External hard drives

I'm very new to GoPro and I've only filmed a few hikes so far. I'm thinking about getting an external hard drive to edit on though because my laptop is not enjoying editing videos and it's so slow. I was wondering if anyone has any recommendations about external hard drives? Is there anything I should be looking out for or avoiding?
If it matters, my laptop is a MacBook Air about 6 or 7 years old and my GoPro is a Hero 11. I will probably be updating the laptop in the next year or so but I can't really afford to replace it now so I'm hoping to use the hard drive to bridge the gap. I intend to put my videos on Youtube, so I don't think I really want to be storing copies of videos I've made but I do want to be able to edit without all of the delays.
