NAS devices are connected to the LAN as an independent network device and assigned an IP address. The primary advantage of NAS devices is that network storage is no longer limited to the storage capacity of a computing device or the number of disks in a local server. Many NAS products can hold enough disks to support RAID, and multiple NAS appliances can be attached to the network for storage expansion. There are many different types of NAS devices, ranges from beginners to experts. The features and specs will vary on the unit and manufacture.
