For our power consumption testing, we have the drive connected to the system as a secondary drive. To record the wattage, we are now utilizing a Quarch Technology Programmable Power Module. It allows us to accurately measure power consumption over time and is flexible enough to allow us to test any SSD that comes our way.
When enterprise-class storage is deployed, not only one or two drives are set out in a deployment, hundreds to thousands are, therefore, when booting a NAS or SAN it is important to ensure the power sources will be able to provide enough power to the systems. First, we look at idle power consumption and workload averages at a QD of 256. This helps us gauge IOPS per Watt.
Our power analysis may change as time goes on, but for now, we are looking at just a few metrics with the main goal of measuring our results against the manufacturer’s ratings.
Briefly looking at the results above, it is quite apparent that the Intel DC P4510 doesn’t require a ton of power to deliver its very competitive performance profile. Even under the most power-hungry workload, sequential write, the 8TB model consumed just 14.3W! Following behind it, the 3.2TB SN100 consumed an additional 4W. From this alone, we can tell that it is going to deliver some impressive efficiency results. Let’s move on to our next graph to see just how efficient it is.
Overall, the Intel DC P4510 is very efficient, especially the 8TB model. During the sequential and server profiles, the 8TB model delivered the highest efficiency out of our comparison pool and the 2TB model delivered some respectable results as well. It’s amazing to see this kind of performance with such little power needed.
