The higher the power use, the lower battery life.
For a 55Wh battery pack, if it normally lasts 3 hours, that's a power
draw of 55Wh/3h = 18W.
If you add on another watt by increasing the hard disk power, and take
it up to 19W, you lose about 15min of battery life.
(for intermittent drive access, if the machine is doing constant
drive access at full rate, then it may get more work done if the drive
is faster).

Make sure that the drive will physically fit.
Height is the important factor here.
