 3.0 drives usually are above 60, but below 100MB/sec. Over 100MB/sec is a vast improvement and you pay a premium accordingly… $65 for 32gb $115 for 64gb. vs ~$30-$45 for entry level 3.0 flash drives @ 64gb.

I do believe that YMMV depending on the usb 3.0 chipset your working with. Anecdotal reports from forums I’ve read vary on what benchmarks say. So it’s possible to get 200MB… but probably on small files ~300mb ~2gb each instead of say 12gb single files.
