          Hello Dhaa.
           
          Thank you for contacting Intel Technical Support.
           
          In order to further assist you with your inquiry we will like to know the following information:

          • Why do you want to activate (have access) or modify the “host protected area (HPA)” in your Intel® SSDs?
          • Why do you need the page size and the block erase size of those SSDs?
          Please, take into consideration that our drives already come configured from the factory with a 7 to 10% of over-provisioning space, according to capacity and model. So further over provisioning is not actually required. Over-provisioning sets a percentage of the usable space on a hard drive to be locked away in the Host Protected Area (HPA) of the drive's firmware, ensuring that the disk never hits 100% capacity utilization, for performance and endurance reasons.
           
          We will be looking forward to your reply.

          Best regards,

            Hello Josh,

             

            I didn't know about the 7-10% of over provisioning space of the drives. So there is no further reason to change the hpa.

             

            I want to setup two DC S3510 ssd in a raid 1 array. Raid 1 does not benefit from filesystem options stride and stripe-width.

            But in Magic soup: ext4 with SSD, stripes and strides. | The Last Monkey   I have read it would be useful to set filesystem parameters stride and strip-width according to Page size and Erasure Block like:

            stride = Page size / Filesystem block
            stripe-width = Erase Block / Filesystem block

             

            Best regards,

            Dirk
