Hi,

interesting discussion about SSDs.

Theoretically, in the case described above, it would be possible to move 
'static' data (data of cells that have not been written to for a long time) to 
the 5GB in question and use the 'fresher' cells as free space; this could be 
done in a round-robin fashion. Do SSDs (or some one them) implement a similar 
functionality? Or alternatively, are there tools that do this?

David Nemeskey
