Regarding DDBB performance, I/O and SSD disks

Hi all
I would like to virtualize a physical Linux Server with a Firebird database into proxmox
I know that DDBB usually needs lots of I/O.

So I thought I should have a SSD drive to put the DDBB (because the performance)

I think I have to options:
1. use KVM, create a filesystem onto SSD drive and add partition to VM using virtio driver
2. use containers and bind-mount the device into container

Which would be better?
Any advice would be really appreciated
Thanks
