sas - HP ProLiant ML350 G5 2.5 Sata slow write speed

im currently running Windows Server 2012 R2 with a HGST (Hitachi) z7k500-500 2.5 SATA drive.



I have a Smart Array E200i.



Read is about 140MB/S but write is only from 7-14MB/S.




I already updated the smart array firmware but same problem.



I checked the disk for bad sectors but everything ok.



The disk was completly new and is only 2 days old.



I dont have any comparsion (like crystaldiskmark) to 10k SAS drives but i remember that they're very very faster.
