TrueNAS Scale vs Unraid: I ran both for a month, and the winner wasn't what I expected

Published Sep 30, 2026, 12:31 PM EDT Umair Khurshid is a technology writer and developer with a strong focus on Linux, FreeBSD, cloud infrastructure, and automation. Before focusing on writing, Umair worked as a developer and DevOps engineer building and automating cloud-native systems. I went into my TrueNAS Scale versus Unraid test with a pretty strong assumption about how it would end. TrueNAS Scale had almost everything I normally look for in a homelab server. Unraid looked more convenient, but I expected that convenience to come with compromises I would eventually find annoying. Then I actually used both for a month. I spent enough time with Unraid’s free trial to get past the initial impression and use it for the things I normally expect a home server to handle. By the end, I was leaning toward Unraid, which was not the conclusion I expected when I started. The reasons had surprisingly little to do with which platform had the more impressive storage technology. TrueNAS Scale gave me the storage experience I expected ZFS is still the reason I would choose TrueNAS The biggest difference became obvious as soon as I started working with storage. TrueNAS Scale is built around OpenZFS, so snapshots, checksumming, compression, and replication are all central to the experience. If I want a server where storage integrity and management are the main priorities, that is a very compelling foundation. Credit: TrueNAS Unraid’s traditional array uses parity to reconstruct a failed disk, while ZFS can verify stored data through checksums and repair corruption when redundant data is available. Unraid now supports ZFS pools for cache and other storage, so the gap is not as simple as it once was, but the main array remains a different storage design. On TrueNAS, RAIDZ expansion allows disks to be added to an existing RAIDZ vdev. That makes the old criticism that a ZFS pool has to remain fixed forever inaccurate, but it still requires more planning than simply adding another independent disk to an Unraid array; the difference is smaller than it used to be. That is where I would still choose TrueNAS. When I am thinking primarily about data protection, storage architecture, and long-term management of a ZFS pool, TrueNAS gives me the tools I actually want, but the problem is that my homelab is not only a storage system. Unraid made more sense once I started running services Docker and virtual machines changed the equation The biggest surprise came from using both systems for everyday workloads rather than treating them as storage appliances. Unraid’s Docker management makes it easy to deploy services, change their configuration, and keep track of what is running. You can configure an image, ports, environment variables, and storage paths from the web interface and get back to whatever else you are doing. Its Community Applications ecosystem also makes discovering and deploying common services straightforward. Unraid Unraid is a Linux-based NAS operating system that focuses on storage capacity through its parity system instead of traditional RAID. TrueNAS Scale has closed some of the gap here. TrueNAS has moved its Apps backend from Kubernetes to Docker and added support for deploying Docker images through its interface or Compose YAML. That was a significant change from the earlier SCALE app experience, and it means comparisons based on the old Kubernetes-based system are already outdated. Even with that change, I found Unraid more convenient for a home server. The difference is not whether Docker works but how much attention you have to give the platform while running it. The same applies to virtual machines. You can run a Linux VM alongside containers and storage services without making virtualization feel like a separate project, and that matters to normal users because a homelab server is often doing several jobs at once. After a few weeks, I stopped thinking about which platform technically supported a particular workload. Both could handle the workloads I cared about. I started paying attention to which one made the machine easier to live with, and that was where Unraid began pulling ahead for me. Unraid’s hardware flexibility is still hard to ignore Adding random drives is exactly what a homelab often needs The clearest practical difference appeared when I thought about how I actually buy storage. With ZFS, the pool architecture matters. RAIDZ expansion has made adding capacity easier, but I still have to think about the vdev and how the new disks fit into the existing pool. That planning is worthwhile when I am deliberately building a storage system. Unraid is much more comfortable with the kind of hardware accumulation that happens in a homelab. I can have a 4TB drive, two 8TB drives, a 12TB drive, and later add a larger disk as long as the parity requirements are satisfied (the parity disk needing to be at least as large as the largest data disk). There is a tradeoff, though, and this is where I think comparisons between these systems often become misleading. Unraid’s main array is not a ZFS pool with parity bolted onto it. Its performance characteristics are different; parity-protected writes involve additional read and write operations, while the main array is designed around individual disks rather than striping data across them for aggregate performance. A cache pool can take over write-heavy workloads and can use Btrfs or ZFS, which makes Unraid considerably more flexible than the old “XFS disks plus parity”. That cache architecture ended up making more sense to me than I expected. Fast SSD or NVMe storage can handle Docker containers and VMs while the larger array provides bulk storage. I could build the server around the hardware I already had and expand it gradually. That is a very practical advantage when the server evolves over several years instead of being purchased as one perfectly planned system (especially given inflation). After a month, I would probably pay for Unraid The convenience became more valuable than I expected The funny part of this experiment is that I started the Unraid free trial expecting to prove that I did not need it. Instead, I spent enough time with it to understand why people are willing to pay for it. The licensing is part of that decision. Unraid’s current licensing tiers limit the number of attached storage devices differently, so the license becomes relevant if the server grows beyond a small collection of drives. I might consider buying Unraid after its move to Fedora. I want to see how that transition goes before committing to a license, especially after spending a month testing the platform. The fact that I went from expecting to dismiss Unraid to seriously considering buying it probably says more about the experience than any benchmark could. Which one makes more sense for you? The choice ultimately comes down to whether you want the storage system itself to be the focus or want a more general-purpose server that happens to provide storage as one of its main jobs. If you are building a homelab around a mixture of storage, containers, virtual machines, and gradually expanding hardware, Unraid is the one I would recommend trying first.
