We tested five Network Attached Storage (NAS) appliances, ranging from 4T to 18TB in capacity and targeted for small offices and businesses with up to 20 to 25 users. All are more-or-less in the same price range: about $700 to $2,000 with drives.
Our participants were: D-Link’s Share Center Pro, Western Digital Sentinal DX4000, Thecus N4800Eco, Ctera C200 and ioSafe N2.
All of the units provide basic NAS functionality. They support RAID drive configurations and offer iSCSI support. They all provide local accounts and directory authentication for controlling user access. They support the popular file sharing protocols: CIFS (Windows), NFS (Unix/Linux), AFP (Mac), FTP, and offer at least basic remote web access.
