Yeah per your edit that'd be for 256GB RAM which puts that into serious dollar category. For comparison I checked what AWS asks for for the same spec and that'd be $4616/month (for a db.m8gd.16xlarge), and that doesn't even yield you an actual NVMe. You can of course build the same for cheaper on Hetzner but again then you're on the hook also for the operations of the thing, which at that size is possibly non-trivial.
