How To Fix Windows 10 Slow SSD Issue

Windows 10 is considered as the best version of the Windows operating system. It was first released in 2015 and since then has had several major software updates. This operating system runs fast on a regular HDD but its performance is even better when installed on an SSD. This is because the SSD has a much faster access time when compared to the fastest HDD. There are however instances when certain issues can occur when using an SSD. In this latest installment of our troubleshooting series we will tackle the slow SSD issue in Windows 10.

How To Fix Windows 10 Experiencing A Slow SSD Issue

Before performing the recommended troubleshooting steps for this particular problem I suggest that you try restarting your computer first. This will refresh the operating system as well as remove corrupt temporary data and is quite effective in fixing most software related issues.

There are several factors that can cause this particular problem ranging from an old firmware version to an unoptimized settings. Listed below are the troubleshooting steps you need to do to fix this problem.

Check the TRIM setting

TRIM allows for the improvement in the writing of data to the SSD as well as contribute to a longer SSD life. You should make sure that this setting is enabled.

  • In the search bar type cmd
  • Right-click Command Prompt and click Open as Administrator
  • Type fsutil behavior query DisableDeleteNotify and press Enter
  • If you get 0 as a result, it means TRIM is already enabled. If you get 1, please make sure you follow the next steps
  • Type fsutil behavior set DisableDeleteNotify 0 then press enter.

Check if the problem still occurs.

Optimize the drivers

If your SSD drive is not optimized then this can cause the slow SSD problem.

  • Click Start and in the search bar type Defragment and Optimize Drives
  • Click Defragment and Optimize Drives
  • Highlight your SSD and click on Optimize

Check if the slow SSD issue still occurs.

Make sure AHCI Mode is enabled

  • Open Device Manager
  • Expand the IDE ATA / ATAPI Controllers
  • If you see AHCI Controller in the list, you have it enabled. In case you see only ATA and IDE words you are likely to have AHCI disabled on your computer

If it is disabled then you will have to enable it.

  • Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStorV and set the value named Start to 0
  • Find the key KEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStorAVC\StartOverride and set 0 to 0
  • Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci and set Start to 0
  • Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci\StartOverride and set 0 to 0
  • Restart your computer
  • Go to UEFI/BIOS firmware settings, enable AHCI mode, save and exit
  • Restart your computer

Check if you are still experiencing the same issue.

Change the boot order from HDD to SSD

  • Restart your Windows 10 computer and boot into BIOS
  • Make sure to change the boot sequence of HDD and SSD by giving first priority to SSD

Check if the issue still persists.

Update the firmware to improve performance

You should check the SSD manufacturer website for any updates to your particular SSD model firmware. If an update is available then you should download and install it. Check if you are still experiencing a slow SSD issue.

Optimize the SSD to reduce boot time

  • Search for Disk Cleanup in the search bar.
  • Select the SSD drive and click OK to launch the process
  • Delete the detected junk files
  • In the Start menu search for defrag and open Defragment and Optimize Drives
  • Select the SSD drive and click the Optimize button

Try to check if this fixes the problem.
