The Logic Behind My NAS Strategy
Building a homelab is often a balancing act between "cool tech" and "practical utility." For my storage needs, I decided to take a pragmatic, long-term approach.
The Goal
I needed a system that could serve as a reliable media archive for movies, TV shows, and music, accessible to the entire family. The key requirements were:
- Low Maintenance: I don't want to spend my weekends fixing a broken array.
- Flexibility: The ability to add mismatched drives as my budget allows.
- Longevity: A system that can scale for the next 10-20 years.
The Setup: Unraid
I chose Unraid over TrueNAS or a standard RAID setup for one main reason: Flexibility.
With Unraid, I can mix and match drive sizes. I can start with a 4TB and an 8TB drive, and add a 12TB drive later without rebuilding the entire array. This "grow as you go" approach is perfect for a home environment where budgets fluctuate.
Separation of Concerns
A key architectural decision was to separate Compute from Storage.
- Compute: My Beelink SER5 runs Proxmox and handles all the active workloads (VMs, Docker containers, game servers).
- Storage: The Terramaster NAS (running Unraid) does one thing and does it well: it stores files.
This separation means I can reboot my Proxmox host to test a new kernel without taking down the family media library. It also means the NAS CPU can be low-power and efficient, as it doesn't need to transcode video or compile code.
The "No Parity" (Initial) Philosophy
Controversially, I started without a parity drive. Why?
- Data Criticality: My media library is replaceable. If a drive dies, I lose some movies, not family photos (which are backed up to the cloud).
- Cost: Parity requires your largest drive to be "wasted" on protection. In the early stages, I prioritized usable capacity.
As the array grows to 30-40TB, I plan to add a parity drive to save the hassle of re-ripping media, but for now, raw storage is king.
Looking Ahead
This setup is designed to be boring. Ideally, I won't think about it at all. It just sits there, quietly serving files, ready to accept a new hard drive whenever I find a good deal.
