LattePanda Sigma 2: Intel Core Ultra X7 358H Single-Board Server · File : nvme-benchmark-fio.sh · Language : Bash · Use case : Mesurer les performances de lecture/écriture du SSD NVMe préinstallé de 1 To.

Bash script using fio to evaluate bandwidth and latency of the NVMe storage.

Ensure the 'fio' package is installed. This script creates a temporary 1 GB file to bypass the OS cache. It launches sequential read and write tests with high queue depth to saturate the PCIe 4.0 bus. Results display throughput in MB/s and latency in microseconds.
