Power Consumption and Environmentals
In terms of power consumption, the Barracuda ES.2 SAS drives appear to be pretty strong for a SAS product. We see virtually no power difference between the ES.2 SAS 1 TB drive and other 7,200 RPM class products. As there are no other 7,200 RPM SAS drives on the market, it’s likely that the Barracuda ES.2 SAS is the lowest-power 3.5” SAS drive on the market today.
Along with the low power attributes, we found the drives to be nearly inaudible during our testing. In addition, the drives only got warm to the touch, even after prolonged testing, which means that active cooling will not be necessary for these drives. However, with such high capacity, additional drive cooling is never frowned upon, as you'd never want to take unnecessary risks with so much data in such a small space.
