Please can you assist.

I have attempted most of the popular BSD Variants such as NetBSD, Open
BSD, FreeBSD...
The only distrubution that seems to work on the is Dell SAS 6/iR Adapter
is FreeBSD 7.1
Firmware version & date : 9/29/2008

But the issue is that writing to disk is extremely slow...i.e. 14Mb per

If I install any other linux distribution, like CentOS, write speek is
the way it should be..it averages around 190Mb+ per second

I was hoping if it were at all possible for you to assist me in with a
later RAID Controller Driver for the SAS 6/iR Adapter

This is on a Dell PowerEdge R300 Server. 
BIOS Version 1.3.0
Running Raid 1

Kind Regards,
