Is deleting and creating a file bad for your card?

The advise not to format a SDcard too frequently is understood but is there any downside from creating and deleting a file many thousands of time? All knowledgable advise welcome. Thanks and Regards Geri

You will never wear out a modern SD card with an Arduino. Cards have a virtual to physical map to spread wear.

Each area of a MLC flash chip be written about 10,000 times. So you can write 10,000 times the size of the card.

For a 4GB card this is 40TB. Formatting does little wear if you use quick format. Only a tiny amount of data is written to the card.
