Nowadays, SSD enjoys fast read-write speed and has better performance than HDD. However, if SSD is not aligned, its read-writ speed will be affected. Well, how to align SSD partition? Is there a freeware to align SSD? This article will show you how to align SSD partition with a professional partition manger.
Nowadays, many people install their Windows Operating system on an SSD instead of a traditional hard disk to improve their computer performance. In theory, the computer whose system disk is SSD will enjoy amazingly fast boot speed as well as read-write speed (especially writing speed), but in fact many users can not experience these advantages. If you've migrated OS from an HDD to an SSD, the partitions may not be properly aligned, which could result in slower performance.
Then you may need to do SSD alignment to solve this issue.
One user described the same situation on the internet: it costs more than 30 seconds to boot his SSD laptop, but some other SSD computers enjoy 12 seconds boot speed.
Here, we give the most probable reason: SSD is not 4K aligned. How does this happen? Now let's read the following contents to learn related knowledge about 4K alignment as well as the reason for SSD not aligned.
What Is 4K Alignment?
As for an HDD with limited size, the size of the default sector is 512 Bytes. However, with the development of capacity of HDD and in order to improve the HDD performance, the 512 Bytes has change to 4096 Bytes per sector which is also called "4K sector".
To ensure the reading and writing speed of the hard disk, cluster need to be corresponded with sector (align physical disk partition with computer logical partition). If 4K sector is not aligned, even for the small amount of data, it will occupy two 4K sectors which cause cross-sector read and write, decreasing the speed of read and write.
When you migrate your Windows OS from a mechanical hard drive to a solid state drive, your partitions may not be correctly aligned. This will lead to an improper performance of your solid state drive, slowing down your computer performance.
