The thing of this review is, you guys didn't scratch what is out there for NAS arrays, especially Synology's The model you chose here was one of their basic models. Sure, Intel's bargain basement processors, Gbit networking, what did you expect? If you got a firecracker like the DS420+, my friend, you would look back at your previous choice and say "what a fool I was to have chosen that cracker box".
I own 5 different Synology NAS arrays and have yet to regret any of my decisions to purchase them. My latest (and greatest) is a (surprise!) DS420+. Stuffed with 16TB (10TB working with SHR RAID) of Seagate's finest and 6GB under the hood, it sings for me each time I push or pull files to it. My eldest still chugs away, babysitting a UPS battery, ready to send shutdown signals to my server garden if we go to candle power.
