Size is limited by cost -- and the willingness of the market to pay it.

You can buy SSDs with capacities measured in terabytes. However, they come with pricetags measured in thousands. The cheapest SSDs today generally run around $0.70 per gigabyte. HDDs in contrast cost as little as $0.04 per gigabyte.

The real benefit for SSDs for the home user is quick retrival of small files. Thus you want not only the OS but your various applications, including games, on your SSD. Load a few 15-20 GB games onto a drive and even a 128GB capacity is quickly strained. It is generally more cost effective to buy a larger single SSD than a couple of smaller drives, plus because of the way SSDs work larger drives enjoy a significant performance advantage.

As for data storage, retrival of sequential data from large files isn't greatly affected by the speed difference between SSDs and HDDs. When playing a movie or a song, you don't need to deliver the whole file in three seconds. As a result, those files which cost the most to store benefit the least from expensive SSD storage. There's little to gain from spending ten or twenty times as much to store your media files.
