Portable (External) SSDs are essential in modern life, providing great data transfer and storage convenience. However, sometimes users may need help with slow read/write speed. Below, KingSpec will take you deeper into the causes of slow read and write speeds on external SSD and how to solve them.

1. Check for physical damage

When using an external SSD, you notice a slowdown. First, observe the indicator light; some portable SSDs have indicator lights, which will have a specific blinking status during regular operation. If the indicator light shows abnormality, it may suggest a problem. Next, check for any physical damage. Cracks or wear and tear may affect its performance. During the inspection, ensure the enclosure is intact, and the connection ports and cables are not damaged.

2. Check and replace the USB cable and USB slot

A damaged or loose USB cable or connector may cause an unstable connection to the external SSD, which in turn affects the read/write speed. When checking, try replacing the USB cable or connecting it to another USB slot. To pinpoint the issue and address it accordingly.

3. Clean the virus and install the antivirus software

A computer infected with viruses or malware may affect the performance of an external SSD, resulting in slower read and write speed. To do this, you need to run a full virus scan. And make sure you have the latest antivirus software installed to protect your computer and external hard drive.

4. Clear the disk space

More storage space on an external SSD may prevent slower read and write speeds. Unnecessary files and data on external SSD should be cleaned regularly to free up more storage space.

5. Troubleshoot your computer's hard drive

If a computer connected to an external SSD is also experiencing performance issues, there may be a problem with the computer's hard drive. Check your computer's hard drive to ensure it does not cause the read/write speed problem.

6. Optimize System Settings

By optimizing the operating system and computer software settings, the performance of external SSDs can be improved. By closing unnecessary background applications, disabling boot options, and optimizing disk defragmentation policies, you can reduce system resource usage and improve the read/write speed of external SSD.

Through the above methods, you can effectively solve the problem of slow read and write speed of external SSD and improve work efficiency and data transmission speed. It is recommended that you regularly check the status of the external SSD and take appropriate measures to maintain and optimize its performance to ensure that your work and data transfer goes smoothly.
