Android Sandisk Extreme 128 GB microSD card benchmark result not as advertised

I got a new Sandisk Extreme 128 GB microSD card and did a benchmark using CPDT app. The numbers are way less than advertised (Up to 160MB/s read and 90MB/s write speeds).
So wondering if I am missing something?

The mobile used is Mi A2 Lite (Andriod One, version 9)
Android gives two options to use the microSD card - portable vs internal - I have selected the later.
