Pros: I bought this to replace a dying HP Home Server that was primarily just being used as a NAS anyway. I have this for central storage for home and work, mapped as multiple drive segments, accessed by a Windows Desktop, a MacBook Pro (using Time Machine), an iPad, and two Android phones. It also serves as my central iTunes Library storage. It's been *very* reliable. The administration pages includes way more features than I have the current knowledge to use, but it was quite straight forward on the basics and provided enough to make it pretty clear about each part so I could interpret if I used it or if I could safely turn something off. (I'm not a hardware/networking beginner, but mostly been involved in basic PC troubleshooting, not setting things up network devices from the beginning. In this area, I can interpret information given the context enough to serve me and otherwise, I know just enough to be dangerous, so I usually avoid such a task without assistance. I got through this device setup on my own, short of one question about a service I couldn't determine as necessary or redundant.)

Cons: I've had no issues with the system over this first year. (Knocks on wood).

Overall Review: I would definitely buy a Buffalo product again and would recommend this to someone looking for a Home/Home Office NAS system. I do not use any streaming connectivity or try to use it for publicly hosting any files for others to access. I cannot give feedback on its performance in those roles.
