LattePanda Mu Ultra: x86 Compute Module for Embedded AI · File : lp-mu-nvme-benchmark.sh · Language : bash · Use case : Benchmark des performances du stockage NVMe M.2.

Using fio to measure sequential throughput and random IOPS.

Ensure the NVMe drive is mounted or accessible. The script creates a temporary 1GB file for tests. Results depend on the quality of the installed M.2 NVMe SSD and the module's cooling.
