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


The M5M actually performed a bit better on the write end of the scale (right side) than the M6M model in our preconditioned sequential mixed workload test. With the drives conditioned like this, the M6M writes at the slowest rate of the drives that actually finished the test.

Sequential 80% Read / 20% Write Bandwidth

Two drives failed the twelve-hour test. In the 80% read 20% write section, the M6M actually performed a bit better than the M5M and the BP4e. Sandforce controllers dominate this test though. We use 50% entropy (incompressible data), so SandForce doesn't have an advantage from the test; the SF-2281 is just able to perform very well with mixed workloads.

Random Mixed Workload Response Time

In this test, we use 50% reads and 50% writes while testing with random data. The M6M does well here, but the M600 does very well.
