Specifications, Availability and Pricing

The Seagate BlackArmor 400 Series consists of four models at this time. The flagship 440 ships with four drives installed and has a capacity range of between 4 and 12TB. The 420 that we are reviewing today ships with two of its four drive bays loaded and is currently offered in 2 and 4TBs. The budget 400 model ships diskless; you will need to purchase and install your own set of hard drives.

Other than the drive count, the Seagate BlackArmor 400 Series of products are identical. All three use the same NAS enclosure and the same features. There are 10 licenses for the backup software for Windows, all the RAID features you could ask for are included and the systems support Hot Swap technology.

The part we really like about the BlackArmor is the price. While looking at Newegg, we found the 400 diskless system available for 389.99. The 420 4TB model that we are reviewing today for 749.99 and a 440 model with 8TB unit for 1299.99. These prices are quite a bit lower than most of the other 4-drive NAS servers we've tested.
