Single root folder but with multiple performance tiers

TrueNAS General
1

Hello, I am new to TrueNAS, and I have been wondering if Truenas can do the following:

Create a SMB/Apple Share that has multiple tiers of raid performance behind it. Main reason, I do lots of video editing, and would like to store the larger 4k files on SSD/NVME tier, and keep the smaller files on the HDD Tier. I don’t mind if it is a manual or scripted method (ie files over 6GB go to the the SSD/NVME Tier) I did read something about Bcachefs, but it looks like it is not ready for TrueNAs yet? Any other options? I never want the 4k files to move to a slow tier if they are not used. My work is too sporadic, needing old files all the time.

TrueNAS is ZFS Only - I don’t think there is going to be support for other file systems any time soon. Unfortunately ZFS doesn’t have a tiered storage solution and there doesn’t seem to be any plans in that regards.

You can create two pools, a HDD only pool and a SSD only pool. But you would have to manually copy files between those two.
