    When is it time to change your SD card? I have several that are several years old that I use over and over again. I sometimes change if I'm traveling and plan on taking 100+ photos. What's your way of doing things?
    Thanks in advance.

    A 108 views and no one apparently uses sd cards. Interesting, I didn't think it was that hard a question.

    I've never had one fail on me but... I swap them out during important sessions, back them up on the laptop as soon as possible. They've gotten so cheap I sometimes send the duplicates, after backing up, home thru the mail. I always adhere to the philosophy that cards or back in the day film is the cheapest part of the process and the most important. penny wise pound foolish is true here. better to have to many images then too few or lose any. To answer your original question i don't think they really give any warning of doom.

    I used to use them professionally in my camera. Tens of thousands of pics and had exsacy one fail me.

    I used recovery soft wear to retrieve the images and trashed the card. I still had a dozen or so of vairing sizes and some are 5 years old and work fine.

    Much more reliable than film was in my opinion.

    Thanks for the responses. I would think there would be a life expectancy somwhere, but I'll keep rotating. They say if they're not used for a period of time they will fail...never seen this either.

    Cell phone forensic school taught me that flash-memory has an approximate lifespan of 10,000 writes/erases..

    I've never had anything fail either..

    Well, there were very few if any cases of the film itself failing. Development errors, high heat, airport x-rays
    and user errors caused many problems but the film itself was pretty reliable.

    The comment on the expected lifetime for Flash Memory is a fairly good reference.

    I decided to try a class 10 SD in my phone just for grins, and I was quite surprised at how much faster it was to enter/store the file compared to a class 2. I used it for APPS and photos.

    When I count work related SD cars used by others, I have had a few failures.

    If you freeze then and thaw them in cars, it is not good for them.
    If you physically break them.
    If you play with lard magnets like MRIs...
    If you put something on them and then expect to retrieve it many many years from now.:faint:

    As for the camera, I don't think I can wear out the SD cards. The slot, sure, the camera, sure, the cards.....no.


    BTW, I am liking the micro-SD cards in converters in the camera.
