I wouldn't be surprised if that was a case of the hard drive itself dying. Usually when it nears the end of its product life, it tends to run slow like that.

It is abrupt, I know because I had mine drop suddenly without much warning.

Might I suggest DxTory? It is mainly for recording, but it also has a great benchmarker for testing the write speed of your computer. Ideally, you want either 90 or 100 at least.
