Your NAS is becoming a single point of failure, and consolidating everything onto it is the reason why

At a glance:

• NAS devices like TrueNAS SCALE are powerful enough to run multiple services, creating single points of failure
• Consolidating home lab, media servers, and automation on one NAS increases downtime risk significantly
• Experts recommend keeping NAS focused on storage while using separate devices for other services

The modern NAS: more powerful than ever, but at what cost?

Running a network-attached storage (NAS) device on the LAN is a great way to start self-hosting content. Whether you're planning to save money by cancelling various streaming services, wish to take control of your own data and cease relying on cloud storage, or simply want somewhere to stash some backups, it can be difficult to resist the urge to run everything on the NAS. The problem with prebuilt turnkey enclosures of today is that they're powerful enough to run multiple services, allowing you to create your own streaming platform, collaboration suite, and more with the click of a few buttons.

Moving to DIY NAS operating systems like TrueNAS just makes matters worse. This is a compelling NAS OS with ZFS at its core and some impressive features to create the ultimate network storage device. Having used TrueNAS for years now, it's genuinely powerful, and I often recommend it to those who are ready to leave the clutches of a particular NAS brand. It also makes sense to some to run everything on the NAS. With enough computing power, TrueNAS can handle containers and virtualized instances, effectively transforming the NAS into a full-blown server.

But just because TrueNAS can run everything you need in a home lab, it doesn't mean you should. A NAS is no longer simply a low-powered server with disks. It's the one device responsible for preserving data, serving it across the network, and ensuring recovery is possible should something go wrong. The NAS should be able to store important data safely, provide reliable access, manage redundancy, support backups, minimize downtime, and reduce the chance of losing a single bit of data.

A home lab server is a little different. Docker can be wiped, a server rebuilt, a host OS recompiled, and experimentation hosted. A NAS is great at storing things, while a home lab server is more akin to a hobby box. It may seem like a good idea to consolidate everything onto a single machine, but that would actually open your entire setup to a high risk of downtime due to one system running everything.

The danger of feature creep: from storage to everything

This is where splitting things up comes into play for both the home lab and with a NAS. Keeping the NAS separate and just storing data ensures valuable resources are not wasted completing tasks that other hardware could do. Instead of putting all of your home lab and NAS eggs in a single basket, consider segmenting parts of your data center.

Here's why NAS is great for storing data and not running a home lab, too. Let's say your NAS is also your VM host, media server, automation hub (hello, Home Assistant!), DNS filter, and more. It's asking a lot from the hardware, and while it may be able to handle all of this, regardless of whether it's a custom TrueNAS setup or a prebuilt turnkey NAS from the likes of Synology, something could go wrong that affects the rest of the stack. A misconfigured container could fill an entire pool or dataset with nonsense, a reboot required for a specific app interrupts everything else, or an update could take down the entire system.

The consolidation trend has accelerated with TrueNAS SCALE, which now offers LXC-style container support. This brings it closer to Proxmox, the king of hypervisors for home use, allowing experimentation and powerful virtualization with relative ease. LXCs require less overhead compared to a fully blown VM due to sharing the host kernel, making it even easier to turn a NAS into a home server.

Now, instead of firing up self-hosted apps and services within virtual machines on TrueNAS, an LXC can be created per package. This aligns the OS more with Proxmox, keeping resource usage down without sacrificing capability. There's even GPU passthrough with Nvidia and other supported hardware, making it easier than ever to configure a TrueNAS system with running services and full graphics support.

Why specialization matters: storage vs. compute

The UI was also refreshed to stop it from appearing too enterprise-like and make it slightly more welcoming for beginners. But that's where people can take a wrong turn by choosing to run just about everything and the kitchen sink without considering any consequences.

First, it starts with Plex or Jellyfin. Then, Nextcloud is added further down the line to offer something in lieu of Microsoft Office 365. Suddenly, before you know it, the NAS is running a reverse proxy, password manager, DNS filter, and more. It's less about storing data and more about running all the self-hosted services you can find. That's not a dig at TrueNAS and other operating systems either, as it's great they're made in such a way that this transition can occur faster.

Once you've toyed around with dedicated servers within a home lab setting, you learn that storage should be boring. It should be something you set up and forget. The author notes they rarely check on their own NAS running TrueNAS, logging in once a month to check updates and drive health, with backups fully automated. This hands-off approach is exactly what storage infrastructure should embody.

The path forward: separation of concerns

You've seen takes elsewhere as well as right here on XDA about NAS being great for doing much more than storing files, but I'm here to ask the question as to whether it should be used for more than storing bits on spinning platters. It's not that NAS can't be used for running the home lab, Home Assistant, and everything else you can throw into the local cloud; it's just that there's usually a better way, which can consist of a compact mini PC or some other device.

TrueNAS SCALE is one of the best aftermarket NAS solutions around, and the author has relied on TrueNAS for years to keep data safe. It's rock-solid and worth checking out for pure storage duties. However, for the compute-heavy tasks of running home automation, media serving, and development environments, dedicated hardware provides better isolation, easier troubleshooting, and reduced risk of cascading failures.

The key insight is that while the technical capability exists to consolidate everything onto one NAS, the operational risk often outweighs the convenience. By treating storage as a specialized, mission-critical service and relegating experimental or volatile workloads to separate machines, users can achieve both flexibility and reliability in their home infrastructure.
