Understanding the External Hard Drive Specifications
IEEE 1394 (also known as Firewire) and USB 2.0 interfaces are widely used on the external hard drives. Both interfaces can provide relatively fast transfer speeds, hot-swappability, and cross-platform compatibility on both the PC and MAC. An external hard drive can contain one or more internal hard drives, whose capacity, rotational speed and cache size often determine the overall capacity and performance of the external hard drive.
