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
The sequential read test shows QD1 faring better than QD4 and QD10 thanks to the drive's aggressive wear leveling and garbage collection schemes. Aside from that anomaly, the rest of the sequential charts fall in line with our expectations. With sequential data, we had reads over 700 MB/s, and writes just under 600 MB/s.
Random 80% Read 20% Write
The random performance was also in line with what we expected to see. The M6e Black Edition 256GB came really close to 10K random read IOPS at QD1, but didn't manage to break the line. The performance scaled really well as the load was increased. On random writes, the difference between QD4 and QD10 was quite small until we got to 4K and 8K loads.
