If you know the specific issue affecting your SSD write speed, you can skip to that fix and see how to proceed. If not, try going through each individually to see if it works.
Fix 1. 4K Align the Slow SSD
4K Aligning your SSD can improve its performance by reducing fragmentation, which can slow it down. This can be done using Qiling Disk Master, which has a feature to speed up your SSD by aligning it to 4K.
Here is how to:
Step 1. Go to "Disk management" and choose "Move/resize".
Step 2. Select the disk you want to align and click the "Proceed" button.
To efficiently fix your slow SSD, try Qiling Disk Master now, which can not only fix the issue but also improve SSD read and write speed.
Fix 2. Make Sure the TRIM Command Is Running
If the TRIM command is not running, your SSD may have slow write speeds. To resolve this, you can run the TRIM command on your system. This can be done by enabling TRIM in the BIOS settings or by running a TRIM command in the command prompt.
Step 1. Open the "Command Prompt" as an administrator.
Step 2. To check if TRIM is enabled on your Windows system, open the Command Prompt and type "fsutil behavior query DisableDeleteNotify" and press Enter. A result of 0 indicates that TRIM is running, while a result of 1 means it is disabled.
Step 3. If the result is "1", type the command "fsutil behavior set DisableDeleteNotify 0" and press Enter.
You have successfully enabled the TRIM command on your device.
Fix 3. Enable AHCI Mode
AHCI enables SSDs to operate faster than IDE mode, making it necessary to enable it for optimal SSD write speeds.
Here's how you can do it using the Command Prompt:
Step 1. Run "Command Prompt" as an administrator.
Step 2. Type "bcdedit /set {current} safeboot minimal" and press "Enter."
Step 3. In BIOS, enable the "AHCI" mode.
Step 4. Save the changes you have made and exit the BIOS.
Step 5. To delete the safeboot value from the current operating system, enter the command "bcdedit /deletevalue {current} safeboot" in the Command Prompt terminal while in safe mode.
Step 6. Restart your system for automatic AHCI installation.

Fix 4. Disable Onboard VGA
If your SSD write speed is slow, it may be due to your onboard VGA being enabled. To resolve this issue, follow these instructions.
Step 1. Open the "BIOS" on your computer after restarting it.
Step 2. Go to the "Advance BIOS" section and search for "Onboard VGA" to access and configure the settings for the onboard graphics card.
Step 3. Choose "Disable."
Fix 5. Choose a High-Performance Mode
If your SSD isn't getting sufficient power, it may not work properly. To ensure it runs at its best capacity, choose a high-performance mode.
Step 1. In the "Start" menu and search "power."
Step 2. Choose the "Power and Sleep" option.
Step 3. Now choose the "Additional power Settings" option.
Step 4. Choose the "Power mode" option and select "Best Performance."

Clutter on your drive can slow down the SSD write speed, but don't worry, it's easy to fix with the Qiling Disk Master tool.
You can find the information on how to free up hard drive space by following the link below.
To free up hard drive space in Windows 10/11, start by deleting unnecessary files and documents. Then, use the Disk Cleanup tool to remove temporary files, system files, and other items you don't need.
If your computer is cluttered with too many applications or games, or if you're running low on storage space, you're not alone. Many people struggle with the same issue, and it's often a sign that it's time to clean up and free up some space. Whether you're looking to make room for new software, or simply want to declutter your digital life, there are ways to tackle the problem and get your computer running smoothly again.
Fix 9. Check Your SATA Port
Most motherboards come with SATA 3Gbps/SATA 6Gbps ports, which significantly impact the performance of your SSD. To determine which type of SATA port you have, it's recommended to consult your motherboard's manual, as it can be challenging to visually identify the port.
Intel SATA controllers are commonly found on motherboards with Intel chipsets. It's recommended to use the fastest available SATA port, usually labeled as such, to achieve optimal speeds.
- Notice:
- M.2 SSDs are becoming popular, offering high performance with the NVME standard. Ensure your motherboard supports M.2 SSDs to take advantage of this technology.
Fix 10. Check Your SATA Cable
The condition of a SATA cable, whether it's torn or of poor quality, can affect the SSD's write speed. It's a good idea to check the cable's condition and only purchase a SATA cable from a reputable manufacturer to ensure optimal performance.
To troubleshoot the issue, ensure the cable is properly slotted and securely connected, and try re-seating it for a snug fit.
