    No offense but it's "why do" not due in your topic. Anyways, my guess bigger is better??? Shouldn't make a difference except size, but if you are curious about performance than bigger is better is all i can say.

    Technically there should be no difference until the drive is full. Even then, you're going to fill the 256 up anyway, so it is a mute point. The 256 should technically last longer because it has more space to spread the data and therefore better wear leveling. But we are likely talking time frames when you have already upgraded computers 2-3 times.

    Here is the answer from the Anandtech review of the Intel 510 SSD 250GB vs. 120GB.
