USB 2.0: The Standard
USB, or universal serial bus, is a type of serial interface that allows one to transfer data by attaching external devices to a computer. Most USB products, such as digital cameras, mice, or external hard drives are “plug-and-play,” meaning you don’t have to install anything to use the product. Instead, one just plugs the external device into the USB port and the computer will automatically detect it. In these ways, USB technology greatly simplifies the installation of hardware on a computer, allowing devices to be attached/detached while the computer is in operation.
USB 2.0 is currently the standard and universal USB interface to transfer data between computer to device. It surpassed its 1.1 predecessor, but is currently being challenged by the USB 3.0 technology.
USB 3.0: The Next Generation
USB 3.0 is expected to take data transfer speeds to the next level. USB 3.0’s transfer rate is rougly 4.8 gigabits per second. Wisegeek estimates for 25 gigabytes to be transferred, USB 2.0 would take 14 minutes while USB 3.0 would take about 70 seconds.
USB 3.0 costs more than the 2.0 version, so only buy the former if your aim is to transfer data quicker and smoother. If you will use the 3.0 to connect an external device that does not have the specific task of transferring lots of data (e.g. printer, keyboard, mouse), the 3.0’s speed won’t be noticeable. But for hard drives, cameras, or other storage devices, USB 3.0 is the right choice for you.
As a final note, the plug connector for USB 2.0 and 3.0 look exactly the same. However, USB 3.0 will only work with 3.0 compatible connectors. 2.0 also works with 3.0 compatible connectors, while 3.0 does not work with 2.0 compatible connectors.
Popular USB Products from Bytecc
Bytecc is a company that specializes in USB interface products. Eio highlights some of their more popular products!
The USB3-ESATA is an adapter cable for USB 3.0 to eSATA connectors. It has a two-inch length in between plugs which give slightly more reach. The transfer speed also triples in speed, making the transfer rate three times as fast than when using USB 2.0.
The BT-144 is an external device that allows one to transfer the data off of 3.5″ floppy discs onto the computer. Many computers no longer have floppy disc drives, which make the BT-144 highly useful. It has an ultra slim design and does not require any external power to function. It is plug & play, and easy to carry around. It is Mac OS 8.6/9.0/9.0.2/9.0.4/9.1 and Windows 95/98/2000/ME/XP compatible.
The BT-300 is a USB 2.0 to IDE/SATA adapter. It can connect to any device with an IDE/SATA interface to a PC with USB interface. The data transfer rate is approximately 490 MB/ps and comes with an external power adapter for IDE/ATAPI/SATA devices. It is also Linux and Mac compatible.
