Personally, I have experienced outstanding performance on my computer using an SSD in the way I've suggested with LR 4.x managing over 110,000 images. That said, my computer itself is new with 16GB RAM and a very fast Sandy Bridge CPU, and I've never done pre/post SSD LR performance testing, so I cannot point to the SSD alone as the difference maker.
Still, you cannot go wrong with an SSD (plus they are so cheap now) and you will be able to use it with your next computer.
