PAS-C01 Migration Practice Question

Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
io2 Block Express
SAP HANA requires high IOPS and low latency, and io2 Block Express provides the highest performance for such requirements. Option A is wrong because sc1 is a cold HDD, which provides low IOPS and is not suitable for SAP HANA. Option B is wrong because st1 is throughput-optimized HDD, designed for large sequential workloads, not for high IOPS. Option C is wrong because gp3 is a general-purpose SSD; while it can provide up to 16,000 IOPS, io2 Block Express offers higher and more consistent IOPS and lower latency, making it the preferred choice for SAP HANA data volumes.
