The correct answer is D. 750GB 7200rpm SAS. With four drive bays and a 2.2TB storage requirement and no SAN available, only four 750GB drives provide enough total raw capacity to meet the requirement.
Question
An administrator is selecting hardware for a new application. There is no SAN storage available. The application requires 2.2TB of storage space, and the server has four available drive bays. Which of the following drive types will BEST meet these requirements?
Options
- A250GB 15000rpm SAS
- B500GB 10000rpm SAS
- C512GB SSD
- D750GB 7200rpm SAS

Why each option
With four drive bays and a 2.2TB storage requirement and no SAN available, only four 750GB drives provide enough total raw capacity to meet the requirement.
Four 250GB SAS drives yield only 1TB of total raw capacity, which falls far short of the required 2.2TB.
Four 500GB SAS drives yield only 2TB of total raw capacity, which does not meet the 2.2TB minimum requirement.
Four 512GB SSDs yield approximately 2.048TB of total raw capacity, which also fails to meet the 2.2TB requirement, and SSDs carry a higher cost-per-gigabyte penalty that makes them a poor fit for bulk capacity needs.
Four 750GB 7200rpm SAS drives yield 3TB of total raw capacity, which is the only configuration among the choices that exceeds the required 2.2TB using exactly four drive bays. SAS drives at this capacity are a cost-effective choice for direct-attached storage when no SAN is available.
