Exam D-ISM-FN-23 Topic 5 Question 72 Discussion

Actual exam question for EMC's D-ISM-FN-23 exam
Question #: 72
Topic #: 5
What is the total usable data storage capacity in this scenario:
a RAID 6 array with four 250 GB disks

Suggested Answer: A Vote an answer

RAID 6 uses two parity blocks for data protection, allowing it to withstand the failure of two drives. In a RAID 6 array with four 250 GB disks, the usable capacity is calculated by subtracting the space used for parity. With four disks, two are used for parity, leaving the capacity of two disks for data storage. Therefore, the total usable data storage capacity is 2 * 250 GB = 500 GB.
