Como calcular IOPS storage?

O valor do IOPS está associado ao tempo de resposta e carga de trabalho do equipamento físico. É possível aumentar esse índice com a alocação de mais dispositivos, de diferentes propósitos. O cálculo é feito com a fórmula: 1000 dividido por latência rotacional + latência de busca.

How to calculate IOPS or convert Mbps to IOPS?

IOPS = (MBps Throughput / KB per IO) * 1024. Or. MBps = (IOPS * KB per IO) / 1024. So let’s say we have an SSD claiming a Random 4K write speed of 20,000 IOPS and it achieves 76.2MB/s in the CrystalDiskMark with the QD32 write test.

What does it mean to have 4K IOPS?

Usually when a Random 4K IOPS figure is given, it may state that this is at a certain queue depth, such as 4, 16, 32 or 64. With a queue depth of 4, this means that there are 4 separate threads taking place with the drive, each thread independently running its own transfers.

Which is better sustained MB / s or random IOPS?

The second rating is the 4K Random IOPS performance, which gives a much better idea of how the drive will perform in the real world. The sustained MB/s rating is the sequential transfer rate the SSD will maintain continuously, such as over a period of 30 seconds.
