I have a Dell T605 PowerEdge server running SBS 2011 which came as standard with a Dell SAS6/IR Raid Controller card.
The server originally came with SBS 2003 but we upgraded to 2011 last year with minimal problems apart from the SAS6/IR card which Windows device manager has always had a problem with and couldn't get an appropriate driver that it was happy with.
That said the server has been running happily with 2 x 150GB OS drives raid 1 and 2 x 1.5TB data drives raid 1.
One of the data drives is now registering a fault so we are looking to replace them with new drives and as part of the upgrade we want to replace the SAS6/IR card with a newer model which is compatible with the existing hardware.
My question is what make and model of raid 1 card or better would you recommend?
