The Need for a New I/O Model

Summary: Argues the classic two-level external-memory I/O model (fixed-size blocks, single-I/O cost) is ill-suited for SSDs because its assumptions of symmetric read/write costs and single outstanding I/O no longer hold. Calls for a new model capturing read/write asymmetry and device-level parallelism. (summarized by gpt-5-mini on Feb 09 2026)
