An Ultimate Guide to Unraid OS NAS

Network Attached Storage (NAS) has become an essential component for both home and small business (SMB) environments. With the need for data accessibility, backup, and storage scalability, a reliable NAS system is indispensable. Among the various NAS solutions available, Unraid OS stands out due to its versatility, user-friendly interface, and robust feature set. This guide will explore what Unraid OS is, the advantages of using an Unraid OS NAS, and provide a detailed look at the LincPlus Unraid OS NAS, along with a step-by-step guide on how to use it.

What is Unraid?

Unraid is a Linux-based operating system designed to provide an easy-to-use and flexible platform for building and managing a NAS. Unlike traditional RAID systems, Unraid allows you to mix and match drives of different sizes, which can be added to the array as needed. This makes it an ideal choice for users who want to expand their storage capabilities over time without being constrained by identical drive requirements.

Key Features of Unraid:

  • Flexibility: Add any number of drives, of any size, and mix and match them in your array.
  • Simplicity: Easy-to-use web interface for managing your storage, VMs, and Docker containers.
  • Protection: Offers parity-based protection to safeguard against drive failures.
  • Scalability: Easily expand your storage by adding more drives.
  • Virtualization: Run virtual machines (VMs) directly from the NAS.
  • Docker Support: Host Docker containers to expand functionality with apps like Plex, Nextcloud, and more.

FAQ: Unraid OS NAS

  1. What is Unraid OS and how does it differ from traditional RAID?

Unraid OS is a Linux-based operating system designed specifically for managing NAS devices. Unlike traditional RAID, Unraid allows you to use drives of different sizes and types in the same array. You can add new drives to expand your storage at any time, without needing to rebuild the array or match the sizes of existing drives. This flexibility makes Unraid ideal for users who plan to expand their storage over time.


  1. What are the hardware requirements for running Unraid OS on a NAS?

To run Unraid OS, you'll need a 64-bit capable processor (x86_64), at least 2GB of RAM (though 4GB or more is recommended), and a USB flash drive of at least 1GB to boot the OS. The LincPlus Unraid OS NAS, for instance, comes with an Intel Celeron J4125 processor and 8GB of DDR4 RAM, which provides ample performance for most home and small business applications. Additionally, having 2.5GbE network ports enhances data transfer speeds.

  1. Can I use different sizes and types of drives in my Unraid NAS?

Yes, one of the key advantages of Unraid is its ability to mix and match different sizes and types of drives within the same array. This flexibility allows you to maximize your storage capacity and easily expand your system over time without the need for drives to be identical. You can start with a few drives and add more as needed, making Unraid a cost-effective and scalable solution.

  1. How do I ensure my data is protected on an Unraid NAS?

Unraid offers several methods to protect your data:

  1. Parity Protection: By configuring one or two drives as parity drives, Unraid can recover data from a failed drive.
  2. Automated Backups: Set up regular backups using plugins or Docker applications to ensure your data is always backed up.
  3. SMART Monitoring: Utilize the SMART monitoring tools in Unraid to regularly check the health of your drives and receive alerts about potential issues.
  4. Redundancy: Keep multiple copies of important data across different drives or even in different locations to prevent data loss from hardware failures.
