Yes, the second one is using a StringBuild to build a very large string, then calling ToString on it to create a new String object, then your writing the new string out to a file.

The two pieces of code are no doing the same thing. Your appending some data to a StringBuild, then creating a new String of all the data, appending some more data, creating a new String of all that data, ..., .... The string is getting bigger and bigger and bigger and your recreating the beginning part of the string over and over again with each pass. Your writing out something akin to:
1111 11112222 111122223333 1111222233334444 11112222333344445555 111122223333444455556666

whereas the first little snippet is doing this:
1111
2222
3333
4444
5555
6666
