I currently have a 128gb m.2 ssd C drive and a 2.5 inch 1tb hdd. I have been getting slow read writes on the hdd as well as a SMART warning. I'm wondering if i should upgrade my m.2 to a larger ssd and get another hdd or if i should just replace the hdd with a larger ssd and keep my small m.2? I currently have about 500gb of games and media on my hdd. My pc is a ASUS GL702VM laptop.
