摘要：

Write amplification is a measure of garbage collection efficiency and a key objective to minimize for NAND-flash memory based solid state drives. Prior works on analytical modeling of write amplification tend to fall short of the promises to offer more insights than simulations due to their complexity. This paper derives a simple formula to predict write amplification for practical skewed write traffic, which became recently known to closely follow Zipf's law.
