Features HDD capacity The maximum storage capacity of the hard disk, usually measured in bytes e.g. GB. 18 TB HDD speed The rotational speed of a hard disk expressed in rotations per minute. The faster the better. 7200 RPM Storage drive buffer size 512 MB HDD size The amount of data that the hard drive can store. 3.5" Interface Interface ports to connect pieces of equipment. USB (Universal Serial Bus) has become the most popular wired interface to connect peripherals. USB 2.0 supports speeds up to 480 Mbit/s (USB 1: 12 Mbit/s). The interface FireWire is also known as the IEEE 1394 standard. Enhanced IDE (EIDE)is sometimes referred to as Fast ATA, Fast IDE or ATA-2. Serial ATA III Type Characteristics of the device.
