Message: Re: Flash Memory Fragmentation – Myths and Facts (based on the FAT system)

letgo....

If you have an understanding of the of this key point, which I assume you highlighted ....

"What this means is that information that is stored in a contiguous matter is more likely to be found in the cache than non-contiguous information."

keep this in mind....e.Digital can do what this writer feels is unlikely.

With that,

"Since defragmentation involves moving non-contiguous clusters belonging to a file chain to a contiguous cluster space the process indeed does wear the storage card. However modern flash cards have a great tolerance and will last for many years of heavy writing before sectors start becoming “bad”..."

e.Digital does not have to worry about shuffling the deck to get data to a more manageable contiguous arrangement....in order to meet this condition..."information that is stored in a contiguous matter is more likely to be found in the cache"

===========

"Things get even worse from the fact that in order to change even one single byte, the entire page has to be first erased and then re-written with its contents again."

e.Digital does not worry about this issue at all. They do not have to erase (or flash) a block in order to update data.....their logical format allows them to overcome that problem.....managing virtual systems like FAT are the problem.

emit your points are on taret as well...
