Bonus tip: How to optimize your disk

After the operation to test disk Windows 11, if you think the speed is slower than before or doesn't satisfy your current needs, and even worse, it affects the overall performance of your computer, in such cases, you may push yourself to upgrade your disk. You can apply disk defrag to speed up your HDD performance or align partition to make SSD faster.

Since SSD covers more users, here we take partition alignment as an example to show you how easy it is. It can also be realized by AOMEI Partition Assistant Professional. Now, follow the guide to have a try:

Step 1: Open and run the software, select the disk and right-click one of its partitions. Choose "Advanced" and then click "Partition Alignment".


Step 2: In the pop-out window, you can set partition alignment to 4K(4096 Sector) and click "OK".


In this step, if you receive a message saying that "The current partition is already optimized thus there is no need to align it again", you can choose another partition to repeat the previous steps.

Step 3: Then you will back to the main console, click "Apply" and "Proceed" to commit the operation. Repeat the same operation to other partitions until all partitions in the disk are optimized.


Other ways in AOMEI software you can use to advance the performance of your computer:
▣ Clone HDD to SSD: If you are running on the hard drive disk now, you can upgrade to SSD or a larger disk to get faster speed.
▣ Migrate OS to SSD: This is an optional choice if you don't want to copy the entire hard drive to another, you can transfer only OS to SSD to speed up your Windows.
▣ Free up space: Enough disk space will give the system a great environment to run. AOMEI Partition Assistant can help you move folders to a different drive, delete large files or clean up junk files at a regular time.
