For SSD, no. SSD is a device that mimics a hard drive with 'sectors' and 
'tracks'.
It *dynamically* (for wear levelling) maps between a 'virtual hard 
drive' and its underlying weirdness of flash RAM blocks and pages.

There is nothing the operating system can do to optimise this except 
not do multiple writes to a 'sector'  if possible.
