TrueNAS
Reddit take
AI summary of the Reddit excerpts below — not a quote
TrueNAS is a highly regarded, industry-grade storage platform frequently used in homelab and data hoarding environments for its reliability and ZFS-based features. While it is praised for its flexibility in managing network shares, backups, and containerized applications, it is noted for having strict hardware requirements and a steeper learning curve than consumer-grade alternatives.
Pros
- Versatile support for network shares, VMs, and Docker containers
- Solid, industry-grade reliability for data backups and large-scale storage
- Supports advanced storage configurations including RAIDZ2 and iSCSI targets
- Effective hardware passthrough capabilities for HBA and NVMe drives
Cons
- The boot device is restricted; storage capacity on the installation disk cannot be used for data or apps
- High RAM requirements due to ZFS caching, which can consume the majority of available system memory
- Discourages the use of USB flash drives or SD cards for boot media, often requiring a dedicated M.2 or SATA slot
- Potential for VM corruption during major software transitions or version switches
Caveats
- Not considered a 'low skill' solution compared to consumer NAS operating systems
- Running TrueNAS as a VM typically requires dedicated hardware passthrough for stability
- The installation UI is occasionally cited as being less intuitive than the main management interface
Best for
- Users requiring robust ZFS-based storage for large datasets
- Homelab enthusiasts running services like Plex, Nextcloud, or Jellyfin
- Environments where data integrity and industry-standard backup tools are a priority
Avoid if
- You have limited drive slots and cannot spare a dedicated disk solely for the OS boot
- You are looking for a simple 'plug-and-play' experience with minimal technical configuration
- Your hardware has very limited RAM

If not, start with installing https://www.truenas.com/ which will allow you to create network shares, VMs, Docker Containers, etc.
I'm building a TrueNAS setup and trying to figure out the best place to keep it.
Since TrueNAS doesn’t allow using the boot device for general storage, I chose to boot from mirrored USB flash drives.
However you typically trade the flexibility of something like truenas or unraid for whatever the devices OS allows you to do.
I used a truenas VM for my NAS
This rack is my home one and since buying it that top 4u unit is a Trunas server that runs my apps and Plex server with 64TB of usable storage.
Looking at DIY and "single disk" solutions TrueNAS while free and industry grade isn't quite "low skill".
I use to perma seed over 100TB of documents and content that I felt was important but when truenas made the switch, my vm's got corrupted.
forced me over to TrueNAS, which I know is solid and software-wise, have had no complaints.
Not to mention that Truenas is easy to learn and get started with, I feel like the UI for installing the system itself gives the whole system a bad rep.
