What is NAS (Network Attached Storage)? NAS Explained in Minutes


Jamison Cush: Let’s call it a giant virtual file cabinet. Network attached storage, or NAS, is file storage that enables multiple users to store and retrieve data from a centralized disk capacity. And it makes working remotely and collaborating more convenient. In the enterprise, a NAS array can be a backup target for archiving and disaster recovery, and can also serve email, multimedia files, databases, or printing jobs. Because of its ease of access, high capacity, and fairly low cost, it’s an attractive option, but it has limitations. NAS performance can be severely impacted if users overwhelm the system and the disk competes for input and output resources. There are different types of NAS devices to choose from, based on the number of drives, drive support, drive capacity, and scalability. A high-end, enterprise-grade NAS stores vast quantities of file data and provides rapid access and NAS clustering capabilities. On the other hand, a low-end or desktop NAS is aimed at small businesses and home users that require local shared storage. This market is shifting toward a cloud NAS model, enabling storage access over the internet, as if the storage was local.
