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 25 users. All are more or less in the same price range: about $700 to $2,000 with drives.
Our participants were the D-Link Share Center Pro, Western Digital Sentinal DX4000, Thecus N4800Eco, Ctera C200, and ioSafe N2.
All 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), a d FTP. All offer at least basic remote Web access.
The best NAS for your business depends on the capacity you need and what you want to do with it. For example, if data safety is the No.1 priority you'd want to opt for the disaster-proof ioSafe N2 unit, which also offers many more server and network functions over the traditional NAS feature set.
