Lenovo T440 - Notebook Power Testing with DEVSLP and Windows 8.1 Pro

 

 

Nearly all of the performance tests run on the desktop system, but we use a Lenovo T440 to run the power tests. The T440 is the latest addition to our client SSD test lab, and allows us to test the notebook battery life offered by a SSD with advanced features like DEVSLP enabled.

Our new replacement for ATTO shows us 4-corner performance, and some mixed workload results as well. We run the test long enough, and in a particular order to get a reasonable level of consumer preconditioning on the drive. In the tests, we show QD1 (green), QD4 (yellow), and QD10 (red).
