Along with the move to a new platform, we decided to make a change in one of the benchmarks. There’s a relatively new benchmark called Anvil Storage Utilities that is in beta but close to production. It’s a very powerful tool that measures performance through a variety of tests which can be customized. Since some of the tests more or less duplicate what we get from other benchmarks we use already, we decided to use the IOPS (Input/Output Operations Per Second) testing on 4kb file sizes at a queue depth of 4, 16, and 32. IOPS performance is something SSD makers tout quite a bit but we generally don’t do a lot of IOPS testing because frankly a lot of users can’t relate to IOPS metrics as well and it tends to be more meaningful to the enterprise/server crowd. Still, it is another performance indicator with relevance and while some drives post good MB/s numbers, their IOPS scores aren’t always commensurate which this test will prove out.
Benchmark Results: The overall Anvil SSD Benchmark score was 5,048.76 with 100% compression (incompressible data) and 5,143.24 with the Applications test setting of 46% compression. 4K QD16 IOPS performance was right around 88,000 IOPS Read and 80,000 Write. Corsair rates the Random 4K Read/Writes at around 100,000 IOPS and 90,000 IPS at a QD of 32, so we are in the ballpark.
