The Lexar 32GB/1000x card corruption I experienced in October kind of spooked me. I've had cards go south, fortunately not in catastrophic situations, but that one could have been well into catastrophic territory. I know this wouldn't preclude a failure, but I'm thinking about a different strategy. Don't you think the majority of card failures are caused by a speck of something getting in one of the many pin slots, or something not seating just so during one of the zillions of trips in and out of the camera/card reader. A 32 GB card offers well over 1,0000 images on my X bodies, and about 800 on the D800. Most assignments don't come close to filling two 32GB CF cards, or a CF and an SDHC in the case of the D800. What if, to limit wear, the cards always stayed in the slots and were downloaded from the camera via whatever cable you use for such a procedure.
Given the very minute failure rate I've experienced when compared to the volume of images captured over the years, this is probably overkill. Seems like it would certainly reduce wear on the cards.
....... Possible - but you will / should exercise the card by pulling it out and re inserting it to clean the pins every month or so to knock off the corrosion that will build up between the pins and their socket. It's not unusual to find high pwr cord resistance when testing patient care medical devices ( defibs, ekg, vital sign monitors, anesthesia machines, surgery tables, etc .. ) that have removable pwr cords. To * fix * this we simply remove and plug the cord back into the unit 2, 3 times and the unit then passes easily within range. Breaks that corrosion / metal against metal self cleans itself of the corrosion one can't see, which builds up between the ground pin and it's socket.
