Build Your Dream NAS: Power and Simplicity Combined

DIY NAS Builds Offer Ultimate Control and Cost Savings

Forget relying on cloud services or single, overloaded PCs. Building your own Network Attached Storage (NAS) system puts you in control of your data, offering enhanced reliability and flexibility. While pre-built NAS units exist, a custom build can be more powerful, upgradable, and surprisingly affordable, especially when you consider the long-term costs of cloud storage.

Why Build a NAS?

A NAS acts as a central hub for all your digital needs. It’s perfect for storing and streaming media with services like Plex, backing up your important files, and sharing data across multiple devices in your home. Unlike a gaming PC that might struggle to handle streaming duties while gaming, a dedicated NAS ensures smooth performance without impacting your main computer’s resources.

Customization is Key: The Hardware Breakdown

The journey to a custom NAS begins with choosing the right components. For a balance of performance, efficiency, and modern features, an Intel Core i3-12100 CPU is a strong contender. This chip excels at direct play and software encoding, and its integrated GPU with Quick Sync technology offers great power efficiency. Crucially, it features native AV1 support, a forward-looking feature that might become more important for video encoding in the future. While older, cheaper CPUs can handle basic storage tasks, they often sacrifice efficiency and modern capabilities.

For the motherboard, the Asus Prime B760M-D4 provides a solid foundation. Its 2.5 Gigabit LAN, good input/output options, and ample expansion slots in a compact Micro-ATX form factor make it a versatile choice. While it might only have four SATA ports, a Host Bus Adapter (HBA) card later in the build unlocks significantly more storage potential.

Memory capacity is more important than raw speed for most NAS tasks, especially if you plan to run virtual machines. The ability to upgrade RAM later via four DIMM slots offers future-proofing. However, the real cost and challenge in this build were the hard drives themselves. Global shortages have driven up prices and limited availability, forcing some creative solutions like sourcing drives from different locations.

Tackling Storage Challenges

The chosen drives were four 8TB Seagate IronWolf CMR NAS drives, totaling around $1,200 CAD. While Shingled Magnetic Recording (SMR) drives are cheaper and more power-efficient, Conventional Magnetic Recording (CMR) drives offer better performance during intensive write operations, which is important for data rebuilding in case of drive failure. For the operating system drive, a readily available 500GB WD Blue SSD was used, as its failure wouldn’t impact critical data.

Connecting all the drives to the motherboard requires an HBA card. An LSI card, known for reliability, can transform an unused PCIe slot into eight SAS ports, supporting both SAS and SATA drives. This bypasses the motherboard’s limited SATA ports and allows for massive storage expansion.

The case choice was the Jonbo N5, a large enclosure designed to hold up to twelve 3.5-inch drives. This provides ample room for future expansion, easy cable management, and convenient front-panel USB-C for fast data ingestion. A 500-watt SFX power supply from Silverstone was initially considered, but a slight compatibility issue led to switching to an MSI MAG A550 BN 550W unit, which fit well and supported standard ATX power supplies.

Software: The Brains of the Operation

After the hardware is assembled and recognized by the system, the next crucial step is choosing and installing the operating system. The primary options discussed were TrueNAS, Unraid, and Xpenology (or XOS). TrueNAS is often recommended for power users, while Unraid is known for its flexibility in handling different drive sizes. However, Xpenology, due to its user-friendly interface and ease of setup, emerged as the preferred choice, especially with access to a license.

Installing Xpenology involved flashing an installation image to a USB drive and booting from it. The process was straightforward, guiding the user through selecting the OS drive and creating storage pools. The system automatically configured a RAID Z1 (similar to RAID 5) setup, providing 40TB of usable storage with redundancy for one drive failure.

Overcoming Hurdles: Windows File Sharing and Tailscale

While the initial installation and setup of Xpenology were relatively smooth, the real challenge emerged when connecting to Windows PCs. Issues with Windows Credential Manager and SMB client configuration (specifically the security signature requirement) caused access problems. These issues, thankfully, were not with the NAS itself but with the Windows networking configuration. Resetting the SMB client configuration to disable the security signature requirement resolved the problem, allowing seamless access to the NAS shares.

To enable secure remote access without opening network ports, Tailscale was implemented. This virtual networking solution allows users to securely connect to their NAS from anywhere, offering peace of mind that data is protected and accessible without traditional security risks.

The Verdict: Is a DIY NAS Worth It?

Building a custom NAS involves a significant upfront investment, with this particular build costing nearly $2,000 (excluding the old drives). However, most of that cost is tied to the storage itself, which would have been an expense regardless of the solution. Compared to the ever-increasing costs of cloud storage subscriptions, a DIY NAS offers long-term savings and complete data ownership.

The process of building and configuring a NAS can be a rewarding learning experience, especially for those interested in networking and system administration. While the initial setup might present challenges, especially with software configuration and network troubleshooting, the flexibility and control gained are substantial. For tech enthusiasts looking to take charge of their digital lives, a custom NAS build is a powerful and cost-effective solution.
