SSDs are an excellent addition to your PC. They are significantly faster than traditional hard drives (HDDs) and provide quicker data transfer rates and enhanced responsiveness. However, without optimization, SSDs can become slower and eventually cease functioning properly.

If you're experiencing slow SSD performance, follow the guide below. You'll find various solutions to enhance your SSD's read and write speeds, ultimately providing a better PC experience. So, what are you waiting for? Dive in and get a more responsive system for gaming and work.

Why Does SSD Read and Write Speed Become Slow?

Before diving into the solutions, let's explore a few reasons that can make your SSD sluggish. Occasionally, you might encounter an NVMe SSD slow write speed problem; do you know why? Here are some common factors that can slow down your SSD and lead to random errors:

  • Low disk space: Make sure your drive has at least 20% free disk space, as your system sometimes uses this as a cache.
  • TRIM command is disabled or not supported: TRIM is crucial for optimizing all your drives, including SSDs and HDDs.
  • AHCI mode is disabled: AHCI is the interface between your SATA SSDs and your computer.
  • The boot sequence is incorrectly configured: Your boot settings can also impact SSD performance.
  • The computer or SSD is infected with viruses: Viruses, malware, or spyware can negatively affect your PC and decrease SSD performance.
  • BIOS/firmware is outdated: Keep your PC's BIOS updated and check for any available SSD firmware updates for optimal performance.
  • Issues with the SATA port or cable: The SATA port cable might be loose or damaged.
  • Insufficient RAM capacity: Your PC's RAM manages all activities, so low RAM capacity can slow down your SSD's read and write speeds. Close background programs and restart your PC to clear your RAM.

The above are the most frequent causes of a slow SSD. To determine the exact read and write speeds of your SSD and resolve any issues, please proceed to the next section to perform an SSD performance test.

How to Test SSD Read and Write Speed Testing the read and write speed of an SSD (Solid State Drive) is important to understand its performance capabilities. Here's a step-by-step guide on how to do it using popular software tools: 1. **CrystalDiskMark**: - Download and install [CrystalDiskMark](https://crystalmark.info/software/CrystalDiskMark/). - Launch the application. - By default, it will select the primary drive. If you want to test a specific SSD, choose it from the "Drive" dropdown menu. - Select the test size (usually 1GB or 5GB) and make sure both Sequential Read and Sequential Write are checked. - Click "All" or "Start" to begin the test. - The results will display the read and write speeds in MB/s. 2. **HD Tune Pro**: - Purchase and download [HD Tune Pro](https://www.hdtune.com/). - Install the software and launch it. - Choose "Benchmark" from the main menu. - Select the SSD drive from the list. - Click "Start" to run the benchmark test. - The program will display the average read and write speeds along with other information. 3. **AS SSD Benchmark**: - Download and install [AS SSD Benchmark](http://www.alexander-schroeder.com/asssd/). - Open the application. - The selected drive will be displayed by default. If not, choose your SSD from the "Drive" dropdown. - Click the "Start" button to initiate the test. - Results will show read and write speeds, as well as other performance metrics. 4. **ATTO Disk Benchmark**: - Download and install [ATTO Disk Benchmark](https://www.attotech.com/products/disk-benchmark/). - Run the program. - Choose the SSD drive from the "Drive Selection" dropdown. - Select the appropriate "Block Size" range for testing (usually leave it at the default). - Check both "Read" and "Write" options. - Click "Start" to execute the test. - The results will show the read and write speeds at different block sizes. 5. **Windows 10 Built-in Tool (Storage Spaces Performance Monitor)**: - Press `Win + X` and choose "Windows PowerShell (Admin)" or "Command Prompt (Admin)". - Type `fsutil behavior query filebuffering` and press Enter to check if the drive caching is enabled. - If caching is enabled, disable it by typing `fsutil behavior set filebuffering 0` (replace `` with your SSD's letter). - Open "Task Manager" (`Ctrl + Shift + Esc`), go to the "Performance" tab, then click "Disk". - Select your SSD from the list, and observe the "Read" and "Write" speeds in real-time. Remember that these tests provide a snapshot of the SSD's performance and might vary depending on the system configuration and workload.

Windows offers Task Manager and Diskpart for real-time speed tests, but they don't provide accurate data. Fortunately, the tools Partition Master is an excellent alternative for comprehensive speed testing. It can measure SSD read/write speeds along with I/O performance and latency data.

It offers a user-friendly interface that enables you to easily and swiftly perform SSD speed tests.

Step 1. Launch AOMEI Partition Assistant. Click the download button to activate the "DiskMark" feature under the "Tools" section.
