Final answer:
The disk writing performance is improved by RAID 0, which stripes data across two or more drives, allowing for increased throughput but no redundancy. RAID 1, RAID 5, and RAID 10 also provide various levels of data protection and throughput improvements, but RAID 0 is specifically designed for performance enhancement in writing data.
Step-by-step explanation:
The disk writing performance improves when data is written across multiple drives because it allows for increased throughput and redundancy. The correct answer to your question is 1) RAID 0. RAID, which stands for Redundant Array of Independent Disks, has various levels, and each offers different performance improvements and data protection methods.
RAID 0 is known as striping and it writes data across two or more drives. This increases the disk writing performance because if you write to two drives at the same time, you can write twice as much data in the same amount of time compared to writing to a single drive. However, it's important to note that while RAID 0 improves performance, it does not offer redundancy; if one drive fails, all data in the array is lost.
RAID 1 is known as mirroring and it duplicates data across two drives for redundancy, but it does not improve write performance. RAID 5 provides data protection through striping with parity, allowing for the failure of one drive without data loss, and also offering better read performance, but not as much write performance improvement as RAID 0. RAID 10 combines the attributes of RAID 0 and RAID 1 by striping and mirroring data, providing improved performance and redundancy.
