Compare IOPS per drive type. HDD 7200 RPM: ~100 random IOPS; SAS 15K RPM: ~200 IOPS; SATA SSD: ~90,000 IOPS; NVMe SSD: up to 1,000,000 IOPS.
Enter the values for the scenario you are assessing. Compare IOPS per drive type. HDD 7200 RPM: ~100 random IOPS; SAS 15K RPM: ~200 IOPS; SATA SSD: ~90,000 IOPS; NVMe SSD: up to 1,000,000 IOPS. Use the iops per drive (hdd vs ssd) result to inform your calculation.
