SANDISK.com has the papers on this. If you don't use them, then what can be said.
-> In reality out of some 500 cards we field over the past 5 years we've had 2 cards failed. But we've lost (lost, stolen, gone missing...) about 50.
SD card failure appears to be much less than other issues we have.
Hope this helps.
My company is looking to make a large investment in SD memory cards for our business because our research has told us that SD cards are the most popular camera media.
Is anyone aware of any research on the longevity of SD media, or flash memory in general? AND what is the general feeling on the lifespan of SD before it is replaced with something newer/better. Is it safe to assume we can expect a five-year availability of this media and the cameras that use it?
