Summary: I am a happy user and owner of a DNS-323 the 2-bay version of this device, and I would like to upgrade. It is robust, simple, low power, and works well, and keeps things cool. The problem is that I also own the 4-bay QNAP NAS device, which has all kinds of software, and services for almost the same price. DLink is over-priced. When this gets down to about the price I got the DNS-323 at I would say, consider it, but until then it is too costly.
