I do this with ProxMox and a passed through AMD RX580 and it's working fine, but the disk performance is terrible, even worse than I'd expect for the hard drive it's on. Luckily that doesn't matter much for gaming. The Proxmox wiki has great resources on GPU passthrough, but you may have to install a kernel mod for the AMD gpu not to take the host down when the guest powers off. I haven't been able to do this with VMware ESXi (I've tried); I forgot if it worked in unRaid or not (But it should, in theory).

Is it possible to pass though a hard drive directly, like you do with the GPU?

  Yes. If it's not used by the host at all.

  Not with Proxmox, no. You can use a PCIe-Sata card and pass that through if you have the slots available.
