Toll-equipped hard drive is preformatted for MacOS X. What stands out is particularly positive that the hard disk supplied together every imaginable cable, which is no longer taken for granted today. It was both a USB, as well as a FireWire 800 and a FireWire 400 to 800 cable in the package, which makes it possible to connect 400 the hard drive work on older Macs via FireWire and thus connect several hard disks in series to what still does not work at USB today, and only via a USB hub. You can therefore theoretically operate up to 64 hard drives on one FireWire port. The hard disk has a good quality and is afloat. They also watched by her design ideal for current Mac-style. The cabinet is constructed from high quality plastic and with sufficient ventilation slots. The plate is not hot during operation and does not interfere with a penetrating fan noise. In addition, the hard drive will automatically switch on and off, even when one puts the Mac into hibernation. A highly recommended, external hard drive.
