Xerxes Nano Carrier Board for Jetson Orin Nano Super and Turing RK1 Modules · File : xerxes-nano-m2-storage-benchmark.sh · Language : Bash · Use case : Tester les performances du stockage M.2 PCIe Gen 3 situé sous le module pour valider le débit.

Disk benchmark script using dd to measure read/write speeds of the Xerxes Nano's M.2 PCIe Gen 3 slot.

Hardware: Xerxes Nano with NVMe M.2 SSD installed under the Jetson module. Format and mount the disk (e.g., sudo mount /dev/nvme0n1 /mnt/nvme0). Execution: ./bench_m2.sh. Results depend on the SSD used but validate the PCIe 3.0 x1/x4 link depending on module configuration. Watch temperature during the test.
