Solve Slow Write Speed on NVMe SSD - 8 Effective Solutions

In this section, you'll find eight effective solutions to address the issue of slow write speed on your NVMe drive. These remedies are also applicable for resolving slow read/write speed issues with SATA/M.2 and other types of SSDs. Let's proceed to check and monitor the NVMe SSD's speed.

Fix 1: Align 4K for NVMe SSD

The 4K alignment function of Partition Master tool will maximize the writing speed of your SSD and assist in enhancing its performance. It optimizes your SSD by eliminating duplicate and unnecessary files with just a few clicks. This 4K alignment feature allows users to release unneeded allocations. To give it a try, please follow these steps:

Step 1. Go to "Toolkit" and choose "4K Alignment".

Step 2. Select the disk that you want to align. Click the "Start" button.

Fix 2: Run the TRIM Command

If your NVMe SSD is experiencing slow read and write speeds, ensure that TRIM is enabled. TRIM enhances garbage collection efficiency and helps maintain the SSD's performance over time. Here's how to do it:

Step 1. Search for "cmd" in the search box, and open the "Command Prompt" as an administrator.

Step 2. Type the "fsutil behavior query DisableDeleteNotify" command and press "Enter."

Check the Trim command

0 indicates that TRIM is enabled, and 1 indicates that TRIM is disabled.

Step 3. If the result is "1," type "fsutil behavior set DisableDeleteNotify 0" and press "Enter."

You can successfully enable the TRIM command on an SSD using this command.

Follow these tips to speed up SSD and optimize its performance: 1. Keep the SSD updated with the latest firmware: Manufacturers regularly release firmware updates to enhance SSD performance and fix any issues. Check the manufacturer's website for available updates and install them promptly. 2. Enable TRIM support: TRIM is a command that helps maintain the SSD's write speed by informing the drive which data blocks are no longer in use. Ensure that TRIM is enabled in your operating system's settings. 3. Defragmentation not needed: Unlike traditional hard drives, SSDs don't require defragmentation as they store data differently. In fact, defragmenting an SSD can shorten its lifespan. Make sure defragmentation is disabled for SSDs in your system settings. 4. Optimize power management: Some laptops and systems may throttle SSD performance to conserve power. Adjust power settings to prioritize performance when necessary. 5. Use a modern file system: If you're setting up a new SSD, consider using a modern file system like NTFS (Windows) or APFS (macOS) as they are optimized for SSDs. 6. Limit the number of simultaneous programs: Running too many programs at once can strain the SSD. Close unnecessary applications to reduce the load on the drive. 7. Use a dedicated SSD for the operating system: Install your operating system on a separate SSD rather than sharing it with other data. This ensures faster boot times and better overall performance. 8. Avoid installing unnecessary programs on the SSD: Save space on your SSD by installing less frequently used programs on a traditional hard drive or a secondary SSD. 9. Regularly clean up temporary files: Remove temporary files, system caches, and log files to free up space on your SSD. Use built-in tools or third-party software for this purpose. 10. Monitor temperature: High temperatures can negatively impact SSD performance. Ensure proper airflow and cooling to maintain optimal operating conditions. By following these guidelines, you can ensure your SSD operates at its peak efficiency and prolong its lifespan.

• Update the SSD firmware.
• Disable indexing on the SSD.
• Minimize unnecessary writing.
• Move temporary files to another location.
• Enable write caching in Device Manager.
• Create a RAM disk (with at least 3 GB of memory).
• Migrate caches and temporary internet files to the RAM disk.
