My advice, skip the TrueNAS and go straight to FreeBSD. It's a simple operating system to maintain and it requires minimal setup to use as a NAS.

I think this is a valid approach, especially for the audience of Hackernews.

But I'd be a bit worried about the availability of drivers for much of the hardware found on this particular motherboard.

I’ve been pretty happy with taking a Terramsater F4-425 Plus and putting Linux on it. I feel like the mini ITX market for motherboards is just too niche. If you want something small, buy an off the shelf NAS. If size is not an issue, buy a case that can hold a full sized motherboard and lots of disks.

I just purchased one of these on BF sale. How hard is it to install Truenas?

Is this rage bait?

TrueNAS isn't even FreeBSD any more, it's Linux based now sadly

Then migrate straight to Linux

It's frustrating when a comment is both needlessly belligerent flamebait AND wrong about electricity prices in the US. I guess that's what makes effective flamebait

German electricity prices are around €0.38/kwh based on my quick googling which is roughly $0.44/kwh. I pay $0.12-0.13/kwh in the US so I’m at least right factually up to rounding.

Wrong. I pay €0,23/kWh, so do your homework.

What exactly is failing in Germany, and why is it important in this context?

Sorry but this is a deeply flawed analogy.

They have failed to have a sensible industrial and energy policy, leading to around net 0 GDP growth since 2019. I’m sure for the degrowth elites though this is not a failure it is working as intended.

That's only for ZFS deduplication which you should never enable unless you have very, very specific use cases. For normal use, 2GB of RAM for that setup would be fine. But more RAM is more readily available cache, so more is better. It is certainly not even close to a requirement. There is a lot of old, often repeated ZFS lore which has a kernel of truth but misleads people into thinking it's a requirement. ECC is be…

There are a couple recent developments in ZFS dedup that help to partially mitigate the memory issue: fast dedup and the ability to use a special vdev to hold the dedup table if it spills out of RAM. But yes, there's almost no instance where home users should enable it. Even the traditional 5gb/1tb rule can fall over completely on systems with a lot of small files.

I think the asterisk there is that the special vdev requires redundancy and becomes a mandatory part of your pool.

Some ZFS discussions suggest that an L2ARC vdev can cache the DDT. Do you know if this is correct?

I do like to deduplicate my BitTorrent downloads/seeding directory with my media directories so I can edit metadata to my heart's content while still seeding forever without having to incur 2x storage usage. I tune the `recordsize` to 1MiB so it has vastly fewer blocks to keep track of compared to the default 128K, at the cost of any modification wasting very slightly more space. Really not a big deal though when tal…

Have you considered "reflinks"? Supported as of [OpenZFS 2.2]( https://github.com/openzfs/zfs/pull/13392 ). Haven't used them yet myself but seems like a nice use case for things like minor metadata changes to media files. The bulk of the file is shared and only the delta between the two are saved.

Neat; will look into this. My setup is several years older than this, predating even FreeBSD's move to OpenZFS, and I just haven't touched the config of it since then since it works flawlessly (and since I already bought the RAM lol)

Obligatory comment every time one of these threads comes up that Synology, sure, the hardware is a bit dated but… as far as set and forget goes: I’ve run multiple Synology NAS at home, business, etc. and you can literally forget that it’s not someone else’s cloud. It auto updates on Sundays, always comes online again, and you can go for years (in one case, nearly a decade) without even logging into the admin and it j…

Synology also has a bit of a software moat with its BTRFS-backed SHR implementation. You can throw in drives of arbitrary size and it'll automatically maximize the available free space. ZFS can't do that, though AnyRaid should make it possible in the future: https://docs.hexos.com/blog/2025-05-22.html

Plus, DSM has a spectacular web interface.
