Disk setup for OS install

I’m installing SCALE 24.10 on a server, and have either a Dell Integrtated SD Card module or a pair of SATA SSD’s for OS installation. The DISD module basically raid-1’s a pair of 32GB SD cards, but I have a couple of 128GB SSD’s too. Should I wish to install to these, should I similarly set them up as a RAID1 pair in the Bios, or just leave them as AHCI SATA devices and allow TrueNAS to sort them in to ZFS pools?

I assume these would be preferable to the SD Cards?

The latter.

Correct.

Thank you, Ambassador Kosh.
