Thank you for posting on the HP Support Community.
Don't worry as I'll be glad to help, after reading your post, I did go through the Product specifications of your product and found that you have 1 TB 5400 rpm SATA hard drive installed on the PC. And your computer supports M.2, PCIe, NVMe solid-state drive with TLC. To know more about storage refer to the 6 Chapter 1 Product description: http://h10032.www1.hp.com/ctg/Manual/c05747649
