Pros: Small, quiet device that it is very easy to setup. Was up and running in a matter of minutes. Great documentation too, with an easy step-by-step setup guide. The dual core ATOM CoC CPU performs like a champ, with very good file transfer speeds, both on downloading and uploading. The unit is also very well built and the design is elegant.
Cons: Web UI somewhat basic and rough on the edges. The Transmission (Bittorrent client) web UI is basic to the extreme. For example, it does not me to pick individual files within a torrent for download. But overall, I feel that those are minor grips.
Cons: Difficult to set up, this NAS is for geeks or very tech people. Thecus support is the worst. This device does not play 1080p videos, other type of videos just lag or hear the audio only. Contact Thecus support they say is beacuse the device lack of resources, the recommend to go to the Higher level which cost more than twice as much.
Summary: Unit is just very simple. Seamless. All the qualities a home NAS should have.
Pros: NO HDD TRAYS REQUIRED! Super easy set-up. Quiet, even quieter than most gaming consoles. HDMI - Didn't even really need to access software apart from set-up. Just plug and go. Aesthetically appealling.
Summary: I wasn't able to play my HD videos at first. So I contacted Thecus Tech support and they were very helpful. They told me to configure my DNS and install XBMC. Worked like a charm after that.
Pros: I was surprised how fast and easy it was to get this thing up and running. I installed my 2 " 2 TB WD Red hard drives", and had raid 1 configured with simple steps in minutes. After mapping the drives I transferred around 380 GB <200 minutes. One of the great things I like about this NAS, is that I can play HD videos after connecting my HDMI monitor to the NAS.
