SSDs are expected to be superfast to get your slow-duck PC to a responsive beast in seconds. Do you own an SSD from a trusted company like SanDisk but are still experiencing SanDisk SSD slow issues?
However, you shouldn't worry about the SanDisk SSD slow error. This article offers simple and practical solutions to get the best speeds out of your SSD.
Numerous hardware and software problems, including other factors, could be blamed for the SanDisk SSD slowdown. However, because hardware problems are challenging to resolve, purchasing a new SSD is the most effective option.
Fortunately, if the hardware works correctly, you can still fix the issue once you identify what is slowing down the SanDisk SSD. Here are some possible causes that could account for the SanDisk SSD slowdown problem:
- The ports you're using are incompatible or incorrect.
- Limited available SSD disk space.
- PC or SSD firmware issues.
- Hibernation is enabled.
Besides, to determine SSD slow error, you can use the SSD benchmark tool to test the speed of SSD easily and quickly. Then, you can jump to the next section immediately to learn how to fix this now that you know what might have caused the problem.
The following excellent solutions will help you quickly recover system performance lost due to SanDisk SSD's slow speeds:
- 1. Disable Hibernation
- 2. Align SanDisk SSD Partition
- 3. Make SATA Controller Runs in AHCI Mode
- 4. Securely Erase SanDisk SSD
- 5. Check SanDisk SSD Port
Look at the step-by-step guides to fix your SanDisk SSD slow error:
Hibernate, also known as Sleep Mode, is very useful for HDDs because it enables the disk to load applications faster than the system boots, but it is not required for SSD drives as their boot speed and time are already sufficient.
Moreover, the "Hiberfil. sys" file consumes much space and RAM resources. So, it's preferable to disable the option to free up disk space and improve SanDisk SSD performance.
Follow the steps given below to disable "Hibernation" on your PC:
Step 1. Press the "Start" button and type cmd. (Make sure you run the command prompt as an administrator.)
Step 2. Type the following command - powercfg.exe/hibernate off and press the "Enter" key.
This disables "Hibernation" and allows your SSD to work without any slowdowns or speed issues.
4K alignment allows SSDs to read and write data at the fastest possible speed. It is best for maintaining performance. It's not difficult to align your SanDisk SSD partition. You can optimize your drive and boost system performance using a secure third-party partition tool like EaseUS Partition Master.
Once you have installed it in your system, you only need to use its SSD 4K alignment feature to clean up junk files, optimize the disk, and remove large files. Here is a detailed guide to using it:
Step 1. Go to "Toolkit" and choose "4K Alignment".
Step 2. Select the disk you want to align. Click the "Start" button.
Your SSD has now been successfully aligned and optimized. You can also use EaseUS Partition Master's built-in feature to remove all the unnecessary files to free up more disk space and boost performance even further.
SanDisk's solid-state drive's high performance is superbly maintained by AHCI (Advanced Host Controller Interface) mode. The SSD may therefore operate and respond slowly when it is disabled. Therefore, switching your SSD from IDE to AHCI mode is preferable.
Follow the below-given steps to enable AHCI mode:
Step 1. Press the "Windows + R" keys and type msconfig. Now press the "Enter" key.
Step 2. Under the "Boot" tab, select the "Safe Boot" option and click "OK."
Step 3. Repeatedly hit the "F2" or "DEL" keys to restart your computer in safe mode. Change "SATA" mode to "AHCI." Then exit and reboot after saving the settings.
Step 4. This time, Windows will start in "Safe Mode." Restart your computer after starting to type msconfig once more, unticking the "Safe Boot" option under the "Boot" tab.
This ensures that the "SATA" controller operates in "AHCI" mode and offers you the best possible performance for your SSDs. And you can run an SSD performance test to know whether this method is efficient.
If you haven't been able to resolve the SanDisk SSD slow error yet, erasing all data on the SSD is another practical method to improve its performance. Data on a hard drive can be completely erased using the Secure Erase technique, which uses a set of commands.
EaseUS Partition Master simplifies the command line process and can help you securely erase data without damaging the SSD. As a result, you can easily clean up your SSD, even if you are a novice.
Because all the data will be deleted completely, this method is also beneficial if your SSD is infected with malware or a virus. Follow the steps below to clean a SanDisk SSD and fix its slow speed issue:
Step 1. Run EaseUS BitWiper. Click the "Wipe Disk" tab.
Step 2. Select the targeted HDD or SSD to wipe.
Notice: Please make sure you have chosen the correct HDD or SSD. Once the wiping starts, your data is irrecoverable.
Step 3. Choose Wiping Method and click "Next".
Choose a suitable wiping method. Recommend EaseUS Secure Erase!
Step 4. Check the warning message and click "Wipe" to confirm.
Step 5. Wait for wiping finish and click "Done".
The port on your computer to attach your SSD should be compatible with your SSD. The fastest speeds will be on a USB-C, Thunderbolt, or USB-A 3.2 Gen 2 port, NVME for external SSDs, and M.2 SSD. The data transfer speed will inevitably be slower if you use a USB 2.0 or older port to connect your drive.
Additionally, ensure the port and cable you use are in working order to prevent connection loss issues while using the SanDisk SSD.
After extended use, electronic devices like SSDs can become slow. However, the problem typically arises if the SSD storage space is exhausted or the SSD partition is misaligned. EaseUS Partition Master is the best option for both scenarios.
The app helps you to check SSD health and optimize it for the best overall performance. Moreover, the article can help you figure out how to fix the problems with your SanDisk SSD's slow speed and restore its performance completely.

FAQs About SanDisk SSD Slow
If your questions still haven't been answered, to get them resolved as well, look over these FAQs.
1. Is SanDisk SSD fast?
Without a doubt, SanDisk SSDs are among the best external SSDs. The average SanDisk SSD provides read and write speeds of 500 up to 2000 MB/s for quick transfers. As a result, for editing and saving high-resolution photos and videos, it is an ideal and secure choice.
2. Why my SanDisk SSD is not working?
Several factors, such as hardware damage or software issues, may be at play if your SanDisk SSD isn't functioning. In addition, out-of-date device drivers, an uninitialized SSD, a lack of SSD space, the activation of "Hibernation," or a corrupted file system can also limit it. So, keep an eye on your SSD's health and keep it running efficiently.
3. How long does SanDisk SSD last?
SSDs are highly reliable because they don't have any moving parts. Most SSDs can last 5+ years, and the longest-lasting choices can stay over 10. However, the lifespan of your SSD can be determined by how frequently you write data into the flash memory.
