The Mirror automatically powers up when you plug it in, and, as the assumption is that you’ll be leaving the box on 24/7 (it needs to be on for you to access the files) there’s no power button. That makes it less accident prone, and you can still turn the unit off using the admin menu in the web configuration interface. You can also schedule its active/sleep hours using the settings page.
The My Cloud Mirror itself carries a 2-year warranty, and the WD Red NAS drives inside are good for a year beyond that.
A great deal, if you don’t need more.
At retail from WD’s online store, the 4TB My Cloud Mirror costs $310, the 6TB version is $370, and the 8TB is $410. That’s not significantly cheaper than than a similarly populated QNAP HS-210 or a Synology DS-214se with their broader capabilities. However, I found the My Cloud Mirror online for $260, $320, and $360 respectively. That’s a bargain.
