it's easier to setup plug and play. no installation program. Connect to USB cable and it detects the usb hard disk straight away. It's a great unit to store information with USB 3.0, it's quite fast to transfer files and folder to the hard disk. It's advertised as 8TB, however you would get 7+TB because of the NTFS formatting. It comes with 2 years warranty but my disk still running good after a year. In comparison of the current price with other vendor, the wd hard disk price is pretty decent and slightly inexpensive. The only thing which i don't really like is it's only running on 5400rpm instead of 7200rpm. If you use this to stream videos, you're going to run into trouble. But if you're using it for backup, it's a perfect hard disk.
