- DaiPlusPlus 5y agoThe Wikipedia article on _IBM i_ (nee OS/400) is light on details, but eventually it links to https://en.wikipedia.org/wiki/Single-level_store https://en.wikipedia.org/wiki/Single-level_store and this part is prophetic: > IBM's design of the single-level storage was originally conceived and pioneered by Frank Soltis and Glenn Henry in the late 1970s as a way to build a transitional implementation to computers with 100% solid state memory. The thinking at the time was that disk drives would become obsolete, and would be replaced entirely with some form of solid state memory. ...so they were literally 50-60 (maybe 70-80 at this rate) years ahead of their time.
