Specs of newer model WD elements?

I have an earlier model (silver case) WD Elements drive.  I’d like to upgrade from my current 500 gig to a higher capacity.

The earlier model is a 7200 RPM drive.  I can’t find any specs about rotational drive speed, cache/buffer size of the new models.

Are the new WD Elements drives 7200 RPM w/ 16 meg buffer?
