Best Buy customers often prefer the following products when searching for raid hard drive.

When it comes to protecting your data, you can never be too safe. And one of the best ways to do that is by using a RAID array. A RAID array uses two or more hard drives to create a single volume that's protected from failure. It's like having multiple copies of your data, and if one drive fails, the data is still there on another drive. Browse the top-ranked list of RAID hard drives below along with associated reviews and opinions.

    WD Purple drives are designed to meet the challenges of 24x7 video surveillance recording.

With WD Purple drives, you get reliable, surveillance-class storage that’s tested for compatibility in a wide range of security systems. Exclusive AllFrame technology helps reduce frame loss and improve overall video playback.
