Scores look fine to me. You filled the drive already, so it's not testing the fastest portions of your disk.
You can also try HDTune on the disk in safe-mode (if that works?) to see what raw speeds you get on the outer tracks on your HDD. The outer tracks give you the fastest throughput, while the inner tracks would have roughly 50% of the performance of the outer tracks. Server-drives short-stroked by design have lower degradation; thus the inner tracks are still 70% of the outer tracks, for example.
