SEAGATE'S 3TB (three terabyte) external drive is currently the highestcapacity hard disk available to consumers.
The FreeAgent GoFlex Desk external drive stands out from the rest because of two features.
Its standard USB 2.0 interface can be upgraded to USB 3.0 or FireWire 800 (for much faster transfer speeds) via an adapter.
Also, an NTFS driver for Macs is included, which makes the hard drive usable on both PC and Macs.
Previously, drives had to be formatted in FAT32 before they can be used by PC and Macs.
FAT32-formatted drives have an inherent 4GB limit on individual file sizes, making them unsuitable for storing much larger DVD and Blu-ray movie files.
