A new research paper introduces the NoWA write pattern, which guarantees a write amplification factor of exactly one on standard solid-state drives by aligning application-level data placement with the hardware's internal garbage collection. By organizing data into blocks that are invalidated and discarded in bulk, the technique prevents the drive from moving valid pages internally even at full capacity. Developers note that this breakthrough in storage optimization could pave the way for a new class of highly efficient database systems.
