Plextor M6e Black Edition 256GB 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

None of the drives on the chart are particularly well suited for mixed workloads. There are several 2.5" SATA drives that outperform the drives on this chart in nearly all except the 100% read and write tests.

 

Sequential 80% Read / 20% Write Bandwidth

Research has led us to focus on the 80% read 20% write metric for consumer use. At that workload, the M6e Black Edition 256GB is the slowest drive on the chart.

 

Random Mixed Workload Response Time

Mixed random data is another metric entirely. Here, the new Plextor M6e Black Edition products perform very well, and are much faster than the previous generation from Plextor, and even Samsung's rocket ship XP941 that uses PCIe 2.0 x4 (four lanes).
