I wish to create a RAID 1 coupling between two HDDs &#8212; for storage purposes only (my OS is on an SSD) &#8212; but I don&#8217;t know which is the best route to take.My motherboard (Z77 chipset) comes with Intel Firmware RAID, but since I only wish to use my RAID for storage, I wondered if I might be better to use Windows 8 Disk Mirroring?Can anyone advise which is better?

RAID is done through a controller in the enclosure &#8211; I&#8217;ve never seen each of the drives separately.I recently reinstalled Windows from scratch and finally decided to run semi-regular backups. For that purpose, I imaged the pristine install and saved the VHD on the external drive. I then moved it to a different folder on the drive to make sure no backup software overwrites it.<\/li>\n<li><img decoding=\"async\" src=\"http:\/\/www.gravatar.com\/avatar\/86c21137605db31cf28da9075a87a5c3?s=32&amp;d=identicon&amp;r=PG\" \/><br \/>\nAidiakapi<br \/>\nnas raid-1<br \/>\nI hope this is the right place to post this question.I&#8217;ve been searching for a while, to find an answer to this.
