It could be the layout and not the keyboard. I was never able to learn QWERTY for some reason, but did learn Dvorak several years ago.
QWERTY is designed to slow you down, making you stretch to reach common keys. This was done to slow down typists who were fast and jammed early mechanical typewriters. (Like anything worth talking about, there is some debate about this.)
Dvorak is designed to minimize finger motion and repetitive use of the same fingers. More common letters are on the home row, and the most common are under stronger fingers. Vowels are on the left hand home row (A O E U I), common consonants on the right (D H T N S). This results in typed letters frequently alternating between hands. As an example, on a QWERTY keyboard, I can type my whole name (john johnson) and only use a left finger once.
Below are a couple of illustrations gleaned from the net. The first is a heat map of letter frequency and where the letters are on the keyboard. The second shows letter frequency by row. Naturally, one would want frequently used keys on the home row, and under the stronger fingers.
As for “hammering away,” this could be an indication that you are creating your own auditory and tactile feedback for the keyboard. This could be resolved with a more “clicky” keyboard, or turning on key click in the OS, if available.
