Summary: Certainly not high performance. The device is slow, and has insufficient resources to efficiently run a Windows Storage Server 2012 implementation. The installation of Windows sucks up a partition on the first two disks, limiting the size of a 4-disk array (you essentially lose 400GB of raw storage going RAID 5). The "RAID Builder" included software just scripts Windows software based RAID, there is no actual controller.
Great for a home network storage device, but not super reliable

Summary: I've had quite a few TeraStations over the years, including a couple of this 16TB model. We back up all of our photos and videos, but always keep at least one other copy somewhere. Even though these will preserve data if one drive fails, you can't really count on that. If you put this in a closet and don't pay attention to it (as I have done,) you might find that *two* drives die before you know there's a problem.
Summary: This terra station was the best deal I could find with existing drives. I had my IT vendor set it up as a local backup NAS for my server. It has a web interface that I haven't taken the time to figure out. It was nice not having to spend the extra time and money purchasing separate drives and the price is competitive. My only real gripe is that the fans are extremely loud.
Summary: I have to say that at this time I have nothing negative to say about the Buffalo TeraStation 5400. It is a solid piece of equipment. It is very intuitive and I was able to set it up quickly. I setup drive mappings to everyone's personal folder and I no longer worry that I'm going to lose data on any device. I do have to work on a backup solution for the drive though. I also like that I can remotely access the unit without messing around with any router settings.
Summary: I was extremely pleased with the product but most of all with the support I received from Kerry at Buffalo Tech Support. He was extremely patient and made sure he answered all of my questions. I received a response within thirty minutes (if not immediately) if I contacted tech support.
