Platter drive is a conventional drive (with magnetic platters that spin and store the data), what I was suggesting is that things where writes to a drive happen often like programs that use temp files (like browsers) you redirect the those writes to the platter drive and not your SSD, constant writes to SSDs can shorten their life span, your page file (if you have one is basically tons of writes (the page file is where DRAM sends data when it starts to run low so it doesn't have to recreate the data or pull it across the internet again)
