Examples include the following: 4 KB sector alignment with hard disk drives supporting Advanced Format (AF) Track partition alignment, partitions starting on track boundaries on hard disk drives.
What does SSD alignment mean?
SSD alignment mostly refers to SSD partition 4K alignment because SSD adopt the smallest 4K sector in file system to save data. If the smallest 4K allocation units are not always aligned with the 4K pages in SSD, the performance of SSD could be affected.

What is a sector by sector clone?
Sector-by-sector clone, also known as bit-by-bit copy, means to clone all the sectors on a hard drive, even if the sector is blank or it is a logically bad sector. Thus, the cloned drive will keep exactly the same as the source drive.
