2R: Efficiently Isolating Cold Pages in Flash Storages
Summary: Introduces 2R, a statistics-free two-region FTL isolating cold pages to reduce garbage-collection relocation without workload statistics. 2R-FIFO avoids false-cold victims, halves write amplification versus 1R-Greedy, and achieves over 4× gains near full capacity.
