My Promise R8 Raid was nearly full (18TB/19TB) and so it was really slow. Ok!

So i have deleted old Data and have now 6,18TB from 19TB free. But it is always very slow (WRITE: aprox. 80MB/s). READ is aprox 500MB/s and okay. 

Is there a possibilty to "defrag" this Raid?

Or is there another trick?
