Question: 1 / 1980

Which RAID configuration is known for striping data across multiple drives to improve performance?

RAID 1

RAID 0

The configuration that is known for striping data across multiple drives to enhance performance is RAID 0. In this setup, data is divided into blocks and each block is written to a separate disk drive, which allows for simultaneous read and write operations across all drives involved. This method significantly increases the speed of data access and overall performance compared to using a single disk.

In a RAID 0 array, there is no redundancy, meaning that if one drive fails, all data in the array is lost. This trade-off makes RAID 0 suitable for situations where performance is critical and data loss can be tolerated or is mitigated through other means, such as regular backups.

Other RAID configurations offer different advantages and methodologies. For instance, RAID 1 focuses on mirroring data for redundancy, ensuring that an exact copy exists on another drive for recovery purposes, while RAID 5 incorporates both striping and parity to provide fault tolerance, but with a trade-off in terms of write performance compared to RAID 0. RAID 2 uses Hamming code for error correction and is less commonly employed in practice, focusing more on data integrity than performance alone.
