Other than storage space.... is there any benefit of using an external hard drive to back up photos and movies instead of a high end, large capacity SD card or brand name, high capacity flash drive? My Dad never ever ever (I know this is hard to fathom to tech-savy people here) will use more than 8-10GB of space, he has a few old family movies that were transferred to digital files and a handful of pictures he takes with a point-and-shoot camera. I think he's up to 5GB now after 5 years or so. He won't ever end up with a collection of photos and movies that will be over 8-10GB in size. (at least not for the next few years, and even then they wouldn't fill up a 128GB SD card). So for the sake of argument, lets assume he wont ever need more than 10GB of space, is there ANY disadvantage WHATSOEVER in getting him a large capacity (I'd get a 128GB size or so, just for good measure) high-end (name brand, for the sake of dependability) flash drive or SD card he can more easily take with him for his collection (to show or share on the holidays when we all get together, or when he travels or something) or is there some quality-related (or dependability-related) advantage for using an external hard drive with the data cable? If there's even 1% of an advantage to using a slim external hard drive over a quality SD card or USB flash drive, in the areas of dependablility or quality/security, this is what I'm looking to know. *By the way, I'd get two, so he'd always have one as a backup.
