Dell Inspiron 17-7779: SSD specifications?

I currently own a Dell 17-7779 that has a 1 TB hard drive that is going to fail soon based on the Dell SupportAssist tests that I have run. I would like to replace the hard drive with a fresh 1 TB SSD, and then redownload all of my software and cloud files. My only problem is that I have never bought an SSD so I am unsure if the one I am looking at will fit and work in this laptop. The SSD I am looking at can be found in this link (https://www.amazon.com/gp/product/B078DPCY3T/ref=s9u_wsim_gw_i1?ie=UTF8&fpl=fresh&pd_rd_i=B0781Z7Y3S&pd_rd_r=01352a1e-7f07-11e8-9fe1-ab6a838c6a0b&pd_rd_w=vtyTB&pd_rd_wg=gXdaX&pf_rd_m=ATVPDKIKX0DER&pf_rd_s=&pf_rd_r=1C8A819EHW1S3DVA04Q0&pf_rd_t=36701&pf_rd_p=5b410b84-5133-470d-bd03-857c26c261b4&pf_rd_i=desktop&th=1).

Will this hard drive work and fit in my computer? If I am reading the specs right then I can use either a 2.5" or an M.2 with SATAIII. I have also heard the term form factor used, but have not found it specified in the spec manual. Is this something I need to account for and does the above SSD fit the requirements?

Thanks for any help that you can provide.
