Does filling up an SSD slow it down?

[Udden]

I asked this in another thread but I'm kind of eager to finish my order.
I'm thinking of getting the 128 gb ssd. It's really borderline small so I'm asking: Will filling it up impact it's performance?

Filling any drive up will impact it's performance. Try to leave 10-15% free for best results.

You can fill an SSD up to 99% and performance will not drop. Source: http://macperformanceguide.com/Storage-WhyYouNeedMoreThanYouNeed.html

However, to avoid "choking" the operating system, I suggest leaving at least 5GB free for virtual memory, spotlight indexes, etc.
