Plextor M6e Black Edition 512GB PCIe SSD Review

Sequential Mixed Read / Write Workloads


In this series of tests, we measure mixed workload performance. We start with 100% read, and then add data writes to the mix in 10% increments until we get to 100% writes. We believe this will be the next major area SSD manufacturers will address, after performance consistency.


Sequential Mixed Workload Bandwidth




To be fair, none of the PCIe based SSDs on the chart today do very well in our mixed workload test with the drives in steady state. The M6e Black Edition 512GB does a little better in some places when compared to the original M6e, but a little worse in others.


Sequential 80% Read / 20% Write Bandwidth




The 80% read / 20% write test is important because it's the same mix of reads and writes that most computer users run on a daily basis.


Random Mixed Workload Response Time




Using mixed read and write workloads with random data fares a bit better on the Black Edition. The new firmware performs much better than the original firmware on the M6e, and also allows the drive to perform better than the XP941 products.
