Hi AidBox,
I have a GoPro Hero 4 Black, and have been using a camera since i had my accident back in sept 2012.
The GoPro is good, but the standard battery only lasts for about 3 hours maximum, so if you were riding for longer than that you would need to carry spares or buy the bacpac addon in order to record for longer.
I tend to record at 1080p and 30 frames per second, and i have a 64 GB memory card, which will hold about 3 hours of footage as well before i need to clear that down.
The quality is really good, but you just have to bear in mind the above. There is an option to loop record the footage, but that isn't something i've really used it for.
Depending on your bike as well it can be awkward to find the right mount if your looking to mount it to the bike. I use it on my helmet, but only because i ride a sportsbike and the mounts aren't very useful, although you can get yoke mounts for them, and mirror mounts.
I don't have any experience of the Drift 4K but the waterproof mount on the GoPro is well waterproof, and offers good protection for the camera from everything.
Thanks,
Rob
