`m2-storage-benchmark.sh`

Raspberry Pi Smart Display Module · File : m2-storage-benchmark.sh · Language : Bash · Use case : Benchmark de performance du stockage NVMe ajouté via le port M.2 du module.

Bash script to mount an M.2 NVMe storage and run a performance benchmark with fio.

Insert an M.2 NVMe drive into the dedicated slot on the Smart Display Module. Ensure the NVMe driver is loaded. The script mounts the drive and runs fio to measure IOPS and latency. Ideal for testing AI accelerators or fast storage.
