+    Write-Host "- You can improve the performance of your SSD by reducing the amount of data that needs to be read and written. This can lower the wear and tear of your SSD and extend its lifespan. It can also reduce the power consumption and heat generation of your SSD, which can benefit your battery life and system stability."
+    Write-Host "- You can enhance the security of your data by making it harder for unauthorized users or programs to access or modify your files. Compression can also help you recover some data in case of corruption or deletion, as it may preserve some parts of the original file."
+    Write-Host "However, there are also some cons of using this script on an SSD, such as:"
+    Write-Host "- You may experience some CPU overhead when compressing and decompressing files, which can affect your system performance and responsiveness. This may not be noticeable on modern CPUs, but it can still have some impact on your multitasking and gaming experience."
+    Write-Host "- You may encounter some compatibility issues with some applications or games that do not support compressed files or folders. This can cause errors, crashes, or performance degradation. You may need to decompress some files or folders before using them with certain programs."
+    Write-Host "- You may lose some data quality or functionality when compressing some types of files, such as audio, video, or document files. Compression can reduce the resolution, bitrate, or features of these files, which can affect their appearance, sound, or behavior."
+    Write-Host "Therefore, you should weigh the pros and cons of using this script on an SSD before deciding to do so. You should also backup your important data before running the script, in case something goes wrong. You can read more about how compression works on SSDs in [this article](^3^) or this question."
