OCZ Vector 180 960GB 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 until we get to 100% writes, in 10% increments. We believe this will be the next major area SSD manufactures will address after performance consistency.

 

Sequential Mixed Workload Bandwidth

OCZ's made note of performance tuning for mixed workloads. It appears the company has. The Vector 180 loses less performance in steady state mixed workload tests than any other SATA 1TB drive we've tested. The Extreme PRO does come a very close second.

 

Sequential 80% Read / 20% Write Bandwidth

In this chart, we see the 80% read results, a representation closer to a consumer mix. Two drives really standout for highest performance and Vector 180 is one of them.

 

Random Mixed Workload Response Time

The 50% random read mix performance is down a bit compared to some of the other products. We never could figure out the QD4 dip, but we suspect it has something to do with the random read QD4 dip we saw on the previous page.
