FC0-U71 Infrastructure Practice Question
A technician is selecting a storage interface for a new solid-state drive that offers the fastest data transfer speeds. Which interface should they choose?
⚠ Common exam trap
FC0-U71 often tests the confusion between form factor and protocol, tempting candidates to pick SATA because it is familiar, even though NVMe over PCIe is decisively faster.
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
✓
NVMe M.2
NVMe M.2 is the fastest storage interface listed because it uses the PCIe bus and the NVMe protocol, bypassing the older SATA/AHCI stack. NVMe drives deliver far higher IOPS and sequential throughput than SATA SSDs, often exceeding 3,000 MB/s versus SATA's ~550 MB/s ceiling. For a technician selecting the fastest SSD interface, NVMe M.2 is the correct choice.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
SATA
Why it's wrong here
SATA III caps at roughly 600 MB/s, which throttles NVMe-class SSDs that reach several GB/s over PCIe lanes. SATA remains a valid, cost-effective choice for budget 2.5-inch SSDs, but the stem asks for the fastest interface, which is NVMe.
- ✗
PATA
Why it's wrong here
PATA transfers data over a parallel ribbon cable with a 133 MB/s ceiling and is obsolete for modern SSDs, so it cannot deliver the fastest speeds. It is tempting because PATA was the standard desktop interface before SATA, making it the right answer only for legacy systems.
- ✓
NVMe M.2
Why this is correct
NVMe M.2 drives communicate directly over PCIe lanes rather than translating through the SATA or SAS command sets, removing the AHCI bottleneck. That native PCIe path delivers far higher queue depth and throughput, satisfying the fastest-transfer-speed constraint.
- ✗
USB 2.0
Why it's wrong here
USB 2.0 provides only 480 Mbps, far slower than any internal SSD interface, so it cannot satisfy the fastest-transfer requirement. It is tempting because USB is familiar and convenient for external drives, and USB 3.x or Thunderbolt would be reasonable for portable storage.
