Align All Partitions allows you to align all partitions on a disk with one click. It can speed up Solid State Drive's (SSD) read and write speeds. Especially when SSD was used as system drive, it could help you improve the overall performance of system.

Before you do

If there are other applications running on the partition which you are going to perform, AOMEI Partition Assistant will notice you to close those applications or to execute this operation in Restart Mode. Therefore, if you are going to align this partition, you have to close these applications or you have to go into Restart Mode to operate it.

This operation may change the original location of your data, to keep the safety of your data, we suggest you view the tutorial "How to Safely Partition" before you attempt aligning partition.

To align all partitions

Step 1. Select a disk you want to align, click the "Align All Partitions" option in the left sidebar to invoke the operation dialog. Or, right click the disk and choose the "Align All Partitions" option in Context Menu.

Step 2. Set partition alignment to the default sector or other sectors (2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096) in the drop-down menu (Default "Optimized" is aligned to 2048 sector), then click "OK".

Step 3. By clicking "OK" this will add a pending operation, and the changes will be represented in the main window. Click "Apply" button on the toolbar to commit the operation.

Apply Alignment


1. When you perform partition alignment, the program will automatically detect whether the partition has aligned. If it prompts you "the current partition is already optimized", at that rate you do not need to align it again.

2. When performing resize/move partition, the program will perform 4K alignment for the partition by default.
