Choosing Wisely: SanDisk Pro G-RAID MIRROR Drive

Maniacal about making backup copies of photos and video footage like I am? Then this baby is for you. When set to RAID 1, the SanDisk Professional G-RAID MIRROR drive automatically duplicates data onto a second built-in drive as it's stored to provide worry-free data redundancy.

Backup copies of data, images and video files are like vitamins: we know how important they are, but sometimes we forget. Oh, you might sidestep disaster for a while, but sooner or later fate catches up with you. The SanDisk Professional G-RAID MIRROR external RAID drive takes human frailty out of the equation and automatically keeps two copies of everything you save to it. The benefits are obvious. In the unlikely event that your primary storage drive fails, you have a backup immediately at hand. Score that Technology 1, Regret 0.

RAID is an acronym for "Redundant Array of Independent Disks," which is self-explanatory. RAID drives can be configured in various ways, each identified by a number after the word RAID. For example, RAID 1 is often called "mirroring" because it saves two identical copies of all data as described here. The SanDisk Professional G-RAID MIRROR external drive comes out of the box set up as a RAID 1.


The SanDisk Professional G-RAID MIRROR can also be arranged as a RAID 0, where instead of being saved as two distinct and identical copies, data is divided and spread across multiple drives. This is called "striping" and the primary benefit is increased data transfer speed (but with no redundancy). This SanDisk drive can likewise be setup in the JBOD configuration. JBOD stands for "Just a Bunch of Disks." In fact, with the SanDisk G-RAID Mirror drive, users can change the RAID mode setting from default RAID 1 to RAID 0 or JBOD just by flipping a switch, i.e., without  the need to download an app or install special software.
