I understand that you could immediately take a flash drive with USB 3.0/Type-C and not worry, but I really liked the design. I use it together with an adapter to Type-C for a phone, but I also encounter old phones with a mini-USB connector. I took 64 GB: in terms of price / volume ratio, as for me - the most optimal flash drive.
