It achieves the specified values of 440 MB/s for me. And so far it has always worked without any problems. I can't say anything about the Samsung, but according to its specifications it should go up to 540 MB/s, so it's quite a bit faster.
In any case, I am very satisfied with the ADATA, especially with the price-performance ratio.
