I am curious to know what is the normal operating temperature of

These are my disks SMART output under FreeNAS 0.7RC2, where my
ambient temperature is 28 C without air conditioning.

As you can see from the above, the Hitachi drives (2 x mirror) are
always hotter than Seagate (4 x raidz), although they are on the same
cooling mechanism.
Thanks in advance,
Dedhi
Those temperatures are fine, I wouldn't worry about it. If you get
much above 45C you might want to get a bit more airflow over the
hitachi drives. It's possible the mirror drives are doing more
seeking thus driving their temps up as well.
