Step 2. Right-click the SSD partition, choose "Advanced" and "Partition Alignment".


Step 3. In the new window, you need to choose partition sector to align. In SSD optimization, we strongly recommend you to use "4096 Sector" (usually we know it as SSD 4K alignment).


Step 4. After that, click on "OK" and "Apply" to commit the operation.


Solution 5: Allocate free space to C drive

One of the main reasons for slow Windows 11 SSD is the low system partition space. So extending the C drive will provide a better environment for OS to run. AOMEI Partition Assistant is featured with various functions to enlarge the size of system drive like moving folders or apps to a different drive, allocating free space from one partition to C drive, etc. Here, we will take "Allocate Free Space" as example.

Step 1. Open AOMEI Partition Assistant, right-click drive D (or other partition with enough space) and select "Allocate Free Space".


Step 2. Set the size you want to move to C drive, then click "OK".
