(also network-attached storage)

NAS definition

NAS (network-attached storage) is networked storage that allows multiple users and client devices to access data from a centralized disk capacity. NAS devices connect to a wireless router and provide file access to computer systems. Using NAS systems, remote workers can access files from any mobile or desktop device with a network connection.

How does NAS work?

  • NAS systems use a NAS device – a specialized computer designed to support storage through network access.
  • The device has four major components: CPU (central processing unit), network interface, physical storage (e.g., disk drives), and operating system (e.g., Netgear ReadyNAS).

How can NAS be used?

  • Distributed team collaboration. Employees who work remotely might benefit from NAS because it allows users to share data and collaborate more effectively.
  • Storing and serving multimedia files. People may use NAS systems at home to manage smart TV storage, security systems, or consumer-based Internet of Things components. They may also use NAS to create media streaming services, host personal cloud servers or build and test a website.
  • Hosting server-based applications. Organizations may use NAS systems for hosting open-source applications like CRM systems, human resource management, or resource planning applications. Enterprises may also use NAS systems to support email systems, accounting databases, video recording, payroll, data logging, and business analytics.

Benefits of NAS

  • Ease of access. NAS allows users to access data remotely 24/7, which is excellent for remote team collaboration.
  • Easy to operate. NAS systems often come with simple scripts or pre-installed appliances. Therefore, companies may not need a dedicated IT person to set up and manage simple NAS systems.
  • Low cost. NAS is relatively affordable and may cost less than other network storage solutions.

Cons of NAS

  • Slow performance. With increased traffic, the performance of NAS systems may decrease.
  • Limited scalability. Compared to other storage systems, NAS is not as scalable.
