Plextor M6 Pro 256GB 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




After introducing this mixed workload test, we've heard that some SSD markets are tuning SSDs to perform better in mixed workload conditions. The M6 Pro 256GB has massive performance loss when just a small amount of data writes are added to the mix.


Sequential 80% Read / 20% Write Bandwidth




The 80% read with 20% write test represents a typical consumer mix. This test preconditions the drives so we're just looking at steady state performance.


Random Mixed Workload Response Time




The random mixed IO test is of interest because your computer is always reading and writing little bits of data. Everything is logged in modern Windows, and each update is a small write to the disk. The trend of this review really seems to come out in this test; the M6 Pro 256GB performs really well, but just can't catch the very best on the market.
