SSD also has limited "write" times, so, defragging the thing would end 
up re-writing the data, and thus hastening the death of the media. Its 
why most OSes that use them are "tweaked" so they never, if possible, 
write the same file back to the same sectors each time, they way you 
would on a HDD.
