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.
Mixed Workload Bandwidth
Our mixed workload test shows the Radeon R7 with a heavy bathtub curve as writes are added to the reads.
80% Read / 20% Write Bandwidth
Using a mix of 80% reads and 20% writes to simulate a typical consumer workload, the Radeon R7 does well when compared to the lower priced products on the market, but still lags behind the LSI SandForce architecture found on the Intel Pro 2500.
Mixed Workload Response Time
Here is a look at the response time associated with each sequential test. These tests are important since none of us strictly read or write.
