The present disclosure generally relates to more efficient use of a delta buffer. To utilize the delta buffer, an efficiency can be gained by utilizing absolute delta entries and relative delta entries. The absolute delta entry will include the type of delta entry, the L2P table index, the L2P table offset, and the PBA. The relative delta entry will include the type of delta entry, the L2P table offset, and the PBA offset. The relative delta entry will utilize about half of the storage space of the absolute delta entry. The relative delta entry can be used after an absolute delta entry so long as the relative delta entry is for data stored in the same block as the previous delta entry. If data is stored in a different block, then the delta entry will be an absolute delta entry.
