I've installed an extra 500GB SSD to my server that will only be used as the disc for a single VM; it won't be utilised for cache, appdata, or anything else.

Is it better to set it up as a cache pool device and use it to store only one vdisk file?

I'm hoping to receive the greatest possible result.

Or should I connect the disc to the VM directly? (Can I do this if the controller is a sata controller with other array discs attached?)

I'm assuming this is Hyper-V? I'd go VHDX. Pass-through used to be better for performance but that's a moot point now with VHDX.
