    Howto set cache mode to Write through for single drive?

    RamonSmits


      I cannot set the cache mode to Write Through for my single desk drive

       

      I have a 3 disk system:

       

      1x  Samsung 850 Pro M2.SSD 512GB
      2x  Western Digital Red 3TB

       

      I created two drives

       

      1. Containing only the Samsung 850 Pro, no RAID

      2. Containing both WD's in RAID1

       

      Intel Rapid Storage lists all of them in the Storage System View

       

      The top is the WD RAID1 set and I can click both the set and the individual disks on port 0 and 1

      The 2nd is the Samsung 850 Pro on port 7

       

      I can change the Cache mode for my RAID 1 set but not for my SSD drive as shown below.

       

      How do I change the Cache more for my single drive SSD?

            Hi RamonSmits,
             
            PCIe SSD needs to be part of a RAID array; otherwise, it is not possible to use Smart Response Technology.

              Mike,

               

              That is not what I want. I do not want to use my SSD as a cache for my RAID 1 HDD.

               

              I just want to enable Write Through caching on my SSD drive.

               

              Regards,

              Ramon

                Hi RamonSmits,
                 
                I misunderstand your question. You want to enable the option Write Through; however, the option is available only for RAID volumes, for standard drives is not an option.

                  Hi Mike,

                   

                  In what cache mode is the disk now set? I have enable write caching enabled in the windows setting for my disk but I still get the impression that write caching isn't active.

                   

                   

                  Regards,

                  Ramon

                    Hi RamonSmits,
                     
                    Well, our Intel RST application only allows the write cache option to RAID volumes, on single drives the feature is not supported.
                     
                    I found this third party article, maybe it could help you.

                      The Windows settings were already fine:

                       

                       

                      Still, the drive is slow.

                       

                      It seems the issues is caused by Intel RST that just doesn't support this configuration which is pretty annoying.

                       

                      Now I have to:

                       

                      - Move all data from my "Western Digital Red 3TB RAID1" disk to my NAS

                      - Disable Intel RST in the BIOS and switch to AHCI

                      - Reinstall Windows 10 on my Samsung 950 Pro

                      - Create a new software RAID 1 via the Windows 10 Disk Manager

                      - Move all data back from my NAS to the software RAID1

                       

                       

                      Thanks Intel! :-(

                        Once again we apologize for all the inconvenience.
