These high capacity 3.5" hard drives utilise the high speed SATA III 6Gb/s interface. Ideal when high transfer rates are essential. The speed of the SATA III interface makes these range of drives the preferred choice for the most demanding of systems and advanced applications such as a RAID setup. Some hard drives include NCQ (Native Command Queuing), which allows the drive to internally optimise the order in which received read and write commands are executed. The SATA III interface is backward compatible.
