There has been a lot of discussion on External Batteries and number of mAH for a Thru Hike. What about Data Storage / Pictures and Video from Camera Roll. I have an I phone 6 with Lifeproof case and 128gb of Storage. Suggestions on a Disc or Drive that will work with the case on and how many gb’s if any are needed? Cost is also a consideration. 128 goes for around $100 it seems, while 64 goes for $60 and 32 for $20. I just spend $69 to for Insect Shield so I am down to the last few gear dollars before departing for the trail. Asking because Amazon Reviews are all over the place as to Positive or Negative experiences no matter which Drive or Company, although Kingston was the favorite but also the most expensive for storage space.
