Lifespan of CF card
« on: January 12, 2008, 08:50:05 PM »
I'm wondering how many times one can record and then reformat a CF card. I have a Transcend 8gb card that I've reformatted 50 times. So far, so good, but don't want to get burned.

Transcend claims they can handle 1 million write cycles. You could probably format 10 times a day for the next 250 years or so.

Transcend claims they can handle 1 million write cycles. You could probably format 10 times a day for the next 250 years or so.
But if you count each recording as a write and each format as a write (which is an oversimplification of what actually happens), you're down to about 137 years. I think it safe to assume that some cells will be subject to premature entropy. So I'd probably round it down to an even 100 years and call it good (which also happens to be the service life estimate I read somewhere for CF cards).

 But, if you remove the card each time you format it (for 137 years) that's 499k insertions. That's well beyond the fatigue limit for insertion/removal. The connectors should wear out long before the memory does if you take it out of the recorder every time you read it.

You cannot strengthen the weak by weakening the strong. You cannot help the wage-earner by pulling down the wage-payer. You cannot help the poor by destroying the rich. You cannot help men permanently by doing for them what they could and should do for themselves.

or maybe forgo the whole rig and upload to your PC via your organic memory bank...  Better lay off the herb if you want lossless!

Advice is a form of nostalgia, dispensing it is a way of fishing the past from the disposal, wiping it off, painting over the ugly parts and recycling it for more than it’s worth.
