SSD and hidden partitions
Posted: Tue Oct 18, 2011 8:56 am
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.
For example I have a 25GB Windows system partition (C drive) in my SSD, 2 Linux partitions (around 10GB each) and the rest is free space. However when 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 partition.
According to this article SSD performance depends on the amount of free space

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?
