Hz is just 1/sec. If you want to be technically correct, don't add any implicit meaning to it. Frequency is the rate of something happening per unit of time. That "something" can be "number of data transfers" or "number of clock cycles" or "number of times a ball hits the floor". The frequency of all of those can be measured in Hz. You should be clear about what quantity you're measuring, but the unit is Hertz nevertheless. (And MT/sec is really "some unit-less quantity/sec", so it can be accurately called MHz.)
