Very slow HP 8 Internal Port SAS HBA with RAID 0, 1 on Hot Plug SAS/SATA Models (LSI SAS1068 - mpt)

Hi list,

I'm having problems with the raid controller of HP ProLiant DL140 G3 
Server and RELENG_7

I have 2x 500GB SATA HDDs configured as mirror, but the write speed is 
very slow ~7MB/s.

I guess that there is no battery for the raid controller and the write 
cache is off, but 7MB/s ..
Also there is no way to see the status of the raid from FreeBSD ?

Any ideas how to improve this?

I'm running bonnie++ to see the real performance, but result will be
