I'm using Zabbix Agent 2 7.0 LTS to monitor the SMART attributes of a server that uses SATA, SAS (using an HBA, not a RAID card), and NVME disks:

 
/dev/sda -d sat # /dev/sda [SAT], ATA device
/dev/sdb -d sat # /dev/sdb [SAT], ATA device
/dev/sdc -d scsi # /dev/sdc, SCSI device
/dev/sdd -d scsi # /dev/sdd, SCSI device
/dev/sde -d scsi # /dev/sde, SCSI device
/dev/sdf -d scsi # /dev/sdf, SCSI device
/dev/sdg -d scsi # /dev/sdg, SCSI device
/dev/sdh -d scsi # /dev/sdh, SCSI device
/dev/sdi -d scsi # /dev/sdi, SCSI device
/dev/sdj -d scsi # /dev/sdj, SCSI device
/dev/nvme0 -d nvme # /dev/nvme0, NVMe device
/dev/nvme1 -d nvme # /dev/nvme1, NVMe deviceThe SMART plugin on SAS drive reports only a few attribute (temperature, power on time, serial), for example:

​As you can see the model_name, firmware_version are not parsed correctly.
Using smartctl you can extract much more information for example: scsi_grown_defect_list, scsi_vendor, scsi_product.
This is the output of smartctl on a SAS drive:
