| JBOD | The use of one or more drives not in a RAID configuration but managed as separate logical volumes. |
| Spanning | Combination of drives in a linear fashion to create one large logical volume. |
| RAID 0 | Data is striped across multiple hard drives, enabling accelerated reading and recording of data by combining the work of two or more drives to increase performance.
However, If one drive fails, all of your data will be lost. |
| RAID 1 (default) | Two instantaneous copies of the data are recorded on separate hard drives so if one of them fails, other(s) continue to read/write data until the faulty hard drive is replaced. |
| RAID 5 | Offers superior performance and protection by striping data across 3 or more drives and dedicating a quarter of each drive to fault tolerance. If one of the drives fails, the other(s) continue to read/write data until the faulty hard drive is replaced.
This option is only available on 4-bay My Cloud devices. |
| RAID 10 | RAID protocol in which data is written in stripes across primary disks that have been mirrored to the secondary disks. If one of the drives fails, the other(s) continue to read/ write data until the faulty hard drive is replaced.
