select disk for host

[prox.mox.user]

Hello everyone, I use a translator. I hope the translator will convey the essence of my question correctly.
I plan to use about 40 virtual machines with high load on the disk subsystem. Based on this task, I need your advice.

1. Can I use a regular sata3 ssd for proxmox os, and nvme ssd for VMs? Will a regular sata3 interface limit the host system's performance of VMs with nvme?

2. I am ready to listen to your advice on finding bottlenecks and possible problems.

1. a) yes, b) no.
2. As there is no system yet there are even not any bottlenecks and problems also.
