No, any 2.5" sata drive that can be formatted by your 360 (you will need to write down your S/N, cause you need it to format). JTAG required, of course.
Biggest 2.5" drive that WD makes is 640GB, so if you can afford one, get that or the 500GB.
BEVT 5400rpm drives are silent and cool, so don't go for faster ones, no need.
Have fun
