Hardware Specifications and Pricing
Modern NAS servers have moved beyond data storage through a wire network. In order to get the most out of a NAS you need to look at the extra I/O hardware, and the mountain of potential software features.
The base hardware is the same for the four models offered by Seagate. Seagate used an Intel Atom dual-core processor with hyper threading, and running at 2.13GHz. The systems ship with 4GB of DDR3, and have two gigabit Ethernet ports for failover, dual networks, or 802.3ad. Three USB ports (two 3.0 and a single 2.0) aid in getting data to the drives, as does the USM port that accepts a USM enclosed HDD right on the front of the NAS.
The divide between the four models comes from the drive configuration and capacity. The entry-level model uses two 2TB drives, and is marketing as 4TB. Moving through the product SKUs, we have the 4x 2TB for 8TB of marketed capacity, the 4x 3TB for 12TB, and finally the model we're testing today, with 4x 4TB drives and marketing as a 16TB unit.
The Seagate Business Storage Windows Server 4-Bay NAS has a three-year warranty, and ships with an external power supply, Ethernet cable, USB key with system recovery software (in this case Windows Storage Server 2012), and a quick start guide.
