How to Calculate Disk I O
What is Disk I O?
A disk I/O calculator estimates read/write throughput, IOPS (I/O operations per second) requirements, and storage latency for different workload types. SSDs deliver 100,000+ IOPS vs HDDs at 100–200 IOPS; choosing the right storage tier is critical for database and high-throughput workloads.
