USB drives with USB 2.0 support can store more data and transfer faster than much larger optical disc drives like CD-RW or DVD-RW drives and can be read by many other systems such as the Xbox One, PlayStation 4, DVD players, automobile entertainment systems, and in a number of handheld devices such as smartphones and tablet computers, though ...
The written USB 3.0 specification was released by Intel and its partners in August 2008. The first USB 3.0 controller chips were sampled by NEC in May 2009, [4] and the first products using the USB 3.0 specification arrived in January 2010. [5] USB 3.0 connectors are generally backward compatible, but include new wiring and full-duplex operation.
The USB interface is hot-swappable (devices can be exchanged without shutting the host computer down). Small devices can be powered directly from the USB interface, eliminating the need for additional power supply cables. Because the use of the USB logo is only permitted after compliance testing, the user can have confidence that a USB device ...
On the device side, a modified Micro-B plug (Micro-B SuperSpeed) is used to cater for the five additional pins required to achieve the USB 3.0 features (USB-C plug can also be used). The USB 3.0 Micro-B plug effectively consists of a standard USB 2.0 Micro-B cable plug, with an additional 5 pins plug "stacked" to the side of it.
The absence of moving parts in USB flash devices allows true random access, thereby avoiding the rotational latency and seek time (see also mechanical latency) of hard drives or optical media, meaning small programs will start faster from a USB flash drive than from a local hard disk or live CD. However, as USB devices typically achieve lower ...
HD DVD drives can also be used with a desktop/laptop (notebook computer) or personal computer (PC (like a desktop or portable/luggable)) running Windows XP, Windows Vista, Mac OS X v10.5 "Leopard", and many varieties of Linux. Third-party player software for Windows and Linux have successfully played HD DVD titles using the add-on drive. [83]
USB-C plug USB-C (SuperSpeed USB 5Gbps) receptacle on an MSI laptop. USB-C, or USB Type-C, is a 24-pin, reversible connector (not a protocol) that supersedes previous USB connectors and can carry audio, video, and other data, to connect to monitors, external drives, hubs/docking stations, mobile phones, and many more peripheral devices.
Some devices, such as 2.5-inch drives, can operate off the 5 V supplied by laptop eSATAp ports. Others, such as 3.5-inch drives, also require 12 V; they can be powered from a desktop eSATAp port, but require an external 12 V power supply if used with a laptop computer. This can lead to confusion if users are not aware of the distinction.
