Multi-level cell chips are found in most lower cost SD cards. Each of the cells stores a voltage and the level of the voltage represents a number of different values. Memory cells are insulated in order to prevent the charge leaking away. However, this insulation is eroded every time a write action is performed. Over time, this can result in the voltage in a cell changing slightly, which can cause the data on the SD card to become corrupted.
Most modern SD cards are designed to detect these problem cells and avoid them, but over time, if there are too many, the card may not have enough memory to map them. The exact lifespan of an SD card depends on a number of factors. Pinpointing exactly when you replace your SD card if difficult due to the varied pressure people put them under. The chances are that your SD card will physically stop working due to damage before it starts corrupting your data.
SD cards are made with cheap components to keep the costs down, and as such, are very prone to breaking. One thing that SD cards are definitely not suitable for is long term storage, due to the charge in the cells leaking over time.
The best practice for keeping your data safe is to copy it from your SD card to your computer as soon as you can. Simply phone or email us for a job number and send your data recovery to us.
Your hard drive or media will be photographed, catalogued and bar-coded and the data recovery evaluation will start within an hour of receipt. We aim to complete this process within 24 hours depending on the complexity of work involved.
The engineers will provide a no obligation recovery prognosis, with a guaranteed list of recoverable files and an estimated timescale. You can then decide whether to proceed with the recovery. Should you choose not to proceed, we will return your media by secure data courier. We will then copy out the data to your preferred choice of output media - either 64Gb memory stick or HDD for purchase or loan.
Your data will be dispatched on our secure, next day courier service. Once you have received your data any copies of your data will be permanently and securely erased from our servers after 7 days. With extensive data recovery research and development capabilities, our success rates are second to none - without compromising on our prices!
This is why over 36, companies and individuals come to us every year. Great care is taken when recovering and handling your data to ensure that its integrity is maintained and that there is a clear audit trail through the entire data recovery process. Class clean rooms, specialised platter removal jigs and software applications allow us to provide the most comprehensive service in the industry. They are great at communicating findings and keeping you up to date with recovering any lost data.
We had a corrupt video file recovered using the express service and the work was completed very quickly. They were very clear from the outset about what may and may not be possible and what the cost would be. From my device being collected by a courier, to a new device being sent back to me only a matter of days later, they were in touch every step of the step way to let me know what was happening. The recovery of my data was carried out extremely efficiently.
This anecdote probably offers some insight into the question at hand, but I think the reader's question deserves more attention. But is this wisdom, or an old wive's tale? The truth is that time has less to do with the longevity of a memory card than the number of write cycles. That means that number of times that data is written to the card. What this all means is that, according to the card manufacturers, you could fill a memory card every day for a couple decades without having any problems.
This reliability is thanks to a technology in the controller of memory cards that tells the camera where to write the data in the card. This technology spreads the data writes across all cells and blocks of the cards, and significantly reduces the wear and tear on certain areas of the card. This is the technical answer discussed above may be convenient for a scientific analysis of the problem, but in practice it doesn't quite work so nicely.
In my own experience, the 2 year mark seems to put a target on the back of my memory cards. The problems arise from a few sources. First, I am brutal with my memory cards. I toss them in my bag of gear, take them in and out of the card reader multiple times per day, and occasionally blend them up in a smoothie for a little extra flavor. This wear and tear has no effect on the card's internals, but it can chip off pieces of plastic on the outside of SD cards that get brittle after time, and can even bend the pins on a CF card.
I have also had cards fail when the tiny metal connectors became corroded from the humidity in Southwest Florida, USA. I usually use cards until they die, but I never shoot weddings or other important shoots on a card that is two years or older. I know that cards can easily last MUCH longer, but I've seen enough failures to know it's not worth the risk for me personally.
One last consideration is that brand new memory cards have a slightly higher failure rate. In theory, they are tested before leaving the factory but I have seen many memory cards reported as being DOA.
Consequently, I'd use a card for a couple weeks before shooting something vitally important like a wedding. Just thought I should include this short answer from Jeff Cable, as well. Jeff is a photographer and Lexar employee and wrote an answer to this question in a comment on the post from a few days ago. Unless you format your card 10 times a day, it should last a lifetime. And…of course…if you have a Lexar Professional card, it has a lifetime warranty and can be replaced if anything does go wrong.
Thanks for this detailed response, especially the info on the write cycles. It makes sense that high frequency usage would compound wear and tear on the electronics. Do you have any information on the lifespan of budget triggers like the Cactus V4? Maybe another blog post?
I have a permanent solution for all of you. I have 12 4GB CF cards I have been using for three years, and will continue to use… but… I think I will buy some of those Lexar cards with the life time warranty for this years weddings! This is my first response to one of your blogs but I wanted to say thanks for all of your information. I even have an old IBM micro-drive, both cards are used today in my D Please folks, something to keep in mind about any lifetime warranty: You might get the card replaced, but you might not get the data replaced.
