Best NAS appliances for small business


When we tested Network Attached Storage devices seven years ago, the products boasted an amazing (for the time) 1TB of disk space. This time around, we’re testing six units that sport 8TB or larger storage capacities – for just about the same price as the first batch back in 2005. This time around, however, the appliances include antivirus, print server, cloud backup, file indexing and searching, plus RAID-5 or RAID-6 to protect data if a drive fails.
