CrystalDiskMark reads/writes data within your partition. If you added a lot of data to your drive since your last test, what you're seeing is normal. The beginning of your drive is always the fastest, and performance will get slower and slower as you move towards the end of the drive. The WDBlack has a max speed of ~108MB/s at the beginning of the drive, a min speed of ~52MB/s at the end of the drive, and an average read speed of ~86MB/s.
