Converting from IOPS to MB/s

Conversion factors: from IOPS to MiB/s

Throughput is a function of Input/Output per second (IOPS) divided by (block size in bytes / 1024 bytes) x 64. Hence, larger block sizes will yield higher sustained data transfer.

clusterSize => multiplier
512 => 2048
1024 => 1024
4KiB => 256
8Kib => 128
16KiB => 64
23KiB => 32

Formulas
  • MBps = IOPS / (1048576/clusterSize) = (IOPS * 16) / clusterSize
  • IOPS = (1048576/clusterSize) * MBps = (MBps * clusterSize) / 16
