What 3-drive configuration for a TrueNAS Scale server? (alien.top)

I have a Beelink EQ12 Pro where I can put a total of 2x2TB NVMe SSDs + 1x4TB SATA SSD (not sure if more is feasible according to Beelink's description but it is enough for me right now).

I'd like a configuration where I can lose and replace one drive without breaking anything, hotswap not needed. What would be an adapted strategy for that in terms of drive capacity, partitioning and ZFS pool? 3x2TB even if two are M.2 NVMe and one is SATA? 2x2TB + 1x4TB? Something else?

I don't know if I would combine NVMe and SATA SSD's.
You need a boot drive as well, so one will be the boot drive, then 2 for the storage array (assuming you don't boot from USB or something)

I personally would boot from the SATA SSD, then mirror the storage disks if redundancy was needed, or stripe if you don't care for redundancy.

Didn't think that way around but this can probably work pretty well :) What about the remaining space on the SSD then? May it be partitioned so I have 3x2TB with 2x2TB of NVMes and parity on the 2TB SATA SSD?

That’s something that I’ve never tried before.

I’m more so worried about performance loss having a SATA SSD mixed with an NVMe in parity. You’re talking a 500MB/s SATA SSD vs a 3000+ MB/s NVMe.

Yeah you're right, that's why I was imagining putting only the parity bits on the SATA drive, so ZFS can do it's calculation after I'm done with my data operations on the NVMes. Guess I'll have to dig deeper in TrueNAS and ZFS config :)
