Angelbird SSD wrk 256GB SSD Review – Silicon Motion SM2246EN

SSD Power Consumption Testing

Having low power consumption is important to many enthusiasts and the Intel Pro 2500 Series is aimed at business-class customers that are more than likely concerned about the power draw of the systems running under their management. We measure the power at idle and load power states using both sequential and random read/write test data. We’ll be comparing the Intel SSD Pro 2500 240GB to the OCZ Vertex 3 240GB SSD on our desktop system to see how the SandForce SF-2281 firmware has improved over the years and to see if we could notice a difference with DevSleep as that was not a feature that was enabled in the original SF-2281 design and just recently added with the B2 and newer revisions of that SSD controller/processor.

When it comes to an idle power state we found that the Angelbird SSD wrk 256GB drive used 0.27 Watts of power and idle and peaked at 3.23 Watts. These aren’t bad power numbers by any means and the read power consumption numbers were very low. If you have an SSD from several years ago you’ll likely see a nice power reduction at idle. For example the OCZ Vertex 3 240GB SSD from 2011 used 0.50 Watts ad idle which is about a 85% more power at idle. At peak load most of the 240/256 GB drives in the chart above topped out at close to 5 Watts, so to see just 3.23 Watts on the Angelbird SSD wrk 256GB SSD was nice to see. At the end of the day the Angelbird SSD wrk 256GB drive was found to consume the least power of the seven tested drives in four of the five test scenarios.
