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 an SSD with advanced features like DEVSLP enabled.

The sequential tests show us that the read performance is over 700 MB/s at reasonable queue depths. The sequential write performance tops 600 MB/s when dealing with larger block sizes.

We don't measure random performance at high queue depths in this section, but we'll look at the hero numbers later in this review. The 512GB M6e Black Edition gets really close to breaking into the 10K random IOPS area at QD1. The performance scales really well on the read chart as the queue depth increases. The write test chart shows very little difference between QD4 and QD10.
