The Roon Knowledge Base states that there is a size limit of 4TB on internal SSD storage.
Is this a fundamental constraint that is likely to remain in place for some considerable time or is there a realistic chance of it being increased in the near future?
Nothing stops you from using a spinning drive, but you can only fit a 2.5" drive in the NUC; the 3.5" drives require too much power to spin up. There is also a limit in the NUC chassis design that prevents fitting 15mm drives internally.
I don’t think anyone is making 2.5" drives larger than 5TB right now, and it’s a goofball 15mm drive.
If you want spinning big 3.5", you will need an external power supply, and then you can go USB.
I’m aware, but I won’t support them and they could break if I change around drivers in the future. We only test against the machines we support. We’ve made it clear that “other motherboards and options” are not supported now or in the future.
The 15mm height is there in the spec (https://kb.roonlabs.com/Nucleus_Manual), no mention of 8TB max, but next year, 16TB drives will probably fit into 15mm, so this is only the max for today.
@danny, So if you have a supported NUC in an HDPLEX Fanless chassis that can support pretty much any sizes drive i.e. with a 16TB spinning then - thats not supported. Rather disappointing IMHO but hey whatever it is, please just make it absolutely clear on the ROCK docs.
Nothing about drive data size limits there at all other than it can be SSD or Spinning and ANY SIZE
Internal storage (for music content) can be any size, and can be an SSD or a spinning disk, but note that the NUC kits tend to not support drives thicker than 15mm (not enough space inside the housing).
