What Is a NAS and What Is it Used For?

The Network Attached Storage (NAS) Is Your Digital Hub for Storage and Beyond

A Network Attached Storage (NAS) device is a dedicated file storage system that connects to a network, giving you and other devices on the network access and storage to share and transfer data from a centralized location. NAS systems have evolved from simple file servers to powerful, multi functional devices that can serve as the backbone of home and business networks.

Common Uses of NAS

1. Centralized File Storage

The main reason of having a NAS is to have a central repository for your files. You can generally store pretty much anything and access stuff like documents, photos, videos and other data from any device on the network.

2. Backup Solution

NAS devices are great as a backup destination for computers and phones, so that your data is safer and easier to recover if your computer, phone or other devices fail or get lost.

3. Media Streaming

You can setup your NAS as a media server, music streamer, movies and TV show hub for certain other devices like smart TVs, PlayStation or Xbox consoles and phones.

4. Private Cloud Storage

You can also use a NAS as a personal cloud device turning it into your own personal Dropbox or Google Drive but with complete control over your data.

5. Collaboration Platform

In business environments, NAS devices help with file sharing and collaboration with your team members by integrating with productivity suites like Office 365 or Google Workspace.

Lesser Known Applications of the NAS

1. Virtual Machine Host

More powerful NAS systems can host virtual machines, which gives you the power to run multiple operating systems or applications directly on the NAS.

2. Docker Container Platform

Many modern NAS devices support Docker, which helps you easily deploy and manage containerized applications.

3. Surveillance System Hub

A NAS can be used as a central recording and management system for IP cameras. This is great for a home or business surveillance solution.

4. Web Hosting

Some NAS systems can host websites, which is helpful for small businesses or personal sites with moderate traffic. If you don’t want to always pay a recurring fee to a web hosting platform you might benefit from this idea.

5. Email Server

With the right software, a NAS will function perfectly fine as an email server, giving you complete control over your email infrastructure.

6. VPN Server

Many NAS devices can act as VPN servers, allowing secure remote access to the local network and its resources.

7. Download Manager

NAS systems come with tools for managing downloads, including BitTorrent clients and usenet downloaders. This can help you centralize file acquisition.

8. Time Machine Backup for Macs

You can use a NAS to serve as a Time Machine backup destination for Mac computers. This is great if you need easy and quick backup functionality.

9. Personal Wiki or Knowledge Base

Using applications like DokuWiki, a NAS can host a personal or team knowledge base, centralizing information and documentation.

10. Game Server

Some NAS devices are powerful enough to host game servers for games like Minecraft or Counter Strike. This gives you a dedicated platform for multiplayer gaming.

11. Home Automation Hub

A NAS can also integrate with smart home systems. This also serves as a central controller for various IoT devices and automation scripts.

12. Plex Media Server

While media streaming is a common use for a NAS, running a Plex server on a NAS takes it even further offering you a Netflix style experience for your personal media library.

13. Photo and Video Management

Advanced NAS systems sometimes come with AI powered photo and video management tools, automatically organizing and tagging media files. This can save you hours of your time.

14. Blockchain Node

Some people use NAS devices to run full nodes for certain cryptocurrencies, contributing to network decentralization.

15. Remote Development Environment

If you’re a developer you can use a NAS as a remote development environment, accessing coding tools and resources from anywhere.

Things to Think About When Choosing a NAS

Storage Capacity: Think of your current storage needs and double it. Data tends to rise up in size. That’s why nowadays a 5TB external hard drive can’t offer you much room.

RAID Support: For data redundancy and improved performance.

Processor and RAM: They affect the NAS’s ability to handle multiple tasks and users at the same time. If you have a big family you might want to get a NAS with a more expensive CPU and more RAM.

Operating System: Some NAS devices run some closed source OS, but others come with open source options like TrueNAS. If you know what you’re doing the TrueNAS ones are almost always a better option.

Expandability: Look for models that give you easy drive upgrades or expansion.

Energy Efficiency: Think of power consumption because a NAS will stay plugged in and running 24/7.

Security Features: Encryption, user access controls and secure remote access are super important.

The idea of Network Attached Storage has evolved from simple file servers to flexible and powerful systems that can form the core of home and business networks. With applications ranging from basic file storage to complex virtualization and automation tasks, NAS devices give you a flexible and scalable solution for modern data management and more.
