The higher platter density (320 v 250) gives better performance.
The 2 drives you have listed are quite different, the samsung is an eco drive, so it supposed to be quieter and draw less power (at the cost of some performance), where as the cavier blue is a full-on drive for performance.
Are you after performance or quietness/coolness?
I have RAID5 arrays at home with 4 x 1TB Samsung F1 Spinpoint (320GB platters) and another with 4 x WD6400AAKS (640GB Cavier Blue - 320GB platters).
TBH, I cannot tell anything between them in either performance, speed or heat.
As for the "green" drives, I have zero experience I am afraid.
