What is characteristic of RAID Level 3?

RAID Level 3 is designed to improve performance by using byte-level striping and includes the use of parity for fault tolerance. In this configuration, data is divided into bytes that are distributed across multiple drives, which allows for the high-speed access and redundancy that RAID levels provide. The parity information, which is calculated from the data across all drives, allows the system to recover data in the event of a disk failure.

This method of byte-level striping means that RAID Level 3 can take full advantage of multiple disks, as it can read and write data concurrently across all drives, enhancing overall performance. If one drive fails, the data can be rebuilt using the parity stored on the remaining drives, ensuring data integrity and availability.

This characteristic distinguishes RAID Level 3 from the other options, which describe different RAID behaviors, such as mirroring data, only writing data to a single disk, or not duplicating data across drives. These features do not apply to the byte-level striping and parity approach utilized in RAID Level 3.
