I meant 2 disk access, some or another. From what I read they would never be simultaneous anyways.
Either way, this would be useful (actually IS, some solutions do this) in the Business Intelligence field. But the whole point of keeping everything in memory is moot when you have petabytes of information that you need to process during your ETL. What matters in this database is, how well does it behave in a cluster and how would it handle concurrency (ACID? Eventually synchronized?).
I doubt this is all that useful for common DB applications like websites and the like. Relational DB's have been proving to be enough for everything (ex: Youtube uses mysql shards - or used to) purely web related for a while now, I doubt this is a gamechanger at all.
