December 06, 2010, 5:13 PM — Buffalo Technology shattered the $1,000 barrier for a terabyte of shared storage back in 2005. With storage prices continuing to drop, that same $1,000 today can buy a 4T or even 5TB network-attached storage (NAS) device with RAID 5 disk redundancy, plus additional features, like backup storage licenses and indexing capabilities.
We tested eight units, each suitable for workgroups in large enterprises or as an entry-level server for small businesses. Our test group included Buffalo TeraStation III, Iomega StorCenter, Netgear ReadyNAS, Western Digital ShareSpace, Seagate BlackArmor, LaCie 5big Network 2, Verbatim PowerBay, and the QNAP TS-459 Pro II. We tried to get a unit from Cisco, but its NSS 300 Series Smart Storage units are undergoing a major refresh, and won't be available until 2011.
