It is not particularly useful for me, because for my wildlife trips I use XQD cards as my primary card. I use two WD My Passport Wireless Pro as my primary backup devices on trips, as I generally do not carry a laptop with me. At present, I change storage HDDs (external and internal) every 3 years or so Cheers Jayanand On Tue, Dec 11, 2018 at 12:50 AM Brian Reid <reid at mejac.palo-alto.ca.us> wrote: > I would never trust SD cards or any other flash memory to keep data > longer than a year or two. > I know how they work inside, and the storage mechanism is very delicate, > sensitive to background radiation and random perturbations of the > universe. > > I did a presentation at NYLUG about 10 years ago about preserving > electronic images.
