Is there a physical limit to rewriting a flash card?

[yoda313]

So I have a rio s11 mp3 player which uses sd memory cards. I plan on erasing and reusing the same discs quite often (I already have done so the last few weeks since i bought it).

I was wondering if there was a theoritcal limit to the number of rewrites on a memory card??? Since the dvd-rw has a supposed maximum rewrite I thought the memory card might have the same thing. Does it?

Just to answer my own question I guess not. I have a sony digital camera that uses memory sticks and I've had it for several YEARS. I don't know how many times I've overwritten those sticks but I guess they're pretty sturdy.

Unless somebody has a study to post about any limits I'll assume the normal user won't outlast a memory card.

Why do you presume that the SAME physical limits apply to two different media format cards ?? sony ca [/i]rds may be better engineered to withstand multiple R/W cycles ? and that is why they cost so much, not just that they are very overpriced proprietary formats( ha!) .. but yes memory cards do have a duty cycle and will eventually have to be thrown away, but its probably in the 100,000 s

Yep Playstation memory cards are the same way. After several thousand writes they build up electronic overhead and start corrupting data.

I have a compact flash card that has easily been filled and erased a couple thousand times. It has yet to fail. Burned media has a shelf life because of it's dye I've heard, but I've also re-burned CD-RW media without failure. Both media is too new for any extensive experimentation to be reliable.
