One of the SSD have to be replace because it is complaining “</SPAN>SSD is approaching the maximum usage limit for writes (wear out) and should be replaced immediately”. I have a 200Gb SSD that will replace the old 120Gb SSD. I want to ask if the write endurance will increase on the 200Gb HDD considering that it will use only 120Gb of the capacity.</P> Fri, 21 Feb 2020 15:16:35 GMT https://community.hpe.com/t5/proliant-servers-ml-dl-sl/write-endurance-on-raid-1-with-two-different-size-ssd/m-p/7080006#M169742 radukong 2020-02-21T15:16:35Z https://community.hpe.com/t5/proliant-servers-ml-dl-sl/write-endurance-on-raid-1-with-two-different-size-ssd/m-p/7080012#M169744 IMHO in theory yes, because it always has plenty of free space.
