Load times are exactly the same.
At least there is no degradation to load times.
I backed up my PS4 internal drive (it's extremely easy) and intended to install a 2 TB SSD,
It is simply a laptop drive and SSD or HDD will work without modifications.
Installing a SSD internally will indeed help with load times, no moving parts to wait for.
but the cost of that approaches the cost of PS4 if you buy a quality drive.
So I decided to go with Seagate's Game Drive, then I stumbled across the Special Edition!
