Two things to help writing your thesis faster:
The first. Plan your thesis structure outline etc. Know what you want to achieve and when you want to achieve it by. Know the questions you want to ask and answer in your thesis. Know where your data are.
The second thing is to start writing as early as you possibly can. Even if you're in year one I'd still suggest you start writing as soon as you can. Not all of the writing you will use in your thesis, but it will definitely help with your planning and your thinking; not to mention the structure of your argument.
So good luck getting your thesis written!
