Choosing the Best SSD for 3D Modeling

I am looking at purchasing a solid state drive for my os, zbrush, maya and photoshop. Some examples of what I am looking at are:

GSkill Phoenix III
Samsung 840 Pro Series

The main difference between the two is that one has faster random(iops) read/write and the other has faster sequential read/write speeds. I would like to know if a ssd will make a significant difference when running zbrush, maya and photoshop, and if it does, whether random or sequential read/write is more important. Also if you have a recommendation that is better than either of them, please let me know. I am trying to be a little price conscious.
