Writing data to file

In what way should you write data to a file to get the Best performance.

Lets say I have a method called

void writeData(String line){

}

If I feed the writeData method with lines, should I use a BufferedWriter wrapped around a FileWriter.

Should I use Streams instead?

PrintWriter seems to be working quite bad.

After accessing 61 files(no matter size) my BufferedWriter takes a large pause.
