Which of the following statements about RAID striping is completely incorrect? A) A stripe consists of one or more consecutive sectors on a disk, and multiple stripes form a strip. B) Striping evenly distributes I/O loads across multiple physical disks. C) Striping technology segments logically-sequential data into multiple data blocks and stores them on different disks. D) Striping enables a RAID group to provide faster speed than a single disk.
Understand the Problem
The question is asking us to identify the incorrect statement about RAID striping. We need to understand the basic principles of RAID striping to determine which statement is factually wrong.
Answer
Option A is incorrect. Multiple stripes form a stripe, not the other way around.
The statement that is completely incorrect about RAID striping is: A) A stripe consists of one or more consecutive sectors on a disk, and multiple stripes form a strip. The correct terminology is that multiple stripes form a stripe.
Answer for screen readers
The statement that is completely incorrect about RAID striping is: A) A stripe consists of one or more consecutive sectors on a disk, and multiple stripes form a strip. The correct terminology is that multiple stripes form a stripe.
More Information
RAID striping is a technique that segments logically-sequential data into multiple blocks and writes these blocks across multiple disks. This improves performance by distributing I/O loads.
Tips
It's easy to get confused with the terminology. Remember a 'stripe' is the complete row of segments across all disks.
