I have an HP ENVY x360 -15z-ds000 CTO with a product number of 5NX74AV0 and when I was purchasing it, the webpage (newegg) it was purchased from had options for an HDD that I did not take. However, I do not see anything in the service manual that HP's website provides about adding a second internal drive of any variety.
Can I install a secondary internal drive? If so, what type?
