    everything i wanted
    5 Stars
    everything i wanted
    I'm really glad I found this unit at such a great price point. I dropped in a couple of 2Tb drives and I no longer have worries about losing any of my data. My purpose for this device was to have mirrored drives, on my network, quick to connect to while being quiet and unobtrusive. All of these needs are met. Whenever I connect to the unit to access my file system, there is no delay or that infernal hourglass. It's like the files are right here on my computer. It is easy to manage through a web interface and there are a lot of add-on software options that can be added to really step up the game. Five stars? YES!
