14.Jul.2010 FireWire vs. USB debate

Both FireWire and USB technology is admittedly similar, helping users to transfer data from device to device with as little difficulty as possible. While they are similar, that is not to say the two are interchangeable, each operating under separate setups leading to a degree of differences that may cater better to individual needs.FireWire uses a “peer-to-peer” communication system in which each periphery apparatus is treated as an equal in communication. This allows for each connected device to communicate with any other individual device without having to use the computer as a central translator or hub. This allows for the peripheral devices to negotiate bus conflicts and determine which device is best suited for the data transfer.USB, on the other hand, uses a “master-slave” communication system in which all periphery devices are subject to the will of the central controlling computer. In this model, the base computer arbitrarily makes decisions on data flow and compatibility.The difference in operation places additional system overhead on the USB model which results in slower data flow control and download speeds. While FireWire provides higher speed data transfer, this does not render USB obsolete. USB technology is very practical in providing compatibility between multiple computers in the form of USB external hard drives. Commonly known as flash drives or just USB drives, these small transportable files vary in storage capacity. Often fitting conveniently on a keychain, a flash drive can simply be inserted into a USB port, files are then dragged or uploaded to the device, then the drive is removed and the data is available for upload on any other computer with a USB port.A rule of thumb when deciding between using FireWire and USB is the amount of data you intend to transfer. Firewire is intended for higher data-usage, commonly coordinating devices such as digital audio equipment and DVD players, while USB offers a simple transferring solutions for simpler devices.
