after checking with a few c't hard disk reviews
(unfortunately I didn't find the exact model)
that looks like a reasonable performance for this kind of 2.5" drive.
They cite averages in the lower 20MB/s.

I have a T30 with the same model and get

/dev/hda1:
 Timing buffer-cache reads:   1572 MB in  2.00 seconds = 784.55 MB/sec
 Timing buffered disk reads:   60 MB in  3.10 seconds =  19.36 MB/sec
