I got my hands on Seagate's BlackArmor 440 NAS server and it seems different from most NAS servers I've reviewed.
The BlackArmor 440 is one of two products in the BlackArmor NAS server family that Seagate introduced last Tuesday. The other is the BlackArmor 420. The only difference between the two is the 420 ships with only two hard drives preinstalled, leaving two bays empty, while the 440 comes fully populated with four drives. Both devices are aimed at business and home office environments.
These are the first NAS servers that are truly from Seagate. The company does sell and support a few others, such as the Central Axis, but under a different brand.
The BlackArmor NAS server has a rugged and compact look for a four-bay NAS server and comes with an easy-to-use, tool-free design. It can take up to four SATA hard drives of up to 2TB of storage.
Unlike other NAS servers I've seen, the BlackArmor has four USB ports and two Gigabit Ethernet ports. The USB port can host other external USB hard drives that can be set to contain the backup of the NAS server's internal storage. According to Seagate, this allows for offsite backup rotation.
