BIOSTAR EdgeComp MS-U320: Fanless Intel Wildcat Lake Industrial Mini PC · File : linux-nvme-benchmark.sh · Language : bash · Use case : Tester les performances du SSD NVMe M.2 PCIe Gen4 x2 intégré.

Measures sequential and random read/write performance of the NVMe storage.

Uses the standard 'fio' tool. Ensure the SSD is not mounted for writing during the test to avoid corruption. The path /dev/nvme0n1 is typical for the first NVMe disk. Results depend on operating temperature (thermal throttling possible at full load).

# Installer fio si nécessaire
