Difference Between USB and FireWire
Summary: Difference Between USB and FireWire is that a USB flash drive, sometimes called a thumb drive, is a flash memory storage device that plugs in a USB port on a computer or mobile device. You can use a FireWire hub to attach multiple devices to a single FireWire port.
A USB flash drive, sometimes called a thumb drive, is a flash memory storage device that plugs in a USB port on a computer or mobile device. USB flash drives are convenient for mobile users because they are small and lightweight enough to be transported on a keychain or in a pocket. Current USB flash drives have storage capacities ranging from 512 MB to 64 GB, with the latter being extremely expensive.
You can use a FireWire hub to attach multiple devices to a single FireWire port. A FireWire hub is a device that plugs in a FireWire port on the system unit and contains multiple FireWire ports in which you plug cables from FireWire devices.
Previously called an IEEE 1394 port, a FireWire port is similar to a USB port in that it can connect multiple types of devices that require faster data transmission speeds, such as digital video cameras, digital VCRs, color printers, scanners, digital cameras, and DVD drives, to a single connector. A FireWire port allows you to connect up to 63 devices together. The three latest versions, FireWire 800, FireWire 1600, and FireWire 3200, have speeds faster than the original FireWire 400.
