Compare sequential and random I/O performance for storage devices. HDDs: random IOPS limited by seek time (~100 IOPS); SSDs: 10K–1M random IOPS. IOPS = 1 / (seek_time + rotational_latency + transfer_time).
Enter the values for the scenario you are assessing. Compare sequential and random I/O performance for storage devices. HDDs: random IOPS limited by seek time (~100 IOPS); SSDs: 10K–1M random IOPS. IOPS = 1 / (seek_time + rotational_latency + transfer_time). Use the sequential vs random iops result to inform your calculation.
