Saturating modern SSDs is not that hard, if datastream is constant. Write performance usually degrades rapidly after couple of hours/days, once caches are filled and fragmentation grows.
But I totally agree modern SSDs will cause shift in computer and software architecture. Dealing with async disk IO is very frustrating.
