Data restore after failed SAS controller Dell PowerEdge 840

Last Modified: 2016-11-23
Server has a failed RAID drive and the controller is not working properly as I'm getting I/O error messages in Windows Event Log and can't copy files into external USB, it also gives I/O errors and stops.  

We want to transfer data into the new server but are not able to at this point.

Is it possible to plug the hard drive to a regular computer to access the data using a SAS controller?

For example: install one of these SAS controllers on a Dell Optiplex

I'm just not sure if that gets installed if the computer tries to boot from it instead of the SATA drives onboard?

My other option is to get a used SAS5i/r controller to replace the defective one, but since I have a failed drive I'm not sure if the controller will allow to initialize the array for boot?
