SS USB cables transfer data at a max rate of 5 Gbps (5,120 Mbps), though 3,200 Mbps is a more realistic and common rate for average use. Conversely, USB 2.0 transfers at 480 Mbps, and USB 1.1 has a maximum transfer of 12 Mbps.

The SuperSpeed (SS) USB 3.0 Cable is designed to connect a device with a USB Type A interface to one with a USB 3.0 Type B interface. It is ideal for connecting an audio interface, external hard drive, or other computer peripherals to a PC via a SS USB Port.
Nearly all modern electrical devices utilize a standard that is compatible with USB 3.0 cables. Some devices utilize USB 3.0 connectors Type B and Micro B, such as printers, scanners, storage drives, GPS units, and cell phones.

USB Type A connectors have been the universal standard since USB 1.1, with connections built into wall sockets, computers, vehicles, televisions, interfaces, and audio technology of all kinds. USB 3.0 Type B can be found on larger devices such as printers and scanners. Some storage devices and drives use them, as well.

Features include: • SS data transfer rates up to 5 Gbps (system dependent) • Compliance with the USB 3.0 interface standard • Nickel-plated plugs for enhanced signal transfer
USB 3.0 cables utilize 9 connector wires, as opposed to 4 connector wires in USB 2.0. This allows for higher transfer speeds and more voltage. For charging devices, USB 2.0 is capable of up to 500 mA, whereas USB 3.0 is capable of up to 900 mA. The 5 additional wires also enable USB 3.0 cables to have two-way communication simultaneously. Unique connector types for USB 3.0, which are most often blue in color, are Type B and Micro B.
USB (Universal Serial Bus) 3.0 was released in 2008 with approximately 10x the speed of USB 2.0 and was coined “SuperSpeed”. Because USB 3.0 utilized some of the same connector types as USB 2.0, along with a few new connectors, it was suggested that USB 3.0 cables be made blue to differentiate them. You can also see a compatibility chart of connector types here.
SIGMA has always leveraged the most advanced optical technologies to offer photographers the highest level of lens performance. Now, SIGMA is proud to offer the first lens in an all-new product line: the 35mm F1.4 DG HSM. This wide-angle F1.4 lens delivers the highest level of brightness and beautiful bokeh effects. It offers the unique characteristics that only a large-aperture F1.4 lens can offer: shallow depth of field along with superior low-light and hand-held performance.
