Desktop Test System





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 Read




Sequential Write




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 abnormality, the rest of the sequential charts fall in line with our expectations. With sequential data, we had reads over 700 MB/s, and writes under 340 MB/s.



Random Read




Random Write




Random 80% Read 20% Write




The random performance was also in line with our expectations. The M6e Black Edition 128GB gets really close to 10K random read IOPS at QD1, but doesn't manage to break the plane. The performance scales really well as the load increases. On random writes, the difference between QD4 and QD10 is quite small until we get to 4K and 8K loads.
