Which of the following features describes RAID 1+0? (Select two)

RAID 1+0, also known as RAID 10, is a hybrid configuration that combines the features of RAID 1 (mirroring) and RAID 0 (striping). One of the key characteristics of RAID 1+0 is that it provides redundancy through mirroring while also offering improved performance through striping.

With this setup, half of the total storage capacity is effectively used for fault tolerance because each piece of data is mirrored on a separate disk. This means that while the overall storage may be larger, only about 50% of that capacity is available for actual data storage, as the other half serves to duplicate that data for reliability, thus directly supporting the statement regarding capacity dedicated to fault protection.

Additionally, the nature of RAID 10 involves striping data across multiple disks, which enhances the read and write performance. Striping means that data is split into blocks and distributed evenly across the paired drives, allowing simultaneous access to multiple disks during read or write operations, thereby improving speed. This ensures that users can benefit from higher performance levels compared to configurations that do not have striping.

The other features mentioned in the choices pertain to different RAID configurations or do not accurately represent the RAID 1+0 structure. For instance,
