4 Solutions to SanDisk SSD Slow in Windows 11, 10, 8, 7
Real cases: SanDisk SSD running slow!
Case 1. You've recently replaced your 32GB Crucial SSD with a 120GB SanDisk SSD, but it's performing poorly, sometimes slower than your HDD and freezing. This is not typical behavior for a SanDisk drive. Consider checking for firmware updates, running a disk check, and ensuring proper driver installation. Additionally, verify that your system is configured to use the SanDisk drive as the primary boot device. If the issue persists, it might be worth exploring further troubleshooting steps or contacting SanDisk support for assistance.
Case 2. I'd be happy to help you troubleshoot the issue with your Sandisk SSD PLUS 240GB. One possible reason for the low write speeds could be the type of file system used on your computer. If you're using a file system like NTFS, it may not be optimized for SSDs, which can lead to slower write speeds. Additionally, the write speed can also be affected by the amount of free space available on the drive. If the drive is almost full, the write speed may be slower. It's also possible that there's an issue with the drive itself, such as a faulty controller or a problem with the NAND flash memory.
4 Solutions to "SanDisk SSD slow" in Windows 11/10/8/7
Compared to traditional HDDs, SSDs are much faster in write and read speed, making them a popular choice for cloning operating systems from HDDs. However, SSDs can become slow when almost full, affecting performance in Windows 7/8/10. Rather than buying a new SSD, users can try the following solutions to improve their existing SSD's performance.
- 1. Disable Hibernation
- 2. Make SATA controller runs in AHCI mode
- 3. Align SanDisk SSD partition
- 4. Secure erase SanDisk SSD
1. Disable Hibernation
Hibernate (or Sleep Mode) is useful for HDDs as it loads programs faster than booting, but not necessary for SSDs, which already have satisfactory boot speeds. Disabling hibernate can also free up disk space, as the Hiberfil.sys file can take up almost as much space as the RAM. This can be beneficial for SanDisk SSDs, which may experience slow performance.
To disable Hibernation, open the Command Prompt as an administrator and type `powercfg.exe /hibernate off` followed by Enter.
2. Make SATA controller runs in AHCI mode
Disabling AHCI (Advanced Host Controller Interface) Mode on a SanDisk solid-state drive can significantly impact its performance, causing it to run slow and respond slowly. It's generally recommended to set the SSD mode from IDE to AHCI to take advantage of its high performance capabilities. This ensures optimal operation and responsiveness of the drive.
Step 1. Press WIN+R and type msconfig and then press Enter.
Step 2. To change the SATA mode from IDE to AHCI, go to the Boot tab, select Safe boot, click OK to save the changes, and then reboot your computer into safe mode by pressing F2 or DEL repeatedly. From there, change the SATA mode to AHCI, save the settings, and exit. Finally, reboot your computer.
Step 3. Windows will boot in safe mode this time. Run msconfig, untick the Safe boot option on the Boot tab, and restart your computer.
3. Align SanDisk SSD partition
To fix a SanDisk SSD running slow problem in Windows, use Qiling Disk Master Professional, an all-in-one partition manager and disk management software, to optimize data writing and reading speed, and automatically defrag your HDD based on your schedule.
PS.: you can download the trial version.
Step 1. Install and launch the software, right click the SanDisk SSD partition and choose Move/resize Partition.
Step 2. In the next window, you can tick Optimisize for SSD option.
Step 3. Finally, click Proceed to save changes.
4. Secure erase SanDisk SSD
After using a SanDisk SSD for a long time, it can become slow due to the accumulation of data. Erasing the data on the SSD can help optimize its performance. The Qiling Disk Master Pro software offers an "SSD Secure Erase Wizard" feature that can securely erase data from the SSD.
Note: To make this feature work, first connect your SSD to a Windows 7 computer and ensure it's detected successfully.
Run the software on your computer, click "Wipe" on the top toolbar, choose "SSD Secure Erase", and follow the hints to finish the operation, then click "Wipe" on the top toolbar, and choose "SSD Secure Erase" to securely erase the SSD.
