    Terrible write speed, blazing read speed on RAID1 SSD RST

    OvalPiston

      I have an i7-4770K with 32GB RAM on Gigabyte GA-Z87X-UD5H motherboard.

       

      The OS is Windows Server 2016 running RST 15.8.1.1007. I have two Samsung 850 Pro SSDs in RAID1 setup and initialized.

       

      It is very slow to boot and copy files.

       

      Settings in RST:

      Write-cache buffer flushing: Enabled

      Cache mode: Off

      Link Power Management: Disabled

       

      Running MTI's Read-Write test benchmark, I get an anemic 25MB/s writes, but 900MB/s reads.

       

      What can I do and/or check?.
