IOMeter Mixed Performance

Our mixed performance test is conducted in the same manner as our sequential tests, but once the drive is conditioned we run our test profile to look at performance in various read/write states. We start the test with 100% reads and then add write data into the mix in 10% increments until we end up with no reads at all in the workload.

seq mixed performance

The OCZ Trion 100 480GB drive starts out great in our 128KB sequential mixed workload test with 100% reads, but the performance drops off as writes are added and performance never comes back like we expected it to. The new OCZ Trion 150 480GB drive starts out well and then the performance drops off and comes back by the time the drive is doing full writes again! We finally have soemthing close to the traditional bathtub curve that we’d generally expect to see! The OCZ Trion 150 performed better than the OCZ Trion 100 in every mixed workload scenario although they were close in the popular 80/20 read/write workload test.


When looking at 4KB Random mixed workload performance again found that performance tapers off as the number of writes increases, but we did see performance increase with 100% writes. The Samsung SSD 850 EVO 500GB drive was significantly faster in 4KB mixed workload performance tests.

Let’s take a look at temperatures!
