About Western Digital Alignment
Before figuring out what Western Digital partition alignment is and how to implement it, we need to understand some basic concepts about hard drives.
Modern hard drives come in two sector sizes: physical sector size and logical sector size. Physical sector size is the size that the disk can actually read and write, while logical sector size is the size that you can ask it to read and write. To use a hard disk to store data, we need to initialize, partition, and format the hard disk first.
The hard disk is divided into partitions based on logical sectors, and each partition can start and end on any logical sector. If the partition start position is not aligned with the edge of a physical sector, all clusters in the partition will not be aligned with the edge of any physical sector after formatting.
Therefore, when the disk reads the internal data, it will have to access multiple physical sectors. As a result, the read and write performance of the disk will be significantly reduced, and the SSD will run slowly.
So, aligning the hard disk is so important. To align your Western Digital hard drive, you can refer to the following part.
