This section shows your server’s disk I/O activity:
- Read: How much data the system reads from disk (e.g., loading apps, reading files).
- Write: How much data the system writes to disk (e.g., saving files, logs, databases).
Values are typically shown as MB/s or IOPS.
Sustained high writes may indicate heavy logging or database load, while high reads often relate to reporting, cache misses, or data-heavy workloads.
