You have been asked to design a high performing and highly redundant storage array with a minimum of 64 TB of usable space for files. 4 TB hard drives cost $200, 6 TB hard drives cost $250, 8 TB hard drives cost $300, and 10 TB hard drives cost $350. Explain which type of RAID you would choose and the quantity and types of drives you would use for your solution. Weigh the cost vs redundancy in your solution.

Check the explanation

Explanation:

Number of 4 TB hard drive need = 32/4 = 8 and cost = 200*8 = $1600

Number of 6 TB hard drive need = max(32/6) = 6 and cost = 250*6 = $1500

Number of 8 TB hard drive need = 32/8 = 4 and cost = 300*4 = $1200

Number of 10 TB hard drive need = 32/10 = 4 and cost = 350*4 = $1400

Hence using 4 hard drive of 8 TB will minimize the cost.
