Most hard drives have a S.M.A.R.T threshold of 55 °C (maximal operating temperature), but it is generally advised to keep temperatures below 40 °C.

Now I have a Seagate SkyHawk 8TB (ST8000VX0022) which gets consistently around 5 °C hotter than my Seagate Desktop 4TB (ST4000DM000). Swapping position in the case doesn't make a difference, so it's not the airflow. But the threshhold for the Skyhawk is also increased to 60 °C while for the Desktop it's the usual 55 °C.

Does it mean anything that Seagate Technology increased the threshhold for the Skyhawk? Does it handle higher temperatures better (around 45 °C) in the sense that a reduced lifetime does not occur?

Because even with the front fan disabled, the Desktop was always under 40 °C. I have to live with the noise if I want to keep the Skyhawk below 40 °C.

There is nothing about SMART particularly relevant to this topic. SMART is just a monitoring system that involves certain communication between your hard drive and the computer.

If a hard drive has a higher acceptable operating temperature, then that means that the hard drive has a higher acceptable operating temperature.

There are other things it can mean too, but that's the basic bit, and everything else stems from it or varies based on other factors.

The answer to your first question is yes.

"Each drive manufacturer defines a set of attributes,[18][19] and sets threshold values beyond which attributes should not pass under normal operation."

https://en.wikipedia.org/wiki/S.M.A.R.T.

The second question could only be answered by Seagate. It's certainly a good sign that they rated this drive higher than a previous drive you've inspected but I am not confident that would translate directly in to higher MTBF. I'm afraid that without a statement from Seagate this is a "matter of opinion" and can't be answered by a forum member who is not a Seagate engineer.
