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 Anvil SSD Benchmark showed that with 100% compression (incompressible data) the Kingston UC 400 scores 4,383.39. The Samsung SSD 850 EVO 500GB drive scored 5,374 points, we got 4,631 points on the OCZ Trion 150 480GB SSD and 4,206 points on the OCZ Trion 100 480GB SSD.
Benchmark Results: With the compression at 46% to help mimic real world applications better the performance the overall score dropped just slightly on the Kingston UV400 480GB drive.
