Adding hdd or ssd to hp zbook 15 g3

[Asso]

I have hp zbook 15 G3 laptop which has a 240 GB ssd hard disk and I want to add 2 tb hard disk wheather it's ssd or hdd

What hardware do I need and what is compatible with my laptop?

I actually have a Zbook 15 G3. There is a 2.5 inch bay and the mounting hardware that will allow installation is shipped with the laptop. Also there are two M.2 slots that will take either a SATA or PCIe/NVME M.2 SSD. I have three disks in my laptop. A 500 gig 2.5 inch SATA SSD, for storage, a 500 gb PCIe/NVME M.2 which is the bootdisk and then a 128 gig SATA M.2 I also use for storage. 

What kind of SSD is already installed in the laptop?

Post back if you have more questions.

My ssd is samsung 256 GB 

I don't have this "mounting hardware" what it's name so that I can get it

I'm actually pretty sure you do. It's hidden under the smart card reader. See p. 57-59. But just in case you do not it is this part 

Hard Drive Hardware Kit, includes: 848231-001
(3a) Hard drive bracket
(3b) Hard drive cable

Is your Samsung 256 an M.2 "gumstick" or a 2.5 inch type SSD?

Yes I do have the hard drive bracket but I don't have the cable that connects the hard drive to the motherboard

And I don't where can I find it or buy it

My ssd is M.2 gumstick
