I am going to New York and I was going to record events I am going to in 4K and I know I am going to need a lot of memory for this but I am wondering what the best way to approach this with is.

I was thinking of just getting two or three sd cards 64 gb and taking a laptop and a 2 tb hard drive but I am not sure if that is the best idea so I am looking for a better idea and also for cheap but good sd cards for 4K they need to have 60 Mb write speed.
