Using two 7200RPM drives with Intel's Thunderbolt 2 technology and a hot-swappable hardware RAID controller, WD was able to provide fast and large storage for videos, photos and audio files. Back in the days when disk drives were slow and bulky and owning a high-speed and high-capacity drive would require an arm and leg (sometimes even a kidney), some people resorted to setting up multiple drives in RAID configuration. If you don’t know what RAID is or you just want to have better understanding of the various types of commonly-used RAID setups, then this post is for you. To kick thing off, let’s define what RAID is. Depending on who you’re talking to, RAID can either stand for Redundant Array of Inexpensive Disk or Redundant Array of Independent Disk – any of the two is ok though. In a nutshell, RAID is the term used to describe the method of combining multiple drives to either achieve better performance (increased read and write speeds), or create a fail-safe if something goes wrong with one of the drives. Now that we have the basics squared up, let’s check out the different types of commonly-used RAID configurations and how these will increase the reliability and/or performance of your disk drives.
