"This method is particularly useful for flash memory which has the characteristic of not being able to overwrite data in memory without first erasing previously recorded data."

particularly useful ...meaning that the substrate details of flash are not the only use of 445 issues.

For now, the only concern is that the memory(any memory) has a fast enough write...and managing the overwrite problem(Flashing or block erasure) of flash memory is not a problem.
