Depend on the size of the drive. If your drive is too thick, it will not sit. The SSD used in the Mac is not the SATA3 2.5in but the PCIe drive with apple design. The display is glued to the body so you need to buy the adhesive strips to mount the display back.

That is 1TB drive and fusion drives have 128GB or 64GB depend on the model. The 3.5 are okay but too heavy and bulky so I usually use 2.5in 2TB drives for internal and the rest of data stored in external drive.
