CalDigit T4RAID Stands for: redundant array of independent disks. A RAID drive consists of 2 or more hard drives connected together which can either appear as one volume or mirror each other.

Common RAID settings are:

RAID 0 – data is striped across all disks giving fast read/write, ideal for video editing. The advantage is speed but if one drive fails in RAID 0 you will lose your data so some people use RAID 5.

RAID 5 – Data is spread across all disks but if one drive fails, your disk stays online. This is fast and redundant as it allows for up to one disk failure.

RAID 1 – One disk mirrors the data on to another disk. This is common for people who require a real-time secondary back up. If one drive fails you have a second backup copy.
