Disk I/O Performance Benchmark

Simulate heavy disk write/read operations to stress the storage subsystem.

1. Execute Disk Stress (75%)

Trigger disk stressors to target approximately 75% I/O utilization for a duration of 120 seconds:

sudo stress-ng --hdd 1 --hdd-bytes 1G --timeout 120s

stress-ng disk

tip

Increasing the number of --hdd workers or adjusting the --hdd-write-size can help reach the desired 75% utilization mark depending on the underlying disk performance (SSD/HDD).
