Bonus tips: How to speed up your disk

What is the result of your disk speed test? If it doesn’t reach your expectation, don’t be upset, here, we have some tips for you. You can try some of them to speed up your hard drive.

1. For HDD

▶ Tip 1. Disk defrag

File fragmentation might be the most annoying factor that drags your hard drive speed down. They are split data files separate around on your HDD. Since their location is too decentralized, your HDD will need more time to find them when you try to boot some programs.

Defragment is to reorganize those split files and rearrange them orderly, then your HDD can find all the needed files quickly.

To defrag your HDD, AOMEI Partition Assistant can help you. Right-click the HDD and choose “Disk Defrag”.

◤ Note: You can choose “Schedule” if you’re afraid to forget to defrag your HDD regularly.

▶ Tip 2. Extend C drive

This advice is for users who use an HDD as a system disk. Your OS needs more available space to store OS data and store them to ensure your PC runs smoothly. If there’s unallocated space on your disk, you can merge it into your C drive. But if your disk doesn’t have it, you can directly allocate free space from another drive to your C drive. All data is safe.

2. For SSD

Unlike HDD, SSD can’t be speeded up by defragment. What’s worse, if you defrag your SSD, it will shorten its lifespan.

Step 1. Press “Windows” + “R” and type CMD to open it.

Step 2. Type: “fsutil behavior query DisableDeleteNotify” to check if the Trim feature is on or off.
