Are external HDDs really that prone to breaking? (Looking to buy one)

I've heard of people complaining how they easily break but so far i never had any problems with internal ones even though i moved my PC from time to time and as they are the exact same hardware as external i was wondering if having one and moving it from from one city to another every week would really be that bad for it?

For context, I'd just be moved from one place to another and then be left there until i move back and repeat and I would use it just for music, movies and that kind of stuff for my laptop nothing really THAT important i would need a backup.
