Build A $129 Five-Bay NAS with Unraid

The previous document introduced two options for Unraid installation. This content will be combined with some of the accessories I currently have to build a five-bay NAS, and some Unraid OS features to talk about.

Introduction of the Hardware Currently Available

3.5-inch 5-Bay HDD Cage

My choice of hard drive cage here is cost-effective; the purpose is to get a great experience at the lowest cost possible

Power Cable Shorted

On a 20-pin or 24-pin connector, find the green wire, usually only one green one; if there are several, the power supply is a workshop factory production. You can find the thinnest green wire and short it to any of the black wires and see if there is any output.

Start To Configure UnraidOS

Configuring User Information

After the installation of Unraid is complete, there is only the root user by default, and no password has been set, which is a significant security risk.

Switch to the USER interface; you can see only the root user. Click on its avatar to enter the user edit screen, change the password and click CHANGE. Unraid will prompt you to log in again. Root is the most privileged user on the Unraid system and is also the login user of WebGUI, so make sure you remember its password.

Add/Manage User Permissions

Similarly, you can create users to manage user permissions when sharing

For security reasons, you should not use the root user when setting up share permissions and Docker applications.

Switch to the USER screen, click ADD USER, set the username, description, avatar and password, and click ADD to create the user.

Configuring Hard Disk Arrays

The array must be activated to enable other functions

Click “MAIN”

Create Unraid Disk

Configure disk

In the Disk 1 option, scroll down to select a drive to be added to the array. With the current hardware, I should be able to get a Disk5, but now, I only have two 4TB drives at disposal.

Create Unraid Disk

Once you have made your selection, click on the START button in Array Operation

Create Unraid Disk And Click Start

After a few seconds, the drive is mounted

The main concept behind the Unraid array is its ability to manage the aggregation of disk devices (JBOD) protected by a dedicated parity device. A parity device provides a way for you to rebuild data from a failed disk to a new disk. While it may seem incredible that a drive may back up other drives with more storage capacity than the parity, it can reconstruct lost data from a failed drive using binary logic called XOR (eXclusive-OR). Because hard drives store data as zeros and ones, when a drive fails, parity compares the binary data on all surviving drives and can infer the lost data to be reconstructed.

Create a Shared Folder


 Using Unraid Add User Share

Enter the appropriate information and select the appropriate disk

Using Unraid Select The Appropriate DisK

Set whether the folder is an SMB share folder

In summary:

There is much more to Unraid OS, and the benefits are clear: Flexibility and Scalability. Modular Unraid enables you to build the system you have always wanted using the preferred hardware, software, and operating system. I hope this system will meet everyone’s usage scenarios.
UnraidOS has been running quietly and stably on my ZimaBoard 216 for 48 hours without any discomfort!
