I like want Trovals has to say about the new Intel SSD. For me one of the

Not entirely true.
There's no way the SSD could understand a "file". In order to do that,
it would need to understand every single file system currently existing,
and that will exist -- or only support 'approved' filesystems.
That being said, it's entirely possible that it does this on a
sector-by-sector basis, and not a file-by-file basis. But all this is
moot, because I this is how modern filesystems work, anyhow; especially
those that do journalling: each modification to a file causes data to be
written to free blocks, and then the inode for the file in question is
updated to point to those new blocks.
