3WARE 8506-4

I have 3WARE 8506-4 RAID controller and 4 SATA HDDs attached to it.
Everything works OK, but whenever I benchmark the new RAID drive (/dev/sda), the result is only around 62MB/s!
Doesn't matter if I set up RAID0 or RAID10, doesn't matter if I change strip size, disks have the same speed as if there was only one.

I don't know what else to try and would really appretiate any help from you guys.

Thanks in advance!
