Explanation
IOPS (Input/Output Operations Per Second) directly measures how many read/write operations a disk can handle per second, making it the standard metric for evaluating disk throughput and performance under database workloads - exactly what a server administrator needs.
- RPM (Revolutions Per Minute) describes how fast a hard drive's spindle spins - a hardware characteristic, not a throughput measurement.
- Latency measures delay (how long a single operation takes), not volume of throughput; it's a performance metric but not throughput.
- Reads is too vague - it's not a defined, measurable metric in standard server monitoring contexts.
Memory tip: Think of IOPS like "transactions per second" at a cash register - the more operations per second the disk can handle, the higher its throughput. Database servers live or die by IOPS.
