Specifications, Availability and Pricing
At the heart of the Synology DS411+II is a dual core 1.8 GHz processor that is paired with 1GB of DDR2. The system supports four HDDs in either 3.5 or 2.5" form factors. At the time of writing Synology says they support up to 3TB drives; we'll have to see if this gets updated later to the new 4TB models that are just around the corner.
On the connectivity side of things you have a single gigabit Ethernet port, dual USB 2.0 ports and a single eSATA port. That should be enough to keep you busy for a while.
The DS411+II is cooled by dual 80mm fans. Synology gives a dB rating of 22.5. With the system just four feet away from our primary seating position in an enclosed small office, we never knew when the system was off or on other than the lights on the front of the NAS. The system ran very quiet.
Synology gives a two year warranty with the DS411+II should you ever encounter an issue. Online you are able to find this system in several different configurations. Those range from a bare system without hard drives to a fully loaded system with 12TB of raw capacity. Our system arrived with four 1TB drives already installed.
A bare system void of drives will set you back around 640 Dollars. At that price we are clearly talking about a machine that is built for business, but we didn't realize how much business the DS411+II was capable of until we started looking at the software and feature list.
