Last time I looked into the amount of free HDD space to reserve for Windows was on WinXP 32-bit, the advice was then was to keep 15%. HDD free  And indeed, I noticed Windows slowing at around 18% free space.  
 
I now have a i5 NUC Win7 Pro 64-bit with 256GB SSD & 8 GB RAM.   As the OS and Storage technologies are very different from before, particularly SSD which I read also needs space set aside for gradual degradation of storage cells, does the advice differ from the WinXP & HDD era ?

FWIW:  I don't think that there is a "correct" answer to give...but I see no reason to treat a drive with the O/S on it...in the same manner that I treat a drive used totally for storage.  I can cram items on a storage drive to the point where Windows tells me that I don't have sufficient space to store anything more and that's fine...since I don't claim to understand the complexities of a Windows O/S, I treat it with more respect and, honestly, I fail to see the point of creating a situation that may impact total Windows performance, if I don't have to.

 

No one has to...in this age of external drives, humongous internal hard drives, and other storage techniques available.

 

I take it for granted that everyone understands that SSDs (right now) are drives for the O/S...not for mere storage of data files which can be more appropriately stored via conventional methods.  Apparently, I'm wrong in taking it for granted.

As my firstpost on this forum 25/8/14 remains unanswered, apart form 1 respondent who thought it not worth answering as SSDs so cheap, not worth thinking about, just throw money at a larger one, I will answer my own question before trying a further question to bleepingcomputer
 
But first, the respondent who assumed SSDs so cheap just buy another, that may have been valid if I lived in the USA or Europe where competition drives prices down, but where I am there is 60% import duty on electronics items, and not being wealthy, I have to choose carefully what I import.  Whereas 500GB was the typical HDD size for systems sold at the time of my question, I could only afford to buy half that size.
 
As the question of how much space to reserve for 'Windows' was a common question when HDD was the norm, having not seen that updated for SSDs, I thought to put that as my first question when registering on bleepingcomputer
 
With no other respondent other than hamluis, after waiting a month I searched Tomshardware forums and found several replies to the question from which I gathered it was best to reserve 10 to 15% unused space for the following 2 reasons:
1)  less than 10% unused space will result in increased 'wearing' of the SSD leading to reduced drive life.
2)  less than 15% unused space will result in slower speed.
