Why need to perform hard drive optimization on Windows 10?

When your computer slows down, you might consider optimizing your computer's hard drive, for it has a direct impact on your PC's performance. If the hard drive is not in good condition, it will cause the computer to be unresponsive, and in severe cases, will cause the computer freezes.

Is it beneficial to perform hard drive optimization on Windows 10? Yes! Properly optimizing a hard drive is beneficial when it's performing poorly.

However, you need to be aware that due to the different construction of HDD and SSD, their optimization methods are also different. Defraging HDD will improve its performance, but defraging SSD will seriously damage this SSD.


How to optimize hard drive on Windows 10

How to optimize hard drive on Windows 10? In the following content, we'll talk about some tricks to optimize your hard drive and improve its performance.

▶ Method 1. Defragment hard drive

If your PC hard drive is HDD, its poor performance may be caused by too many file fragments, because the hard drive will spend a lot of time reading the scattered data. So, you can try to defrag HDD to optimize the hard drive with the Defragment and Optimize Drives.

Step 1. Press "Windows", input "defragment and optimize drives" on the taskbar, then press "Enter".

Step 2. In the new popped window, choose the target drive and click "Optimize" to defrag it.

 ▶ Method 2. Turn on the Write Caching

If you purely want to increase the read and write speed of the hard drive, you can enable the Write Caching. Since the computer writes data to the cache faster than to the hard drive, when you enable the Write Caching, the hard drive will be faster. The detailed steps are as follows:

Step 1. Click the "Windows" icon and type "device manager", then press "Enter". In the new window, click "Disk drives".

Step 2. Right-click on the target drive and click "Properties".

Step 3. Select the "Policies" option at the top of the new window, then tick "Enable write caching on the device".

Turn On Write Caching

Note: The data stored in the cache is only temporary, so it can be easily losed when your PC is turned off suddenly.

▶ Method 3. Enable Storage Sense

The hard drive also performs poorly when the space of it is insufficient. Therefore, you need to free up hard drive space on your PC. In addition to the commonly used Disk Cleanup, you can also try Storage Sense on Windows 10 to optimize hard drive.

Step 1. Click "Windows" and "Settings", then click "System".


Step 2. In the new window, click "Storage" and turn on "Storage Sense".

Step 3. If you want to set others, you can click "Configure Storage Sense or run it now" for the detail.
