MyDigitalSSD SBX 512GB NVMe SSD Review


Anvil Storage Utilities

Anvil Storage Utilities 1.1.0

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 1, 4, 8, 16, 32, 64 and 128. 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.

Anvil SSD Benchmark with 100% Compression (incompressible data):

Benchmark Results: The Anvil SSD Benchmark showed that with 100% compression (incompressible data) the MyDigitalSSD 512GB drive had an overall score of 7,384.25 points. The drive topped out at 1,380 MB/s read and 923 MB/s write speeds on the sequential performance test with 4MB file sizes.

Anvil SSD Applications Benchmark at 46% Compression:

Benchmark Results: With the compression at 46% to help mimic real world applications better we found the overall score was about as close as you can get to being the same at 7,384 points.

Benchmark Results: When it comes to Random 4K Read performance at various queue depths we see the MyDigitalSSD SBX 512GB drive does okay, but lags behind most of the other NVMe drives.

Benchmark Results: We’ve tested a number of drives with the Phison E8 controller and know that it has less than stellar 4K Random Write performance, so the results here aren’t shocking at all. The Patriot Scorch and MyDigitalSSD SBX both use the Phison E8 controller and the performance lines basically overlap one another. The QD1 and QD2 performance is decent, but moving up to QD3 the performance barely improves and the Phison E8 controlled drives lag behind most of the other drives until QD32.

We’ve tested three drive series with the Phison E8 controller from three difference brands and they all happen to be different capacities. Despite the differing capacities the performance characteristics are exactly the same.
