I purchased the DS920+ pre-configured in a RAID 10 array. This was a little more than what I was looking for, but as Synology was running a special I picked it up for a good deal. I’m glad I did... Synology kept me informed every step of the way from purchase to NASBit testing to shipping. When I recieved the product, I was able to plug it in, turn it on and start using it ,just like that. The user manual explains things well and if you’re the kind of person who has a general idea of what to do but needs a little clarification in specific areas, the Synology support team is very responsive. Overall, a great experience! I’ve had it now for about 3 weeks and I’m quite impressed with the capabilities of this product. Most notably, I love the transcoding feature because I have media stored in many different formats, not all of which I could play with my old device… now I can. There are many other features that I have yet to explore and can hardly wait!
