Solved: 6 Fixes for Samsung 990 Pro Slow Write Speed - 2024 New
The Samsung 990 Pro is a high-spec PCIe 4.0 SSD that delivers top-notch performance, making it a popular choice among gamers and enthusiasts. With read and write speeds of up to 7450/6900 MB/s, it's the ultimate 4th generation SSD.
Why Samsung 990 Pro Slow Write Speed Error Appears
The Samsung Pro 990 SSD is not immune to problems, including slow write speeds, which can be caused by a number of factors such as firmware issues, outdated drivers, corrupted files, overheating, or physical damage to the drive.
- Insufficient space: If your disk has less free space, write speed will be affected.
- High temperature: Prolonged use of games or other programs on your SSD can cause it to overheat, potentially affecting its writing and reading speeds.

- Bugs: Your Samsung 990 Pro might be experiencing slow read and write speeds due to malware or other system bugs.
- Wear: The Samsung 990 Pro, like most SSDs, eventually wears out, leading to a decrease in performance over time.
The Samsung 980 Pro's slow write speed issue can be attributed to several factors, including the use of a single controller, which can lead to bottlenecks in data transfer, the use of TLC NAND flash memory, which can be slower than other types of memory, and the fact that the drive is designed for general use rather than high-performance applications, resulting in a slower write speed. Additionally, the drive's software and firmware may not be optimized for write-intensive workloads, further contributing to the slow write speed.
Before fixing the error, it's recommended to test the speed of your Samsung Pro 990. This will give you an accurate read/write speed, allowing you to know how fast or slow your SSD is.
How to Test Samsung 990 Pro Read/Write Speed
You can check your Samsung 990 Pro's read/write speed using Command Prompt, but it requires typing a few lines of commands, which can be intimidating and potentially lead to data loss if you're not experienced.
You can easily run a speed test on your Samsung 990 Pro SSD using a third-party app, such as Qiling Disk Master. This app's "Disk Mark" feature allows you to check the read and write speed of your SSD in a safe and user-friendly way, making it accessible even for beginners.
Step 1. Launch Qiling Disk Master, and click the download button to activate the "DiskMark" feature under the "Discovery" section.
Step 2. Choose the target drive, test data, and block size from the drop-down boxes.

- Run USB flash drive speed test
- Check external hard drive health and speed
- Check SD/microSD card health
This tool can 4K align storage devices based on their health condition and speed performance, making it a multifunctional tool.
Fix 2. Run Trim Command
To run the Trim command on your Samsung Pro 990 SSD, follow these simple steps: Enable TRIM in your BIOS or UEFI settings, then run a disk cleanup tool like CCleaner or a built-in disk cleanup utility, and finally, run the Trim command using a command prompt or terminal. This will ensure that your SSD's controller erases data immediately, preventing unused blocks from remaining blocked. By doing so, you'll optimize your SSD's performance and maintain its overall health.
Step 1. Start Command Prompt and run it as administrator.
Step 2. In the new window, type "fsutil behavior query DisableDeleteNotify" and hit "Enter."
Step 3. If you get a result of "1" indicating that the TRIM command is disabled, type "fsutil behavior set DisableDeleteNotify 0" and press Enter.
Fix 3. Check Samsung 990 Pro Health
