First things First Why do we tend to use 1MB IO sizes for throughput benchmarking? To achieve the maximum throughput on a storage device, we will usually use a large IO size to maximize the amount of data is transferred per IO request. The idea is to make the ratio of data-transfers to IO requests […]
