SG0-001 · Question #569
An administrator needs to increase performance of the current storage array. All of the bays are full so the administrator needs to replace the current 450GB 10k FC drives without decreasing capacity.
The correct answer is D. 450GB 15k FC drives. To increase storage performance while maintaining existing capacity, the administrator should replace the current 450GB 10k FC drives with 450GB 15k FC drives.

Why each option
To increase storage performance while maintaining existing capacity, the administrator should replace the current 450GB 10k FC drives with 450GB 15k FC drives.
300GB drives decrease capacity, and SATA drives generally offer lower performance than FC drives, failing both requirements.
300GB drives decrease the overall storage capacity of the array, which contradicts the goal of not decreasing capacity.
7.2k RPM drives have significantly lower performance compared to 10k RPM or 15k RPM drives, and SATA is typically slower than FC for high-performance use cases.
Replacing 10k RPM Fibre Channel (FC) drives with 15k RPM FC drives of the same 450GB capacity provides a significant performance boost due to the faster rotational speed, ensuring higher I/O operations per second (IOPS) without reducing storage space.
