Bigger HDs run hotter?

[Starrx05]

I'm using mobile racks for several PATA IDE drives I have here. One is an old IBM 7200RPM 2MB cache, the other, a Seagate 160GB 7200RPM 8MB cache. Within 5-10 min w/o using, temperature as reported by the mobile rack's LCD is around 35C on the IBM, while the Seagate would show little over 40C. Another PATA 80GB I have also shows around 33-34C too within few mins upon startup. That is w/o me reading or writing to them. So bigger capacity drives generate more heat? If I hook up a PATA and a SATA drives at same capacity outside and touch their tops. The SATA gets hot really quick. Both are running at 7200RPM. So SATA drives generally run hotter than the old PATA ones?

while i have no tests on this, i don't believe there will be drastic ranges in temps across your hdd's in the same environment unless one had a problem. IF ANYTHING, the newer, denser drives will be AT MOST 5C hotter than an old, small SATA or IDE drive

Some of the larger drives may run hotter then smaller drives, but it is not because of their size. Motor efficiency is probably the biggest offender. During my latest tests for throughput, I found this information:

WD 6400AAKS 27c
WD 3200AAKS 34c
WD 1600JS 27c
Seagate 250GB 37c

The Seagate is an older model, and draws .62a, the WD 1600JS is slightly newer and draws a thumping .92a but runs cool, and then there are the two latest WD AAKS series drives that run at 27c and 34c. These were all done under basically the same conditions in my work room.

A drive with more platters would create more heat/noise. The extra weight makes the motor work harder and more platters air drag.
A modern 500GB hdd could have fewer platters and a better motor then an old 80GB and therefore run more cool.
I guess a simple answer to your question is yes though...

I have read a report recently that investigated the statistics of hard drive failure. Hard drives in the 40C range are actually expected to live the longest.



disclaimers: IIRC, YMMV, IDKmyBFFjill.

I am certain that a reasonable temperature is better for a hard drive than a very cold temperature of around 20C.

So theoretically, with Everest Ultimate Edition reporting my WD 640GB @ 38c, I shouldn't be concerned?
