I'm aware of that, but I have quite low IO throughput requirements
and the use of a RAID is more important than a little throughput
degradation.

Oh yeah, I forgot to mention I only looked at non-x86 boards and things
using little power.

I am using stock x86 boards for normal file servers (but wouldn't call thosee
NAS). Those often come with lots of SATA ports and space for several NVMEs
(either on the mainboard or via PCIe adapters).
