![]() This is better tested with brand-new, empty drives. Furthermore, changing the logical sector size requires to delete everything on the SSD and basically reinstall the OS from scratch, which makes it even more unlikely for users to attempt it and see if differences arise. ![]() Some people for instance may think that the logical sector size is the same as the partition's cluster size (which defaults to 4 kB on Windows), but they are unrelated with each other. This is possibly true for fast NVMe SSDs and high-performance (non-Windows) file systems in high-I/O environments, but it is unclear whether Windows performance with ordinary NTFS partitions would be improved, and the subject is sort of obscure and somewhat confusing. Why change this setting? In theory, the 4K native LBA mode would get away with the "translation" the firmware has to do with 512-bytes logical sectors to map them to the underlying 4K "physical" arrangement (if a physical/logical distinction makes sense for SSDs) and may offer somewhat higher performance in this way.
