PROXMOX and IO Speed ? low

Hi,
I am receiving following scores on serverbear for IO. Disk is RAID 10 - SEAGATE 15K SAS -600GB x 4.
I am not sure if this is okay ? I feel this is way low for what it should be.

Try to give us less information about your specific set up, then perhaps we can help, please be as vague as possible.
Thanks.
Morning,
Having read my comment the next day I decided I was a bit harsh.
Please confirm your write cache settings, that will probably be a start.
Have you used the search form in the Proxmox VE forum ?
There is a thread about your card http://forum.proxmox.com/threads/9552-RAID-Controller-LSI-MegaRAID-9261-8i?highlight=lsi+mega+raid
@syscentral : Very well said - No drivers for more than Deb 5.0, what to do now?
@AnthonySmith : this doesnt has a cache.
Ask LSI if they can help for example. The support team from lsi is very helpfull.
They've provided me with a firmware hack/upgrade, magicly making my HBA into a full fledged RAID
@Raymii : HBA ??
