In the Main section, there is an entry for Self-Test Failure for disks under the SCSI category, but not for SATA or NVMe drives. The "[Backup+ Desk] Self-Test Failure" sensor value only appears in the Sensors section when the disk is listed under the SCSI section (in the case of the ST5000DM000, both the SATA and SCSI sections). Disks that are only listed under SATA, such as a WD6003FZBX in a StarTech enclosure, do not have self-test results in the Main or Sensors sections. It would be ideal if all types of disks should receive automatic self-tests.
Second, if an SSD uses the NVMe interface, there is only a short list of mostly Yes/No attributes, while HDDs and SATA SSDs have the full long list of SMART attributes. It's not that NVMe SSDs don't report these attributes, as some other tools are able to display the comprehensive list of objective SMART attributes regardless of the SSD being NVMe. An example of the SMART attributes provided for an NVMe SSD (HFM512GD3JX016N), which has been confirmed with other tools to report the standard attributes, is:
