BENCHMARK MATRIX
────────────────
  A. Sequential Throughput : read/write × QD{1,32} × nj{1,4,8,16} × 1M  (16 jobs)
  B. Random IOPS          : randread/randwrite × QD{1,4,16,32} × nj{1,8,16,32} × 4K  (32 jobs)
  C. Latency              : randread/randwrite × QD1 × nj1 × 4K  (2 jobs)
  D. Mixed 70/30          : randrw × QD16 × nj{1,4,8} × 4K  (3 jobs)
  Total: 53 jobs × 3 runs = 159 runs per layout
