Samsung Phoenix S4LR020 controller ID'd as "Samsung NVMe PCIe SSD Controller"


New Member
My system has three (3) "Samsung SSD 970 EVO Plus 500GB" SSDs.

AIDA64 Extreme v6.33.5700 reports their controllers as "Samsung Phoenix S4LR020".

However, HWiNFO64 7.10-4540 reports them more generically as "Samsung NVMe PCIe SSD Controller".

Attached logs shortened and redacted.

This is because Samsung doesn't use unique PCI IDs for its controllers, so it's not possible to detect the exact model.
What AIDA64 does is it's displays the controller name derived from drive model matched against a drive database. In the PCI device/controller list it's also shown with a generic name.
