We (databaselabs.io) did some customer dev tests for that exact product (databases with fast local hardware storage.) We found that almost all customers didn't care about getting that level of performance (enough to pay for it, anyway.) For ~99%, cloud-level shared storage is all they'll pay for. Finding the other 1% is a very expensive long-cycle sales and marketing proposition, so we decided to market cloud solutions to the 99%.
That said, we are equipped to run the 'fast dedicated hardware' solution (we come from a managed services background) -- just write me, pjlegato at databaselabs.io, and I'll get you set up.
