Why extend SSD partition?

SSD, composed of an array of solid-state electronic memory chips, is a storage device. However, SSD cannot be used directly, it needs to be allocated with partition before use. When the computer is used for a long time, the system may prompt the user that the disk space is insufficient. At this time, if you do not expand the SSD partition in time, the computer freeze will affect the user experience, especially for users whose work relies on computers, such as game testers, editors, and designers. To solve this problem, you need to extend the SSD partition on Windows 10.

How to extend SSD partition Windows 10 without deleting partition? 

There are many ways to extend SSD partition in Windows 10. You can use Windows built-in tool Disk Management to merge the required extended partition and unallocated space. But please note that this can only be adjacent unallocated space. If it is non-adjacent unallocated space, Extend Volume will be grayed out.

In this case, you can only seek help from third-party tool. AOMEI Partition Assistant Standard is a professional disk management software, and it is completely free. Its Merge Partition function can help you merge partitions with non-adjacent unallocated space, which makes up for the limitations of Disk Management.
