SSD Alignment

The traditional rotating disks are divided into physical sectors. The Windows operating systems and their components operate according to this sector logic. Despite the fact that SSDs store the data in a completely different way, they are still being treated with this sector logic.

The alignment of the SSD is required to assure that a logical sector starts exactly at the beginning of a physical page of the SSD. Without the alignment, the sector boundaries and the page boundaries will not match and sectors will span pages. That would require for a Windows write operation to clear two blocks in lieu of only one thus reducing the write speed by 50%.
