220-801 Question #525: Real Exam Question with Answer & Explanation

The correct answer is B: Two 500 GB SATA2 hard drives in a hardware RAID 0. Video editing requires both maximum read/write speed and large capacity. Hardware RAID 0 (B) stripes data across both drives simultaneously, effectively doubling throughput and combining their capacity (2 × 500 GB = 1 TB) - ideal for large video files. Hardware RAID 0 offloads th

Question

Video editing workstations require the fastest hard drive access times with large storage capacity. Which of the following hard disk setups would be MOST ideal for the described computer?

Options

ATwo 500 GB SATA2 hard drives used in a JBOD array
BTwo 500 GB SATA2 hard drives in a hardware RAID 0
CTwo 500 GB SATA2 hard drives in a hardware RAID 1
DTwo 500 GB SATA2 hard drives in a software RAID 0

Explanation

Video editing requires both maximum read/write speed and large capacity. Hardware RAID 0 (B) stripes data across both drives simultaneously, effectively doubling throughput and combining their capacity (2 × 500 GB = 1 TB) - ideal for large video files. Hardware RAID 0 offloads the work to a dedicated controller, minimizing CPU overhead. JBOD (A) offers no performance benefit; drives are used sequentially. RAID 1 (C) mirrors data for redundancy but does not increase speed or total usable capacity. Software RAID 0 (D) achieves striping but consumes CPU cycles, reducing overall performance compared to hardware RAID.
