Logged to readnvme.log and the detailed NVMe information is logged to .īy default, only a subset of NVMe parameters are displayed to the console. This command displays NVMe information to the console and logs it to a couple of files. For example, the command below reads NVMe 0. This console command reads the information for an NVMe device. NVMe 0 : Sandisk WDC WDS250G2B0C-00PXH0 250GB On Linux systems the NVMe number is the nvme devices number.įor example, /dev/nvme2 would be listed as NVMe 2. On Window systems the NVMe number is the physical drive number.įor example, physicaldrive2 would be listed as NVMe 2.
