After writing 50 GB files to a number of hard drives in episode 2, I decided to have a look how the drives would perform after randomly deleting some about 2.5 TB of 50 GB files and then fill up the empty space again. Before running the tests my expectation was that the outer parts of the disk would be filled first, as write speeds are fastest there and write speeds would gradually reduce over time. The graph at the top of this post that plots the write data rate in MB/s over time shows something else, however.
