Hard disk drives in the 3½: format are still sticking with the standard form factor. The changes in the industry are with 2½” drives like the ones in laptop machines.
Historically 2½”: drives were 9.5 mm thick. It was standardized many years ago. SSD drives have been made in thinner 7 mm thick form factors. Some hard disks are now being made in 7 mm thick formats, 7 mm drives are also now being seen in some recent mobile machines to make then thinner.
There are some server chassis available that can use 15mm thick drives but these new disk models are intended for desktop use.
The Corsair 300R chassis has removable trays and they have bottom mount holes for 2½” format drives. There is room for 7mm to 15 mm easily as the trays are designed for 3½” disks, It takes 4 screws to mount a 2½” disk in the tray which can then slid in for connection.
Now some more extreme SSD drives are now using the 15 mm form factor which once again targets desktop users.

We joked with Seagate over the 60TB SSD for gaming. They understood about how bad game collections have been growing.
