    Hi all,


    I bought a XPS15 9550 from dell equipped with 1tb seagate hdd.


    I upgraded main hdd as samsung 960 evo and using 1tb seagate as a secondary storage drive.


    I downloaded samsung firmware, drive, and magician for 960 evo in a RAID mode and switched to AHCI mode


    recently. Now i am getting super slow writing speed as well as an error in support assist.

    can anybody help me figuring out whats wrong and how to fix this??

    Were the write speeds ever good? Did you do a fresh install ever? Are you running the Samsung NVMe driver?
