My response follows below:
Thanks for your message. I don’t think we are idiots at least my own 20 years of expertise in the field tells me we are not.
Although storage cards do not have movable parts they still benefit from defragmentation because:
1) Storage card memory is not RAM. Storage cards are always accessed in blocks of several kilobytes. So to read even 1 byte you have to read the entire block. When files are contiguous access is faster because they are block aligned. If you have a 3K file that occupies 6 clusters 512 bytes each in different locations on the card the block driver will have to read 6 blocks from the memory card. If the file is contigious all blocks will likely be read in one single block.
2) Fragmented file systems cannot be easily recovered with data recovery software. It is a good idea to keep your files defragmented in case anything bad happens and you decide to undelete files or scandisk the storage card.
So with all my respect to the posts you mentioned I do not think we are such an idiots you are making us look like.
If anybody wishes to comment I will be happy to start a discussion on the topic.
