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.
Initial Performance Evaluation - 4-Corner and, then Some Tests
Sequential 80% Read 20% Write
Random 80% Read 20% Write
Our new replacement for ATTO shows us four-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).
Normally, we don't comment too much here, but seeing queue depth one outperform queue depths four and ten at times means that we have to chime in. The lack of a DRAM buffer seems to really hurt performance when working with sequential data and piling on load through native command queueing. This may cause some problems in a few of the tests later in this review, and have a serious impact on your real-world performance at home.
