MicroSD Card life expectancy?

I am wondering if there have been studies that show how often one should expect to replace the microSD card in one's phone or other electronic gadget (GPS, camera, tablet, whatever).

I know lots of people have their particular "behaviors" they think might/must improve the life of the chip - but any facts from specialists who have studied the topic?

its based on usage

there is no true life expectancy on a microsd card. It all depends how often it is used. Most will be damaged long before the read/write cycle wears them out. You can find all sorts of info about this with a simple online search.

Re: why not just search?

Googling drops one into a sea of opinions without much background provided. I expected that if CNET had not performed such studies they at least might have come across experts in the field to whom one might be pointed.

I'm an electronics designer.

That has used EEPROM, flash and a majority of memory devices in embedded computers over the years.

I might be the expert here. Read my reply below but keep in mind I want to stay at a higher level without diving into MTBF and such.

I'm using MicroSD cards in car cameras.

And I think with 6 car cams I replaced one card. The card was smallish so it get used over and over a lot. By moving from 2GB to 32GB that's going to extend the lifespan on paper by 16 times. So the 1 year I got from a 2GB card should mean about 16 years on the 32GB.

Car cams continuously write to the card so that eats away at it's write cycle life span. For a phone there's not so much writing and then what if you installed a DVR type app? Well it could drive the life span down.

-> This all depends on use and environment. The car cam takes it to the extreme with heat, cold and constant writing. It's the only device where I wore out cards.

Ummm...

The only real answer is that they usually work as long as you have them, but sometimes they fail unpredictably. And I haven't noticed any different behavior between cheap ones and expensive ones.
