An internal DVD/BD drive is better protected in a PC case than a external USB drive, has a stronger case, and generally has a more robust power connections. Because it is built into the PC it is less prone to getting dropped, lost, beat-up, doused in coffer or coke, or stepped on.
External DVD/BD drives connected via USP strike me as flimsy, and some require two USP port connections for power, but they do provide a highly portable solution for road warriors.
A growing problem is modern PC cases tend to lack external drive slots and are oriented toward USB connected media and cloud storage.
