Question about Samsung Portable SSD T3

I use the SSD on a notebook (Asus GX700VO) and there as a "data hard drive"! Unfortunately, the notebook only has 2 NVMe (M.2) slots where the system and the programmes are on it (in RAID 0)!
The Samsung SSD is connected via USB-C and fully meets my requirements for a "data partition"! The Asus notebook is stationary and therefore the permanently connected SSD is absolutely no problem!
Regarding the question: You will never be able to reach the speed of the built-in SSD of your MacBook Pro with it, because it is connected similarly to my Asus. In your case it's a proprietary PCIe connection, which is certainly comparable to M.2 but not compatible! You can't get to it with "USB" even if it is "USB-C"! Nevertheless, I think you can achieve what you want with it!
