Power and environmental requirements may differ.


I installed a Seagate Barracuda ES.2 SATA ST31000340NS 1tB
maximum operating temperature: 55C
watts (average): typical 12.5 Operating: 8.0
from:
www.seagate.com/docs/pdf/datasheet/disc/ds_barracuda_es_2.pdf
replacing a Seagate Barracuda 7200.10 ST3500630A ATA/100 500-gB
maximum operating temperature: 60C
watts (average): seek 12.6 Operating 13.0 Idle 9.3
(7200.10 SATA units have the same power numbers)
from:
www.seagate.com/docs/pdf/datasheet/disc/ds_barracuda_7200_10.pdf

For comparison:
Seagate Barracuda 7200.11 ST31000340AS 1 tB
maximum operating temperature: 60C
watts (average): Seek: 11.6 Operating: 12.0 Idle: 8.0

The ES.2 is spected for more power than the 7200.11.

Note that the allowed operating temperature is higher for the
7200.10 and 7200.11 than the ES.2.

Note also that the 8.0 watts operating seems in conflict with
the 12.5 watts typical. Maybe "Operating" means "Idle"

In my setup the ES.2 ran hotter than the 7200.10, so I had to
install a fan. (The ES.2 drive has a SATA-to-PATA converter
connected to it. This may be what makes the ES.2 drive run hotter,
but the converter doesn't seem to be located near the hotspots.)
