    Question Ssd Samsung 860 EVO speed dropped after firmware update.

    There are ssd EVO 860 500Gb , z77p-d3, e3 1240 v2, 16 Gb Atermitter. After updating the firmware from rvt03b6q to rvt04b6q, the write speed decreased (from 520 to 370 Mb/s). Another drive of the same model in this computer works fine (the firmware was not updated on it). How can I fix this?
