Memory Cards - do they die?

I've had some memory cards for quite a while now. I use them in rotation but justdelete images and re-use. Anyone got an idea of when I should really throw any away and start again?

Just format them once in a while. They seem to last forever. I have heard of them going through washing machines without ill effect.

There are three colours, Ten digits and seven notes, its what we do with them that’s important.
Ruth Ross
And I quote:
"Individual flash memory cells have a limited lifespan. That's the bad news. The good news is that their lifespan is usually measured in the hundreds of thousands or even millions of erase/write cycles, and that the better controller designs utilize an algorithm that's designed to balance the wear across the entire card's cells."
Go here for more information on 'Everything You Wanted to Know about Memory Cards ... but, Were Afraid It Would be Alot of Reading.'
And it is. ;o) (Good stuff though.)

That's great news - they will probably outlast me!

The work of art may have a moral effect, but to demand moral purpose from an artist is to make him ruin his work.
(Johann Wolfgang von Goethe - 1832)
It happened to you Tom?

Good point - did it Tom?
I just had a feeling that I was losing sharpness in the image - only marginal, but I could see it. I've gone to another card and things seem a bit better - or is it me?

I think it’s you. After all the card just stores a collection of ones and zeros. It doesn’t matter which card you use it’s still the same collection of one’s and zeros.

What if it's missing a bit of binary though??

Then you have a corrupted file and it probably wont work.

i agree. i highly doubt a card is going to cause pictures to be blurry. I would imagine it is going to work, or its not.

No one wanted to pay to say something in my sig, so i will have to try and think of something creative now...
Stands in corner - so, it works - or it doesn't - but it doesn't sort of work. I see.

I guess that was alot of information to read in that article. :oP
Reader's Digest version and the salient facts that I unearthed ... (I am a fast reader. :o) ) ... and I quote:
"CompactFlash and SD cards are designed to automatically and transparently map out memory cells that go bad, or in some cases when they reach a predefined limit, i.e. 300,000 erase/write cycles (note that this figure is just an example; manufacturers may use a different figure). Cards should continue to function long after a few cells have expired, since even the busiest photographer's flash memory card won't start turning off a significant number of memory cells until after many years of service."
And to reiterate; " ... the better controller designs utilize an algorithm that's designed to balance the wear across the entire card's cells."

Who said that??? Actually... it's a memory stick for my Sony CyberShot which I'm dubious about. The flash cards for my Nikon are new! Maybe it's the camera getting a bit rusty? No, let's not go there!

Memory sticks also use what is called flash memory, so the same applies for them as well.
