I can’t say how your firmware will recognize a PCI-e to NVME, but as long as your aren’t chasing boot time records a SATA SSD should be more than sufficient for boot. You could just use the NVME for speed.
Another option would be to set up 6 SATA SSD drives in there with ZFS2. The striping and read-write speeds should significantly fill the SATA buffer of 6gbps. Due to the striping, you might actually avoid filing the read buffer and be about to sustain a longer high write speed.
The drive farm is also super viable. I have a 6-port board and a SAS card installed giving me 10 or 14 ports, I can’t recall. I have a similar strategy as I described, but I’m only using it for a NAS. I looked into getting a 12-port board, but used it was still $350. It makes more sense for me to buy another SAS card instead.





I was doing okay with 4-5 tabs on a core 2. Used Facebook as a test.
