I disagree.

Just because it is solid state does not mean that it does not fragment.
Fragmentation has more to do with the OS than the physical platform.

Regards,
The engineers tell me the files can't be fragmented. That every time
you save to a solid state card like SD the the entire contents of
every file is re-written to the card in contigous form. This from
engineers I know who worked at HP.


Get some better engineers. An SD card's memory has a limited number of
times that it can be used and rewritten. To get around this limitation the
card uses different areas of its memory at different times, greatly
extending the life of the memory cycles to the point that it is quite
practical. But it is not always a contigous block.

As for defragging a SD card, that is not required, nor would I recommend it.
After all, the card is managing itself quite well, and rearranging the
memory locations used will probalby not result in a contigous block in any
means - that is, if the card is doing as it is supposed to and utilizyzing
all available memory location evenly.
