Option 1, lists or even manufacturer website spec sheets

There's sites that maintain lists, example: https://www.reddit.com/r/DataHoarder/comments/184vwtd/complete_list_of_smr_drives_as_of_112623/ or https://nascompares.com/answer/list-of-wd-cmr-and-smr-hard-drives-hdd/

Option 2, Use a SMART tool and look for TRIM support

There's more obvious tell-tale signs: SMR drives may support the SATA TRIM command:

Option 3, Some tools can detect SMR drives without relying on databases or TRIM support

There's also less obvious drive parameters that can reveal a drive being SMR even in absence of TRIM support:

I suspect it may be examining the "general purpose log" or look for "Device Managed Zoned Capabilities" support.

Option 2, Use a SMART tool and look for TRIM support

There's more obvious tell-tale signs: SMR drives may support the SATA TRIM command:

It should be interpreted like so: If your spinning drive supports TRIM then it is a SMR drive, however absence of TRIM does not mean by definition it's not an SMR drive.

I suspect it may be looking for existence of "general purpose log 30".
