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 Kingston DCP1000’s monstrous performance is evenly matched with a monstrous hunger for power. This is especially visible when looking at it’s written power consumption, which averaged just over 40W during testing! Most other results, however, are similar to that of the 2.4TB Micron 9100 MAX, except for when testing with smaller file sizes. Let’s move on to our next graph to see how this translates to efficiency when comparing IOPS per Watt.
Overall, the Kingston DCP1000 isn’t too far off from the rest of our test pool. During random read and sequential read and write workloads it proves to be very efficient. During random write workloads, it looks to be just average in the comparison.
