I currently have the hp pavilion notebook 15 - ab153n and I've been wanting to replace the slow 5400 RPM hard drive it originally came with it. This wouldn't be a problem if I had some courage and actually knew how to take this thing apart however, obviously being the noob I am cannot. I've searched how to take the laptop apart and to my terrible luck is probably the most difficult laptop to take apart (in my book). Then, I thought why not just get an external SSD to hold my operating system. Upon researching, I learned using an SSD through an USB port prevents the SSD from reaching its highest potential (so it's kind of like a bottleneck). Now I am here to ask all of you, what should I do? Is having the external SSD worth it?
