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

One area where most value SSDs have problems with performance is with mixed workloads. Although faster than a hard drive, many value based SSDs slow significantly while multitasking with heavy IO workloads. This is actually an area that SandForce spent a lot of time optimizing, but where the SM2246EN does poorly.

 

Sequential 80% Read / 20% Write Bandwidth

The general consensus is that 80% read to 20% write is the optimal measuring point for consumer workloads. Here we see the 80/20 mix for each of the drives on the chart.

 

Random Mixed Workload Response Time

On this chart, we see the random mixed IO workload. This chart shows a 50/50 read write mix. In this test, the Angelbird SSD wrk actually does very well, as do the other SM2246EN controlled drives.
