Inspiron 3670, adding additional hard drive

We've just purchased an Inspiron 3670 with a 1TB hard drive, 8GB DDR4, 16GB Optane memory on M2 slot. As I was taking off all the stuff I want from the old computer, found out husband's music collection by itself is almost 1/2 a TB. He wants all of it on an internal drive on the Inspiron 3670. From the diagrams in support, it looks like there are spots for two additional 2.5" hard drives. I am looking at a 2.5" Seagate 4TB drive. The question is, will this system accept the Seagate 4TB 2.5" drive? I tried calling support but I cannot understand the accent and she talks way too fast. And it sounded like she was talking memory (which to me is RAM?) and not storage?

Any thoughts?
