IOPS and throughput conversion

tags: network

To convert MBps to IOPS (or IOPS to MBps), we need to know about the formula.

IOPS = (MBps Throughput / KB per IO) * 1024
or
MBps = (IOPS * KB per IO) / 1024

!!! In traditional hard disk, when measuring performance for random read/write, look at IOPS. The behaviour of random read/write costs most of time in seek and latency. It is different to sequential read/write behaviour (read or write multiple and continual sectors in a track). So when measuring sequential read/write, we focus on the throughput.
