When I take a month long trip overseas this summer, I do plan on taking lots of photographs, mostly vacation journal type, and some videos, too.
For storage solutions, I'm thinking about taking 1) a 2TB external hardrive as a backup storage solution, and 2) multiple SanDisk 32GB memory cards, enough that each would serve as a storage, i.e., no erasing or formatting any of these cards. One card gets full, move onto the next card. The idea basically is that these cards are cheap enough now that I can adopt "all the eggs in multiple baskets" as opposed to one basket. Also, less weight and space in transporting these. Combined these two methods, I'd feel secure not losing any images. I also plan on editing as I go and store jpeg images in my 13" Dell XPS, so essentially 3 storage methods.
Since I plan on purchasing several 32GB memory cards, I just want to run this by you folks first before ordering them to ensure that I'm getting what I need for my purpose. I don't plan on doing any burst shoots, so no need for "Extreme Pro" level cards at unnecessary extra cost. As stated, only "say cheese" vacation journal photos and some videos. The following is what I plan on ordering: SanDisk 32 GB Ultra PLUS Class 10 UHS-1 SDHC Memory Card with 80 MB/s for $12.99 each. 80 MB/s should be plenty for HD video, right?
