Within the past 23 years, USB 3.0, the third major version of the Universal Serial Bus (USB) standard has become the standard interface for interfacing computers and electronic devices. Every daily used digital devices like camera, mouse, printer or smartphone and notebook are with the physical connection to transfer data between devices. Thanks to the USB Standard, this port is indeed universal.
What is USB 3.0
USB 3.0 is the third major version of the Universal Serial Bus (USB) standard for interfacing computers and electronic devices. Among other improvements, USB 3.0 adds the new transfer rate referred to as SuperSpeed USB (SS) that can transfer data at up to 5 Gbit/s (625 MB/s), which is about ten times as fast as the USB 2.0 standard. Manufacturers often distinguish USB 3.0 connectors from their USB 2.0 counterparts by blue color-coding of the receptacles and plugs.
USB 1.0 VS. USB 2.0 VS. USB 3.0
USB technology has been under development since 1993.
USB 1.0, was introduced in 1996 which provides a Low-Speed transfer rate of 1.5 Mbits/s for sub-channel keyboards and mice, and a Full-Speed channel at 12 Mbits/s.
USB 2.0, which came in 2001, made a leap to Hi-Speed transfer rates of up to 480 Mbits/s.
In 2010, USB 3.0 has finally came out that can transfer data at up to 5 Gbit/s (625 MB/s), which is about ten times as fast as the USB 2.0 standard.
USB 3.0 devices:
Manufacturers of USB 3.0 host controllers include, but are not limited to, Renesas Electronics, Fresco Logic, ASMedia Technology, Etron, VIA Technologies, Texas Instruments, NEC and Nvidia. As of November 2010, Renesas and Fresco Logic have passed USB-IF certification. Motherboards for Intel‘s Sandy Bridgeprocessors have been seen with Asmedia and Etron host controllers as well. On 28 October 2010, Hewlett-Packard released the HP Envy 17 3D featuring a Renesas USB 3.0 host controller several months before some of their competitors. AMD worked with Renesas to add its USB 3.0 implementation into its chipsets for its 2011 platforms.[dated info] At CES2011, Toshibaunveiled a laptop called “Toshiba Qosmio X500″ that included USB 3.0 and Bluetooth 3.0, and Sony released a new series of Sony VAIO laptops that will include USB 3.0. As of April 2011, the Inspiron and Dell XPS series are available with USB 3.0 ports, and, as of May 2012, the Dell Latitude laptop series, yet the USB root hosts fail to work at SuperSpeed under Windows 8. On 11 June 2012, Apple announced new MacBook Airs and MacBook Pro with USB 3.0.
So as the development of the USB 3.0 high speed data transmission, there is now also USB 3.0 HUB for USB 3.0 user that ensures the high speed of the USB 3.0.
In general, a hub is the central part of a wheel where the spokes come together. The term is familiar to frequent fliers who travel through airport “hubs” to make connecting flights from one point to another. In data communications, a hub is a place of convergence where data arrives from one or more directions and is forwarded out in one or more other directions. A hub usually includes a switch of some kind. (And a product that is called a “switch” could usually be considered a hub as well.) The distinction seems to be that the hub is the place where data comes together and the switch is what determines how and where data is forwarded from the place where data comes together. Regarded in its switching aspects, a hub can also include a router.
Two Types USB 3.0 Hub
- A USB hub is a device that allows multiple peripherals to connect through a single USB port. It is designed to increase the number of USB devices you can connect to a computer. For example, if your computer has two USB ports, but you want to connect five USB devices, you can connect a 4-port USB hub to one of the ports. The hub will create four ports out of one, giving you five total ports. The USB interface allows you to daisy chain USB hubs together and connects up to 127 devices to a single computer.
- Some USB hubs include a power supply, while others do not. If you’re connecting basic devices like a mouse, keyboard, and USB flash drive, an unpowered or “passive” USB hub should work fine. However, some peripherals, like external hard drives and backlit keyboards, require additional electrical power. In order for these types of devices to function through a USB hub, you may need use a powered or “active” hub that provides 5 volts of power to connected devices.
How to pick the best USB 3.0 Hub
A great USB hub must have USB 3.0 ports and dedicated power. It needs to be reliable, well-designed, light, and compact. A decent warranty and LED indicators for each port are also useful.
This thing is Mac aesthetic all the way, its polished aluminum is not only durable but matches the design of the Apple Wireless Keyboard and Trackpad. Its ports are at an angle, which makes them easy to reach. The power plug goes in one end and the USB-computer connection is on the other end. It’s a clean design which looks great on the desktop as well as being very functional.
The HooToo HT-UH010 USB hub has seven USB 3.0 data ports and two charge ports for tablets and smartphones. Its vertically-stacked, upward-facing ports keep devices from taking up too much room on your desk, and the hub isn’t ugly, either
A USB 3.0 cable is required for USB 3.0 speeds, but any USB cord will make a connection.
SuperSpeed (USB 3.0) is supported only by USB 3.0 and newer interfaces, and requires a connector and cable with extra pins and wires, usually distinguishable by the blue inserts in connectors.
USB 3.0 cables can be used with 2.0 devices and ports if the connector types fit (no B Male or B Micro connectors), but the transfer rate will fall back to 2.0.
Even we have now USB Type-C, which also be called sometime USB 3.1. But we have one case to show you that the USB Type-C will be not widely used in a short time. USB 3.1 devices are not so much as we predicted this year, and also the Samsung Galaxy S7 is not equipped with USB Type-C or Quick Charge 3.0, which shows the main manufacturers still need time to test new ports for their new devices.
