Over the years, I have tried enough NAS operating systems to know that most of them are designed to cater to a particular kind of user. Some are made to be beginner-friendly, while others are better suited for experiments. But all of them want to lock you down to their own ecosystem, which is especially true for pre-built NAS models that you get off the shelves. When you want to try something even mildly unconventional, you will start to notice the constraints.
Ubuntu Server, on the other hand, doesn’t behave like it’s trying to box you in. It feels like a real operating system for your NAS that respects your intentions. It works hand in hand with you, not against you. And here are a few reasons that work in its favor.
You’re not locked in
The vendor’s whims don’t work here
Most NAS operating systems set up the rules and boundaries for you — similar to how Apple decides what you can do on your phone and how. They dictate which apps you can run, which filesystems will work trouble-free, and when you get updates. That’s not the case with Ubuntu Server.
You can pick up the hardware you want, design your own storage, choose whichever filesystem suits you the best, and run whatever app or service you need. Without any proprietary tech locking you in, you can easily switch hardware by simply using the same drives. This way, your NAS won’t go obsolete after a fixed term when the company decides to stop supporting it.
4 reasons why you shouldn’t use ZFS as a beginner
Despite all its perks, ZFS has a couple of deal-breaking flaws
Fixes are easier
Things breaking don’t leave you scrambling for solutions
A big downside of working with a closed operating system is that a lot of system information is hidden and opaque. It’s fine when everything is running smoothly, but a single instance of something breaking will reveal how difficult troubleshooting can be when you can’t even see the complete picture.
Ubuntu Server is the opposite of opaque. It wants you to see the entire dashboard; nothing is hidden from you — from system logs to service packages — and the information is both documented and presented well. You can easily investigate and fix issues when a disk starts to act up instead of waiting for a patch to arrive.
More importantly, the Linux ecosystem ensures that you’re not alone troubleshooting — someone, somewhere, has faced and fixed the exact same issue.
I use Proxmox Backup Server to save my VMs and LXCs to TrueNAS over NFS – here’s how
It’s a fully-automated backup procedure that saves my VM and LXC data to my trusty NAS
It can run basically anything
Rarely does it say no
All mainstream brands like Synology, QNAP, and Terramaster come with their own app stores with their ‘approved’ list of apps that you can install and run. But once you start to dig a bit deeper and want something obscure, chances are you won’t find it there, or it would need a tiring workaround that may not even be worth the effort.
Ubuntu welcomes everything with open arms. You could run Docker containers, manage them with Kubernetes, run custom scripts to manage your blog, sync notes, manage cameras, and whatnot. Not just customer-friendly apps — you can run real services exactly the way you want. It truly makes your NAS feel like a home server and not just a storage device.
Tune the performance
Yeah, you can tweak that too
NAS enclosures in general, and their operating systems, are tuned for average household users, which is fine until you demand a bit more performance headroom with things like SSD caching, ZFS, or better 2.5GbE or even 10GbE LAN ports. Ubuntu Server doesn’t keep you from performing tasks like tweaking kernel parameters, enabling jumbo frames, fine-tuning SMB settings, or adjusting ZFS cache.
You don’t have to rely on or wait for the NAS maker to open up these advanced settings. And these tweaks are necessary since they don’t just help with speed but also ensure system reliability even under heavy workloads. Once you’ve tasted this level of control, going back will feel restrictive.
6 small upgrades that make a big difference to your NAS performance
Turns out, little upgrades do add up!
Long-term stability
And no stagnation
A lot of NAS OS makers follow long update cycles, especially for major updates. While it sounds nice on paper, it means living with older kernels for longer and sometimes even delayed security patches, especially for non–zero-day vulnerabilities. Ubuntu’s LTS releases strike a balance so that your system can stay stable even if it stays untouched for years, while still supporting new hardware and systems.
The security updates are much more predictable, and you always have the safety net of a massive package ecosystem. The OS doesn’t feel out of date even after years, nor do you need to wait months for basic improvements. This kind of stability and reliability alone is worth going with Ubuntu.

My Ubuntu system now boots faster and is much cleaner and better maintained.
It scales with you
Instead of holding you back
The humble two-bay NAS you set up at home eventually becomes the central machine that you rely on for backups, surveillance, media streaming, photo backups, running containers, and more. When your requirements grow over time, a lot of NAS operating systems don’t scale with you as seamlessly as you’d expect.
Ubuntu Server simply adapts to your needs. It makes it possible to move to new hardware, build another storage pool, switch your RAID setup, and whatnot — all without breaking your existing workflow. It can work as a simple setup for beginners to a full-blown home lab without forcing you to adapt to new UIs or ecosystems.
Conventional RAID 5 isn’t good enough — here’s what you should do instead
The ZFS-based RAID-Z1 is just superior to conventional RAID 5
An OS that respects your choices
Ubuntu Server isn’t the prettiest NAS solution, nor does it hold your hand like Synology’s DSM would. But for people who know what they are doing, it is the perfect solution that is meant to support you for a long time. It lets you fully take control of your data and the hardware, without hindering your workflow. Ubuntu gets you the freedom you need while being functional.
