Seagate Barracuda 7200.12 1TB

Overall Score

To test power consumption of these drives we used a clamp meter with 1mA resolution. We tested both the 5v and 12v wires on the SATA power connector at idle and under load. The temps recorded for each drive are the highest temps observed after running HD Tune tests 3 times.

Since our last review, we have put some thought in to power consumption testing and what really matters to people looking to build low-power computers. To address this, we added in a graph that shows GB per watt. To get this data, we assume the drives would operate at idle 80% of the time and peak 20% of the time. In reality they will be operating somewhere between peak and idle, but for the purposes of our testing the 80/20 forumula seemed like an OK starting point.

As you can see, the 1.5TB drive has the best GB per watt ratio. The 7200.12 1TB drive is a strong contender here, beating out the F1. The Velociraptor is the clear loser due to it’s low capacity.

This drive is continuing the trend in the 7200.12 series of having great thermal performance. We like this because to enthusiasts ambient case temps are obviously important.
