ADATA Spectrix S40G 512GB NVMe M.2 SSD review - SSD Performance Atto Disk Benchmark

Atto Disk Benchmark

One of the finest tools available to measure storage performance is ATTO. I love it to death as it is so reliable and produces such accurate results. The great thing about ATTO is that we can test with predefined block sizes. So we can test with a 32 MB sequence of 4 KB files, yet also 32 MB in 1 MB files. This gives us an excellent scope of overall performance with small and large files.

As you can see, writes caved in big time with ATTO.  In fact, we've have seen quite a number of anomalies with the new Realtek controller. more on that in the conclusion though.
