I have used of hdparm -n and smartctl -A but it always seem to be a "per drive" technique as a drive may answer for only one of these tools.

So, is there a standard way to get the drive temperature on Linux (HDD or SSD)? If not, what (other) tools can I use to get this information?

I like hddtemp, which provides a pretty standard way of getting the temperature for supported devices. It requires SMART support though.

Example Usage: sudo hddtemp /dev/sd[abcdefghi]

Example Response:

/dev/sda: WDC WD6401AALS-00J7B0: 31°C
/dev/sdb: WDC WD7501AALS-00J7B0: 30°C

    A shorter way would be hddtemp /dev/sd?. – Rovanion Jun 28 '16 at 22:39

    /dev/sd? spares even more fingers. – kkm Jan 2 '18 at 22:35

    Don't forget the type prefix (PATA/SATA/SCSI) for some devices; this 8-bay UASP tower needs the SATA prefix or else I don't get any temperatures: sudo hddtemp SATA:/dev/sd{a..h} – genpfault May 17 '19 at 2:58

All SMART-capable devices should respond to smartctl. And I guss that only smart-devices have a temperature reading.

All other tools will propably be more or less vendor-specific (like Dell`s omsa). IPMI might be another generic approach, but I doubt, that a temperature-reading of a storage-device is standard there.

As mentioned by Rovanion, to list all drives in one go:

hddtemp /dev/sd?

Or, if you prefer a for loop:

for i in /dev/sd[a-z]; do hddtemp "$i"; done

You might want to try watch "sensors && sudo hddtemp /dev/sd?" which provides cpu and other temperature information in addition.
