I don't think so, since you will always want to have your data in a consistent and current state, even if the computer, OS or whatever crashes. That is not possible with an in-memory database.

We have spent lots of time to research the fastest disc-access mechanism possible and we write every update back to the disc instantaneously.

Stored data is also getting more and more complex. There will always be people that want to store the maximum amount of data possible. If you raise the possible limits, people will come up with more complex applications. Huge applications will never be possible in RAM only.

Kind regards,
Carl
