[6 Ways] How to Fix Samsung 980 Pro Slow Write Speed

Why is my Samsung 980 Pro so slow?

Samsung 980 Pro SSD represents the pinnacle of solid-state drive technology, with lightning-fast read and write speeds that can significantly improve system performance. With a PCIe 4.0 interface and NVMe technology, this SSD delivers unparalleled data transfer rates, ensuring fast access to your files, apps, and games. That's not surprising considering the drive is rated for up to 7/5 GBps of sequential read/write throughput and 1 million IOPs.

However, the Samsung 980 Pro SSD has a lower write-durability rating than the previous SSD 970 Pro. So some users may find their Samsung 980 Pro slow write speed. The Samsung 980 Pro may experience SSD slowdown under certain conditions due to several factors, including:

◕ High Temperature: When the temperature is too high, the SSD will slow down to prevent damage.

◕ Heavy Workload: Lots of large file transfers or continuous writes can slow things down.

◕ Inadequate drive capacity: If your disk does not have enough free space to hold more data, the write speed will suffer.

◕ SSD wearing: Excessive writes may cause SSD to wear out, degrading the SSD's performance.

◕ Outdated Software: If your SSD's software isn't up to date, it may not run as fast.

◕ System Settings: The way your computer is set up affects the speed at which the SSD writes data.

Then how to fix the Samsung SSD slow write speed issue? Let's continue to read.

How to fix Samsung 980 Pro slow write speed

This part will introduce 6 ways to address the Samsung 980 Pro slow write speed issue. Follow the comprehensive guide below to increase your hard drive speed and make your Samsung SSD run faster and smoother.

Way 1. 4K Alignment to optimize Samsung 980 Pro

Optimizing drive performance with 4K alignment is a smart technology that ensures partitions are accurately aligned with the physical storage space on the disk. This alignment improves data processing efficiency and minimizes the need for the SSD to access multiple physical sections during file operations. Proper alignment significantly increases Samsung 980 Pro speeds, ensuring your SSD runs at peak performance.

To easily achieve 4K alignment for your Samsung 980 Pro SSD, consider using AOMEI Partition Assistant Professional, which comes with a user-friendly "Partition Alignment" feature designed specifically for SSD optimization.

Here's a simple guide to aligning partitions to increase Samsung 980 Pro read write speed:

Step 1. Install and launch AOMEI Partition Assistant Pro to access your disks and partitions.

Step 2. Right-click the partition you want to align.

Step 3. Navigate to Advanced and select Partition Alignment from the options.

Step 4. In the pop-up window, select 4096 Sector for optimal alignment, or keep the default settings.

Step 5. Click OK to confirm and continue with the alignment process.

Step 6. Click Apply and Proceed in the upper left corner to start the alignment.

★Tips:

A system restart may be required for alignment changes to take effect, especially for system drives.

For Windows servers, consider exploring the Server Edition for extended functionality.

Way 2. Free up space on Samsung 980 Pro

As mentioned above, one of the reasons that Samsung SSD slow write speed is low disk space on the drive. The potential culprit could be unnecessary applications taking up valuable disk space. Clearing out these unused programs can help optimize your SSD's performance for more efficient tasks.

Follow these simple steps to remove unwanted apps:

Step 1. Press Windows + I keys to access Windows Settings.

Step 2. Click Apps.

Step 3. Select the Apps & features section to view all installed apps.

Step 4. Identify and select the rarely used software and click Uninstall.

Step 5. Repeat this process until all unnecessary programs are removed.

Once completed, verify that the SSD is functioning properly.

Way 4. Check Samsung 980 Pro SSD Health

Checking the health of your SSD is critical to identifying potential issues such as bad sectors or a damaged file system. Once you find out disk health issues, you can fix them in time to improve your SSD performance accordingly.

For this purpose, it is highly recommended to use the AOMEI Partition Assistant Pro discussed in Way 1. This comprehensive disk health analyst can help you check the Samsung 980 Pro health and fix this Samsung 980 Pro slow write speed issue.

Please follow these steps to check the health of your 980 Pro SSD:

Step 1. Start the program right-click on the drive you want to check and select Check Partition.

Step 2. Select the Check partition and fix errors in this partition by using chkdsk.exe option among the three available methods and click OK.

Step 3. After repairing the bad sectors on the target hard drive, click OK to continue.

After completing these steps, verify that the slow performance issue on your Samsung 980 Pro has been resolved.

Way 5. Run the TRIM Command

TRIM is an important command that helps your operating system manage data on your SSD efficiently. When you delete a file, the SSD's controller may not delete the associated data immediately, leaving the space occupied and unused. The TRIM command solves this problem by marking deleted data as unnecessary, allowing the SSD to reclaim and utilize space efficiently.

To execute the TRIM command to fix Samsung 980 Pro slow Windows 11/10, follow these simple steps:

Step 1. Open the search bar and type cmd, then right-click on Command Prompt and select Run as administrator.

Step 2. In an elevated command prompt window, enter the command:
