SSD configuration software Both Intel and Samsung supply windows only configuration software for their SSDs (Intel® Solid State Drive Toolbox, Samsung Magician Software for PC).  

Is there anyway to achieve the same functionality under OS X?
And/Or is this functionality actually needed?

To clarify using Intel as an example (but samsung has something similar), their configuration tool can:


  Check and tune system settings for optimal performance, power
  efficiency, and endurance


(Note that this is separate from firmware updates - which both companies do seem to support for OS X systems)
Both of those tools seem to provide some basic diagnostic information about your drive.  


  The Intel® Solid State Drive Toolbox (Intel® SSD Toolbox) is drive
  management software that allows you to:
  - View current drive information for Intel® Solid State Drives (Intel® SSDs), including:
  
  
  Model number, capacity, and firmware version 
  Drive health 
  Estimated drive life remaining 
  SMART attributes (also available for hard disk
  drives and non-Intel SSDs) 
  Identify Device information (also available for hard disk drives and non-Intel SSDs)
  


You can get this with DiskDrill or Diskwarrior.  The free versions of both can give you what you are looking for.

The "tuning" is basically enabling/disabling TRIM support.  There are 3rd party utilities out there that can do it for you, but the reccomended way is doing it through OS X Terminal.  The linked article has a Word document that provides you the steps to to enable TRIM; I am direct linking it here
