As I recall, they all consume about the same power, so they should
all be about the same temperature if given the same cooling.

Wrong, most obviously with the steaming turd Maxtor external drives.

No they dont. The MAXIMUM specified in the
datasheets are similar, a different matter entirely.

Wrong again when some drives are designed to get more
heat away by conduction to the drive bay stack metal.
Those get stinking hot when run loose on
the desktop with no airflow over the drives.

Not if you run it loose on the desktop it doesnt.

What were your own results for 7200 RPM drives? Except for my 80GB
Seagate with the metal cover over its circuit board, all my drives
measured 42C, +-1C, at the bottom screw holes of the the aluminum
casting, The drives were run for two hours before measurements were
taken for each test (idle first, sequential read later).

That the Seagates got significantly hotter than say the Samsungs.
Some of them got stinking hot in no time, you didnt even need to
measure anything, the drive was stinking hot by touch alone.

Average, too, as I recall.

That's irrelevant, unless that's how you mount your drives.

Nope, not with most of them on that particular power use.

No it isnt, its the evidence that your claim that the power
consumption is all that matters drive temp wise is just plain wrong.

The source of the heat is the power consumed.
Consume the same power, get the same heat. Cool them the same,
and that will result in the same temperature, other than minor
differences in the effectiveness of their heat sinks.

Duh.

Not necessarily. Depends on how the drive is designed
to get rid of that heat. If its designed to get rid of it by
conduction to the drive bay stack, running it loose on the
desktop with no drive bay stack will see that drive heat
up rather more than a drive thats designed to convect the
heat away from the entire top surface of the drive for example.
Ditto with a drive thats designed to get rid of the heat using
a decent airflow over the drive. Run that drive with no airflow
and you will get a different result than you will with a drive
thats designed to convect the heat away off the entire top of
the drive when its loose on the desktop with no airflow over it.
Cool them the same,
That wasnt what was being discussed. What was being
discussed was the result you get with drives with the
same power use in a PARTICULAR cooling regime.
and that will result in the same temperature, other than minor
differences in the effectiveness of their heat sinks.
Mindlessly over simplified, again.

What is "stinking hot" in Celcius?
Dont believe it.
What did you measure?
You should be using the SMART temp.
I used a thermometer that was accurate to better than 0.4C, and not all
my drives reported SMART temp.
Easy to claim.
As easy as claiming that you "didn't even need to measure anything".

The SMART temp.
What was the SMART temp., and how accurate is it for the temperature of
the mechanical portion of the HD? Does the drive's temp. sensor touch
the aluminum casting, or does it just measure chip temp?
You should be using the SMART temp.
There arent that many 7200 RPM drives that dont.
One I tested didn't, so how can I compare it to the others when I don't
know what the SMART temp. sensor measures?
Pathetic, really.
Why didn't you just write "ibid" instead of repeat that?

The temperature of the mechanical portion
of the HD is completely irrelevant.

Who cares ? Its clearly what the manufacturer
has decided is the temperature that matters.

You just leave that one out of the collection, ****wit.

Don't expect sense from Rod. On the rare occasions that he's lucid he's
pretty good but most of the time he's raving.
