I am working on medical office in which they have a RAID 1 for the operating system (Windows Server 2008 R2) and a solo drive for the databases (2). The second drive does not have any RAID and I was going to to buy a new HDD to do another RAID 1, but I found out that the second HDD was a WD Green drive and should not be used for a RAID.
At this point I called WD and they confirmed that the Red ones are the ones for RAID but then I will have to buy 2 drives and move the data from the green one to one of the red one to make the RAID.
In the other hand I can use the server back-up tool to back-up the data but I don't think that's the best way to do it.
Is it better using Server Back-up or do the RAID Mirror?
