The NAS just arrived a little bit ago. I found the quick setup guide to be very easy to follow mostly because all the steps are so simple. If you need more detailed instructions, the full manual is available for download. I'd say it took me about 5 minutes to hook it up to the network, turn it on, download the software, install it on my PC, and have it up and running. It took me about 10 more minutes to read about setting up folders and set up what I wanted. It was so simple I probably could have skipped the instructions. Then it took me about 15 minutes to set up the DLNA server, which I am completely new to, and have it running on my Roku TV with the Roku Media Player.So far it seems to be working flawlessly, ofcourse we will have to see if that lasts.Pros:1) Extremely cheap when you consider it comes with two 2TB hard drives installed.2) Super easy setup3) Super easy and very simple web interface4) Have it working on multiple computers and my DLNA Roku very quickly5) EULA was super short and simple unlike some other NAS companies that I saw have EULAs requiring that you allow them the right to audit your use of the device, access your site, see your books, etc. Are you kidding me?6) Has a USB connection for an external drive which I think will come in handyCons1) Maybe lacking in utilities compared to some other companies. I just wanted very basic functionality so I'm actually happy without all the extras.2) Speeds copying data over the network to the drive so far have been about 17 MB/s for one computer and combined 24 MB/s when copying from two computers at once. I don't know how much of that is the device and how much is the other drives I'm copying from. But, it does seem a little on the slow side to me.
