The special feature is that owning stainless steel case for no problems cause when it is plugged in and out ten thousand times.Some points: DVD at 8X writes at 1.32MiB/s * 8 = 10.56MiB/s, not 36MiB/s (36MiB/s is for BluRay at 8X).īut if Read medium is also on USB 2.0 (read from an enclosure and write to an external USB DVD writer) it can saturate USB 2.0 bus speed very easy.
It is the next-generation of Mini USB, supporting OTG and with the same pin quantity - 5 pins.
The Micro USB is the portable version of normal USB 2.0, the interface is smaller than Mini USB of some smartphone. It is widely used on SD card, MP3, digital camera and removable hard disk. The Mini USB B type is the most common interface because of the outstanding anti-wrong plug and compact size. It is divided into A type, B type and AB type. The Mini USB is another USB standard, which is smaller than the normal USB, more compatible with small electronics like mobile devices, etc. Also, the standard of USB 3.1 is compatible with USB 3.0 and 2.0 version. The USB 3.1 specifications replace the USB 3.0's SuperSpeed transfer a double rate - 10Git/s and reduces line coding overhead to only 3% by changing the encoding scheme to 128b/132b, the transfer speed arrives at 7.2Git/s. On 31 July 2013, the USB 3.1 was released by the USB group. But it is reasonable to get only around 3.2Gbit/s (0.4GB/s or 400MB/s) due to the overhead incurred by 8b/10b encoding and the 4Gbit/s payload throughput.
The USB 3.0 provides a data signaling rate of 5.0Gbit/s. It defines a new SuperSpeed transfer mode, which relates to new backwards-compatible plugs, receptacles, and cables. The USB 3.0 was released on November 12, 2008. However, only 280Mbit/s or 35MB/s can be produced due to the bus access constraints. The USB 2.0 was launched in April 2000, In addition to the 12Mbits/s - the fastest speed of USB.1., it is increased to 480Mbit/s high speed or high bandwidth. It has the speed of 12Mbit/s (fast speed). The USB 1.1 was released in August 1998, the earliest revision that was widely adopted and led to Pcs.
It does not allow for extension cables or pass-through monitors because of timing and power limitations. The USB 1.0 was released in January 1996, having specified a data rate of 1.5Mbit/s (Low Bandwidth or Low Speed). USB has effectively replaced a variety of earlier interfaces, such as parallel ports, as well as separate power chargers for portable devices. It has become commonplace on other devices, such as smartphones, PDAs and video game consoles. USB is designed to standardize the connection of computer peripherals (including keyboards, pointing devices, digital cameras, printers, portable media players, disk drives and network adapters) to personal computers, both to communicate and to supply electric power. It is currently developed by the USB Implementers Forum (USB-IF).
USB (Universal Serial Bus) is an industry standard initially developed in the mid-1990s that define the cables, connectors and communications protocols used in a bus for connection, communication, and power supply between computers and electronic devices.
