I want to detect SSD drive and my program must first confirm detected drive is physical HDD or SSD.

I am trying with WMI in C#.

Please let me know if you have any idea.

Thanks in advance,

Neal.

I've had to work on a system that used HDDs and SSDs interchangeably and I can tell you this much... Windows doesn't know the difference! ...so any way you do it, its going to be based on a made up system you or someone else derives and will without a doubt lack consistency across drive manufacturers. Good luck!

Yes, albert you are right at this point that windows doesn't know the difference between. So, I also came on same conclusion and as per WMI classes its returning ItnerfaceType property for disk drives. And I found different types of InterfaceType of SSD drives for different manufactureres.
Please check below link and interfaceType of every SSD drives.

I have also found MediaType but for both still I am not confident so, need more advice from experts.

The best i found in other threads about WMI is looking for the name-model in win32_diskdrive and check if the model has "SSD" anywhere in the name.
Another way is to check the winsat-score of the disk using the win32_winsat-class.

My personal favorite: "Search for code that reports drive rotation speed. SSD should have 0rpm."
