Performance
Performance has been tested on the latest AMD Ryzen platform. The platform contains the Ryzen 9 3900X processor and ASUS Crosshair VIII Impact motherboard.
All tests were performed on Windows 10 Pro x64 OS with the latest updates.
As usual, we will start with the ATTO Disk Benchmark in the latest version.
I’m not sure if this is a matter of test platform or the card itself, but we are a couple of MB/s shy of the declared maximum speed.
Above, you can see the latest ATTO benchmark, which is usually showing a bit lower than expected results. We were still able to reach up to 95MB/s read, and up to 60MB/s write bandwidth.
A bit higher results are in CrystalDiskMark, where the card was able to reach 99MB/s.
Below are some additional tests which are showing high overall performance but again slightly lower than expected.
PCMark 10 is not the best benchmark for SD and micro SD card tests, but it shows a longer constant load, so we know what to expect if we are working for longer in a mixed load environment.
Results in Anvil’s Storage Utilities are usually lower than producer’s declares, and we are used to that. Regardless of how the benchmark is acting, over 94MB/s is still a good result.
As I mentioned earlier, I’m not sure if our test environment is the problem or simply the card in our tests can’t show it’s maximum potential. As far as read bandwidth was about as high as declared 100MB/s, then our write bandwidth tests were showing about 20MB/s less.
There is clear info that depends on the used device, the performance may vary, and we understand that. Especially write bandwidth highly depends on the test environment.
