You should be able to run a RAID 1 array if your MoBo chipset supports RAID 1 configurations.
I have a Win 7x64 Home Premium (OEM version) Desktop PC with an Asus MoBo. I was originally running a RAID 1 config but I disabled it for a couple of reasons:
The main reason I discontinued my RAID 1 setup was that although it does protect the PC against HDD failures and provides a real-time backup of HDD content, the mirror drive will also be affected by malicious intrusions.
I opted to go with a periodic Cloning (and Imaging less frequently) backup plan to backup the HDD in conjunction with my own script that backs up my often-edited/updated specific items on my PC.
The other reason I discontinued RAID was that I was having an intermittent Raid Array issue that was disabling the operation of the array and it was taking too much time to rebuild the array
That problem turned out to be an intermittent problem with one of my RAM sticks.
