Python package with console commands to list, read, and test NVMe SSD installed in computers running Windows and Linux OS.
Features
- Console commands to:
- List NVMe devices
- Read NVMe information
- Check NVMe health
- Test NVMe features
- python module that can:
- Read NVMe information
- Read and check NVMe information at regular interval (e.g. check SMART attributes every second)
- Check for critical warnings, thermal throttling, excessive wear, etc.
- Run self-test diagnostic
- Create simple test and test suites
Installation
pip install nvmetools
On Linux OS the nvmecmd utility must be granted access to read NVMe devices with the below commands. Run the listnvme console command and it will display the below commands with the actual nvmecmd path. Run these commands to grant nvmecmd access to read NVMe devices.
sudo chmod 777 <path to nvmecmd>
sudo setcap cap_sys_admin,cap_dac_override=ep <path to nvmecmd>
List NVMe devices
This console command lists the NVMe devices with an unique NVMe number that is required by the other console commands.
listnvme
Example console output
Epic! NVMe Tools, version 0.0.7, www.nvmetools.com, Copyright (C) 2022 Joe Jones
On Window systems the NVMe number is the physical drive number.
For example, physicaldrive2 would be listed as NVMe 2.
On Linux systems the NVMe number is the nvme devices number.
For example, /dev/nvme2 would be listed as NVMe 2.
LIST OF NVME DRIVES
NVMe 0 : Sandisk WDC WDS250G2B0C-00PXH0 250GB
NVMe 1 : Samsung SSD 970 EVO Plus 250GB
Read NVMe information
This console command reads the information for an NVMe device. Provide the NVMe number with the --nvme parameter to specify the NVMe to read. For example, the command below reads NVMe 0.
readnvme --nvme 0
This command displays NVMe information to the console and logs it to a couple of files. The console output is logged to readnvme.log and the detailed NVMe information is logged to nvme.info.json.
By default, only a subset of NVMe parameters are displayed to the console. All parameters can be displayed with the -all parameter. The raw hex data from the commands can be displayed with the --hex parameter.
