Memory Card Lifespan: When to Replace Your Memory Cards & How to Prevent Damage Today

Do you wonder how often you should replace your camera’s memory card? Maybe after a year or two? Maybe three? Is there such thing as a memory card life span? After chatting with a Calumet Photo associate, a tech from SanDisk, and a few photographers, I gained some information that I’ll share with those of you who may question the lifespan of your camera’s memory card.

The Lifespan of Your Memory Card

Here is what I gathered from some of the sources mentioned above. 

SD Association

SD Association states that a memory card lifespan depends on how it is manufactured. They say that the current technology, along with normal usage, typically gives the card a lifespan of 10 years or more.


A tech from SanDisk told me that SanDisk memory cards are highly reliable and durable, and exceed the expectations of their valued customers. He said that SanDisk memory cards have no such expected life span, as mentioned above, and if the card gets faulty, they will help resolve the issue. If the card cannot be fixed and is under the warranty period, they’ll replace it.

Calumet Photo

Calumet Photo associate told me that the lifespan of a memory card depends on how often data is written to it and how it’s handled physically. She said that it’s good to upgrade to newer cards annually, because the performance of newer cards may be improved. She continued by saying that sports photographers, and anyone who shoots a lot, should have backup memory cards and should get new ones annually, just to be on the safe side.


A wedding photographer showed me the memory card storage case she uses. She had numerous cards ranging from 1–8 gigabytes. I asked why she doesn’t carry 16 or 32 gig cards with her. Her response was simple. Sometimes memory cards fail, and the safe thing is to have multiple cards with less gigabytes. If all the pictures are on a 32 gig card, and that card fails, the entire wedding may be lost.


I surfed over to some of my favorite blogs to see what the pros are saying. A full-time event photographer posted the following at DPReview, ” I may do 100 jobs a year…so if I used the same card for every job I’d get 5 years lifespan.”


What affects the lifespan of a memory card is the number of times data is being written to memory cells. You may go through hundreds of thousands of data-write cycles before error messages pop up on the back of your camera’s screen. When error messages occur, and if your card has been used many times, it’s a sign to replace it or risk losing your images. It’s not necessarily how old a memory card is. What determines its lifespan is the number of write cycles.
