Network Attached Storage (NAS) is a storage device connected to a network that allows multiple users and devices to store, access, and share data over the network. NAS devices are typically dedicated file servers that provide centralized storage and file-sharing capabilities for multiple clients and servers on a network.

NAS devices can be accessed using various protocols such as NFS (Network File System), SMB (Server Message Block), AFP (Apple Filing Protocol), and FTP (File Transfer Protocol). They can also offer additional features such as remote access, data backup and synchronization, media streaming, and integration with cloud storage services.

NAS devices come in various sizes, from small home-use devices to large enterprise-level systems that can store petabytes of data. They can be configured with different levels of redundancy and data protection, such as RAID (Redundant Array of Independent Disks) and backups, to ensure the integrity and availability of the stored data.

Hardware: NAS devices come in various shapes and sizes, from standalone devices to server-grade systems with multiple drive bays. Typically, they have an Ethernet port to connect to the network and run a dedicated operating system that handles file storage and access.

Installation and configuration: Once connected to the network, the NAS device needs to be configured to create storage volumes, set up user accounts and permissions, and configure other settings, such as network access protocols.

File sharing: Users and devices on the network can then access the NAS device as a shared storage location. They can connect to the NAS using various protocols such as SMB, NFS, FTP, or HTTP and access files and folders as if they were stored locally.

Backup and synchronization: NAS devices often have built-in backup and synchronization features, allowing users to automatically back up their data to the NAS or sync files between multiple devices.

Security: NAS devices typically offer various security features such as user authentication, access controls, encryption, and firewall protection to ensure the privacy and security of the stored data.

Overall, NAS provides a convenient and cost-effective way to store and share data over a network, making it an ideal solution for homes, small businesses, and enterprises.


The three types of network-attached storage (NAS) are:

Desktop NAS: These are compact and relatively affordable devices that can be easily placed on a desk or shelf. They are designed for personal or home use and typically have fewer drive bays and less powerful processors than larger NAS devices.

Rackmount NAS: These devices are designed to be mounted in a server rack and are typically used in small to medium-sized businesses. They offer more drive bays and powerful processors than desktop NAS devices and can support multiple users simultaneously.

Enterprise NAS: These are large-scale devices designed for large businesses or organizations. They offer high storage capacity and high-performance features such as redundant power supplies, multiple processors, and advanced data protection and management features. They can also be easily scaled up to meet the growing storage needs of the organization.

  1. Centralized storage: With a NAS, you can have all your files in one centralized location. This makes it easy to access and share files across multiple devices and with multiple users.
  2. Data backup: A NAS can also be used as a backup solution for your important files. With features like RAID, you can ensure that your data is protected against drive failures.
  3. Remote access: With a NAS, you can access your files remotely from anywhere in the world. This is useful if you need to access your files when you are away from home or office.
  4. Media streaming: Many NAS devices come with media streaming capabilities. This means that you can store your movies, music, and other media files on your NAS and stream them to your TV or other devices.
  5. File sharing and collaboration: A NAS can also be used for file sharing and collaboration. You can set up different user accounts and permissions, allowing multiple users to access and collaborate on files.
  6. Security: A NAS can be a secure way to store your sensitive files. With features like encryption and user access controls, you can ensure that your files are protected against unauthorized access.

Overall, a NAS can be a valuable addition to your home or office network, providing a range of features beyond just storage. It can improve efficiency, productivity, and security, and make it easier to access and share files across multiple devices and users.


Yes, NAS HDD (Network Attached Storage Hard Disk Drive) can be used on a desktop computer. NAS HDDs are designed for network-attached storage devices and optimized for continuous operation and reliability in a RAID (Redundant Array of Independent Disks) configuration.

However, they can also be used in desktop computers as long as the computer’s motherboard or RAID controller supports the specific NAS HDD interface (usually SATA or SAS) and the required RAID configuration. It’s worth noting that NAS HDDs may have slower write speeds compared to regular desktop HDDs, but they are often more durable and reliable for long-term use.

Choose the right hardware: The first step in setting up a home media server is to choose the right hardware. You can use an old desktop computer, a dedicated media server like the Synology DS220+, or even a Raspberry Pi. Make sure the hardware has enough storage space to store all your media files.

Install the media server software: Next, you need to install the media server software on your hardware. Some popular media server software options include Plex, Emby, and Kodi. Choose the one that suits your needs and install it on your hardware.

Organize your media files: Before you can start streaming your media files, you need to organize them. Make sure all your media files are in a single folder and that they are named correctly. This will help your media server software to recognize and categorize your files correctly.

Set up your media server: Once you have installed your media server software and organized your media files, you need to set up your media server. This involves configuring your media server software to recognize your media files and to make them accessible to other devices on your home network. You may need to create user accounts for family members and set up access permissions.

Stream your media files: With your media server set up, you can now start streaming your media files. You can access your media server from any device on your home network, including your smart TV, laptop, tablet, or smartphone. Simply open the media server app on your device and start browsing your media files.

Optional: Remote access and sharing: If you want to access your media server from outside your home network, you can set up remote access. You can also share your media files with friends and family by creating guest accounts and setting up sharing permissions.

Setting up a home media server requires some technical knowledge, but it’s a great way to consolidate all your media files and make them accessible to all the devices in your home. With a little bit of effort, you can set up your own media server and enjoy your favourite movies, TV shows, and music from anywhere in your home.
