I need a low power way to add sata ports to my unraid VM on Proxmox. I am passing through the onboard sata now but I need more. I have been reluctant to use a HBA due to power use as I am trying to keep this server as low power as possible(at least with idle).

I was originally thinking of using a dual m.2 nvme pcie card with 2x 1166 ASM m.2 sata adaptors for a low power sata expansion. My problem when testing with a 6x sata pcie expansion card(1166 asm) the card shared the ahci driver with the onboad sata that is running the proxmox os making it really hard to blacklist the expansion card drivers so proxmox can never load the disk on the expansion. I am hoping a proper hba would get around this.
