Methodology
Write amplification cannot be read directly from a
browser. This estimation writes a known amount of data at multiple block sizes and measures the time
overhead ratio between small-block and large-block writes. SSDs with high write amplification show
disproportionately more overhead at small block sizes because the controller must read-modify-write
entire NAND pages. The WA factor is computed as (small_block_time / large_block_time) / (large_block / small_block)
normalized against a baseline. Values near 1.0× indicate low amplification; values above 2.0×
suggest significant amplification typical of SSDs under random workloads.
