I am curious to know what is the normal operating temperature of
consumer SATA drive, and what is the considered maximum limit I need to
watch out?
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,
