Very slow volume RAID1

[LWiks]

Hi,

I have an HP Z800 and for the OS I have created an RAID1 volume using two Hitachi 320 GB hard disks. However, the performance I get is terrible. What is wrong? Any ideas?

Thanks,

Lars

and the S drive which should be similar but is much faster

These are the components

Hi Nortwind,

I understand you are experiencing performance issues with the HP Z800 Workstation on RAID 1 volume and Windows® 7. Thank you for reporting this matter at Intel communities.

After checking the specifications for this http://www.hp.com/canada/products/landing/workstations/files/13278_na.pdf HP Z800 Workstation computer and I noticed that it comes with an Intel® 5520 server chipset.Please bear in mind that this type of controller is handled by the computer manufacturer since the chipset can be modified as part of their integration configuration.
