>From what I have read, for most SSDs, if an already written part of an 
SSD needs to be re-written, the previously existing part needs to be 
read into the SSD's cache, 512K of the SSD is erased, the SSD cache is 
updated to reflect the updated bits, and then the 512K is restored. 
This could be a consideration if there may be multiple overlapping 
write requests.  The SSD itself does not know about partitioning and 
in fact tries to distribute the write load as evenly as possible as 
part of the wear leveling algorithm.
