Retrieving SMART metadata for a drive is done with the information option of smartctl. This prints the device’s identity and capabilities, including the vendor, model, firmware version, serial number, and whether SMART is supported and enabled on that device. That broad snapshot is exactly what you want when you’re looking for SMART device information on a Linux system, and you typically run it with elevated privileges to access the disk, for example: sudo smartctl -i /dev/sdX. Other flags focus on specific aspects—health status, self-test results, or SMART attribute values—rather than the general device information.
