Todd wants to know about the WD My Cloud Mirror. Is it network attached storage? Leo says it is, but it's supposed to be an appliance for those who aren't very technical. It comes with WD dual drives, will work with Mac or PC, but it doesn't have as many features as a traditional NAS. It will connect to cloud solutions like DropBox for off site backup. There's also a feature he likes that will allow him to connect to the computer directly and copy the files over. At $291 for 4TB of storage, it's a great deal.
