Slightly off topic, but it's often forgotten that the filesystem also plays an important role in drive performance. Newer filesystems like NILFS (http://www.linux-mag.com/cache/7345/1.html) are created to suit SSD's instead of the legacy rotating media. It claims to hold the same performance, no matter how large the filesystem is.
Back on topic: We're seeing the same evolution with SSD's now like we saw it with spinning media several years back, when they started to increase the drive size ever more. Eventually these performance differences between larger and smaller drives will disappear: they will simply not be an issue anymore at all when you won't be able to get SSD's smaller than 200GB, like the similar trend with spinning media.
