Why P2 Cards Eventually Die

p2cardsAmanda Emily (photog, historian and technical genius) posted a brilliant explanation of P2 cards on her site, AmandaEmily.com.

With the new E-Series P2 cards coming out, the question arose about why a P2 card “goes bad.”

Amanda takes a stab at it, and explains it well with nice and simple charts and graphs.

Think of a flash cell as a kitchen sink. One side is called the source, regard it as the faucet. The other side is the drain, which works just like a real drain. In between the source (faucet) and drain is a gate blocking the flow of electrons (water). When the gate is closed, there is no electrons flowing (water) between the source (faucet) and drain.

Thanks to Amanda for breaking it down for us.

  1. This is why I rent P2 cards if I need more than one. I can’t bring myself to pay so much for something that will go bad eventually.

    P2Rents.com is the best source I know of for this.
