Technology within a mapped RAID (Redundant Array of Independent Disks) data storage system for avoiding wasted capacity in a hybrid array of data storage drives. Drives from a set of new drives may be added to an original partnership group of drives such that the number of highest capacity drives in the original partnership group remains or is made to be at least as large as a minimum number of drives required to provide RAID data protection. Drives may also be added to the original partnership group such that the number of highest capacity drives in a newly created partnership group is also at least as large as the minimum number of drives required to provide RAID data protection. The minimum required number of drives may be equal to or greater than the total number of drive extents indicated by each RAID extent in a RAID mapping table.
