Just bought a Samsung SSD 850 EVO 250GB. The write speed is supposed to be up to 520 MB/s I have 5727MB/s. The read speed is supposed to be up to 540 MB/s I have 6142MB/s. My randome writa and read is also tens of thousands to much, is this in some way fixable? Or is the performance benchmark from "Samsung Magician" wrong?
