Determine type of disk on Windows with Python-CodePudding

I want to list all of my disk and can be able to know its type: "SATA" "NVME" "M.2" or "PCI" on Windows computer.

I made some research with wmi and I get the interface (SCSI or IDE):

c = wmi.WMI()
for disk in c.Win32_DiskDrive():
    print(disk.InterfaceType)

But I don't get the type of the disk. Maybe with the interface I can get the type of my disk ?

Do you have any idea ?

Thx

Query the MSFT_PhysicalDisk class if you insist upon wmi:

import wmi
ws = wmi.WMI(namespace='root/Microsoft/Windows/Storage')
for d in ws.MSFT_PhysicalDisk():
    print(d.BusType, d.MediaType, d.Model)

This should get you what you are looking for

import subprocess

result = subprocess.run(['powershell.exe', 'Get-PhysicalDisk | ft -AutoSize DeviceId,Model,MediaType,BusType,Size'], 
    stdout=subprocess.PIPE, stderr=subprocess.PIPE, 
    universal_newlines=True)

print(result.stdout)
