FC0-U71 Infrastructure Practice Question
A user wants to upgrade their desktop computer's storage for faster boot times. Which of the following storage interfaces would provide the fastest performance?
⚠ Common exam trap
Many candidates confuse form factor with interface — candidates may assume any M.2 drive is NVMe, but M.2 slots can also run SATA, so the correct answer hinges on the NVMe protocol, not the physical shape.
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 SSD
NVMe M.2 SSDs communicate directly over the PCIe bus using the NVMe protocol, bypassing the legacy SATA/AHCI stack and delivering sequential read speeds of 3,000–7,000+ MB/s. This dramatically reduces boot times compared to SATA-based storage, which is capped at roughly 550 MB/s. For a desktop upgrade focused on faster boot, NVMe M.2 is the highest-performance interface listed.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
NVMe M.2 SSD
Why this is correct
NVMe M.2 SSDs communicate directly over the PCIe bus rather than through the SATA controller, delivering far higher throughput and lower latency. This directly satisfies the stem's requirement for faster boot times, since the operating system's random read operations benefit most from reduced access latency.
- ✗
SATA HDD
Why it's wrong here
SATA HDDs use spinning magnetic platters and typically deliver around 100-200 MB/s, far slower than NVMe SSDs, so boot times would not improve. SATA HDDs remain a valid choice for bulk, low-cost archival storage where capacity matters more than speed.
- ✗
SATA SSD
Why it's wrong here
SATA III caps at roughly 600 MB/s, so it cannot match the throughput of an NVMe drive on the PCIe bus. It is tempting because SATA SSDs still beat spinning disks and suit older motherboards lacking an M.2 slot, where SATA is the only realistic upgrade path.
- ✗
External USB 3.0 HDD
Why it's wrong here
USB 3.0 is an external serial interface with far lower throughput and higher latency than internal NVMe, so boot times barely improve. NVMe over PCIe is the correct choice for fastest boot performance; external USB suits portable backup storage instead.
