The device takes care of determining where it will save the data based on

I wonder if anyone can put my mind at rest regarding whether SSDs
"wear-levelling" process interfere with the data stored in free
space. With BIBM you can create partitions which are hidden from the MBR.

I run Windows I don't load the Linux partitions into the MBR (they are not
selected in Boot Edit for the Windows boot item). So when running Windows
the OS thinks the LInux partitions are part of free space outside the C
According to this article SSD performance depends on the amount of free
Unfortunately I can't find anywhere where he defines free space - is it free
space within a partition or unused space on the drive?
The question is can the SSD store data in areas which are designated as
outside any MBR defined partition thus overwriting hidden partitions?
