You work as an IT support technician for a boss who believes you are really bright and can solve just about any problems he throws at you.  Folks in the company have compalined one time too many that the file server downtime is just killing them, so he asks you to solve the problem. He wants you to figure out what hardware is needed to implement hardware RAID for fault tolerance.

You check the file server's configuration and discover it has a single hard drive using a SATA connection with Windows Server 2012 installed.  There are four empty bays in the computer case and four extra SATA power cords.  You also discover an empty PCIe x4 slot on the motherboard.  UEFI/BIOS setup does not offer the option to configure RAID, but you think the slot might accomodate a RAID controller. 

Complete the investigation and do the following:

1. Decide what hardware you must purchase and print webpages showing the products and their cost.

2. What levels of RAID does the RAID controller card support?  Which RAID level is best to use?  Print any important information in the RAID controller documentation that supports your decisions.

3. What is the total hardware cost of implementing RAID?  Estimate how much time you think it will take for you to install the devices and test the setup.
