I think google is your friend here. 🙂 General questions like what an SSD is and how it works are probably better researched that way.
Once you understand the technology a little better, you can make a more informed choice about whether you'd like to install one in your G74. If you decide to proceed, and have specific questions about installing it, there are many threads about that on this forum, and lots of owners who will be happy to help with specific issues or concerns.
