Why each option
The technician needs a RAID level that offers high speed and low cost without concern for fault tolerance for a video editing system.
RAID 0, also known as striping, distributes data across multiple drives, significantly enhancing read and write performance by allowing parallel disk operations. It utilizes 100% of the disk capacity, making it cost-effective per terabyte, while achieving the highest speed among basic RAID levels, albeit without providing any fault tolerance.
RAID 1 (mirroring) prioritizes fault tolerance by duplicating data, which halves usable storage and does not primarily focus on speed or cost efficiency.
RAID 5 (striping with parity) offers fault tolerance and good performance but involves parity calculations that can reduce write speed compared to RAID 0 and has capacity overhead.
RAID 10 (striped mirrors) provides both high performance and fault tolerance but is the most expensive option due to its 50% capacity overhead.
