The Western Digital Elements Desktop is a reliable hard drive with no less than 6 TB of storage. Its USB 3.0 connection provides lightning-fast data transfer if you use the Elements Desktop in a USB 3.0 port on your computer. Of course, it also works on a USB 2.0 connection, without the speed that USB 3.0 has to offer you. The Western Digital Elements Desktop can already be used on a Windows PC out of the box. Mac users should reformat it.
The cheapest i can find, also says so on tweakers.
