What Causes My NVMe SSD Slow Write Speed
M.2 NVMe SSDs use flash memory to provide significant performance gains over mechanical hard drives, offering cost-effective advantages to almost any computer user due to their lack of small moving parts prone to failure.
NVMe SSDs can degrade over time due to various factors, leading to slow write speeds, which can be caused by factors such as wear leveling, garbage collection, and firmware updates, among others.
- Overheat
- Disk fragmentation
- Outdated firmware
- Low disk space error
- Insufficient power supply
- Malware or virus infection
- Your system lacks NVMe support
- Running too many applications at once
One of the most common complaints about NVMe SSDs is that they can be slow to read, which can be a major issue for tasks that require large data reads, such as video editing or gaming. To potentially resolve this issue, try the following fixes.
Fix NVMe SSD Slow Write Speed - 8 Efficient Fixes
In this part, you can get eight efficient fixes to fix your NVMe with slow write speed. These fixes also apply to fixing SATA/M.2 and other types of SSDs' slow write/read speed. Now, let's go to check and monitor the NVMe SSD speed.
Fix 1. 4K Alignment NVMe SSD
The 4K alignment feature of Qiling Disk Master optimizes your SSD's performance by maximizing writing speed and removing duplicate and junk files with just a few clicks. This feature enables users to free up unneeded allocations, effectively optimizing their SSD.
Step 1. To align a disk, select the disk you want to align, right-click and choose "Move/resize".
Step 2. Choose "Optimize for SSD(4K Alignment)" and click the "Proceed" button.
Fix 2. Run the TRIM Command
If your NVMe SSD is slow to read and write, ensure TRIM is enabled to improve garbage collection efficiency and maintain SSD speed over time. To do this, check your system's BIOS or UEFI settings to see if TRIM is enabled for your NVMe drive. If not, enable it.
Step 1. To execute the command, open the Command Prompt as an administrator by searching for "cmd" in the search box, and then launching it with elevated privileges.
Step 2. To check if the "DisableDeleteNotify" option is enabled, you can enter the "fsutil behavior query DisableDeleteNotify" command and press Enter. This will display the current state of the option, which can be either "0" (disabled) or "1" (enabled).
0 indicates that the TRIM is running, and 1 indicates that the TRIM is disabled.
Step 3. If the fsutil command returns "1", type "fsutil behavior set DisableDeleteNotify 0" and press Enter.
1. Open the Command Prompt as an administrator.

Fix 4. Monitor NVMe SSD Speed
To resolve this error, you need to know the read and write speed of your NVMe SSD. You can use third-party software, such as Qiling Disk Master Professional, to check the detailed read/write speed of your SSD. The Disk Mark feature in this software is user-friendly and easy to navigate, making it simple for beginners to use and efficiently manage their drives.
Step 1. Launch Qiling Disk Master, click the download button under the "Disk management" page to activate the "Surface test" feature.
Step 2. Choose the target drive, test data, and block size.
Step 3. Once everything is configured, click "Proceed" to begin the disk test. This will then display the sequential read speed.
Qiling Disk Master can efficiently test SSD write/read speed and also improve its performance by enhancing its speed.
Fix 5. Change Drive Boot Order
To resolve a slow NVMe SSD issue caused by a misconfigured boot order, follow these steps: ensure the NVMe SSD is prioritized over the hard drive in the boot order. This can usually be done by entering the BIOS settings and adjusting the boot order to prioritize the NVMe SSD. By doing so, the computer will boot faster and utilize the NVMe SSD's capabilities more efficiently.
Step 1. Restart your PC and open the "BIOS" by pressing F2/F8/DEL.
Step 2. Select System Configuration, then select Startup Options.
Fix 6. Free Up Space on NVMe SSD
If you've updated to Windows 10/11 and your C drive on the NVMe SSD is running low on disk space, it's a good idea to free up space by deleting large files or uninstalling unused programs to prevent slowdowns in data and write speeds.
