200 history steps available!! ??

That is excessive and poor memory management, if that is the way you 
like to work, it is not an efficient method or work flow.

Even if I work with multiple layers, I complete the intermediate 
adjustments and move on. Each of the completed layers is self contained 
and replaceable, there is no need to access them via History. I 
currently have my performance preferences set at 50 History States, and 
I seldom need to access any of those. When I do, it is unusual to go 
deeper than 10 to 20 States.

How much RAM do you have assigned to PS?
Having a fatter HDD is just going to mean more writing to your assigned 
scratch disc/partition, and that is going to be limited by the speed of 
the HDD. You will see little improvement over the performance you are 
currently experiencing. Without sufficient RAM assigned you will still 
have the same number of write/read cycles to the HDD regardless of the 
size of the HDD.

If you are not going to change your inefficient workflow to something 
more sensible, and you want to perceptually speed things up for 
yourself, do two things:
1: Get more RAM and assign a disproportionate amount to PS. (I have 16 
GB on this Mac with 10246 MB allocated to PS).
2:	Get an SSD to allocate as a dedicated scratch disc.

...but I would start by adjusting your History States from your insane 
200 to a more reasonable 50.
