In the documentation Deduplication Building Block Guide (commvault.com), it is mentioned that:
“The DDBs created for Windows Media Agent should be formatted at 32 KB block size to reduce the impact of NTFS fragmentation over a time period.”
Is the format at 32 KB referring to the block size of the disk itself (NTFS block size) or referring to the “Block Level Deduplication Factor” parameter of the Storage Policy as shown below ?

Thanks but practically, we should format the disk where the DDB resides on to 32KB AND also change the block level deduplication factor to 32KB or leave it to 128KB ?
