FC0-U71 Infrastructure Practice Question
A user wants to upgrade their laptop's storage to improve boot times and file transfer speeds. The laptop has an available M.2 slot. Which type of drive should the user choose?
⚠ Common exam trap
FC0-U71 often tests whether candidates conflate the M.2 form factor with NVMe — the trap is picking 'SATA M.2 SSD' because it fits the slot, ignoring that the question asks for maximum speed.
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
An NVMe M.2 SSD uses the PCIe bus and the NVMe protocol, delivering far higher sequential and random I/O than SATA-based drives — directly improving boot times and file transfer speeds. Since the laptop has an M.2 slot, an NVMe M.2 drive is the correct high-performance choice. It is also the form factor that maximizes the slot's potential.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
2.5-inch SATA HDD
Why it's wrong here
A 2.5-inch SATA HDD is a spinning magnetic disk limited to roughly 150 MB/s and cannot seat in an M.2 slot at all. Tempting because it is cheap per gigabyte, and would be correct for low-cost archival storage in a 2.5-inch bay.
- ✗
SATA M.2 SSD
Why it's wrong here
SATA M.2 SSDs cap at roughly 550 MB/s because they tunnel the SATA AHCI protocol, whereas an NVMe M.2 drive uses PCIe lanes for far higher throughput. Tempting because it fits the M.2 slot, and would suit a board whose M.2 slot is SATA-only.
- ✓
NVMe M.2 SSD
Why this is correct
NVMe M.2 SSDs communicate over PCIe lanes rather than the SATA bus, delivering far higher throughput and lower latency. Fitting the available M.2 slot, this satisfies the requirement for faster boot times and file transfers.
- ✗
External USB 3.0 HDD
Why it's wrong here
An external USB 3.0 HDD spins at 5400–7200 rpm and traverses the USB bus, so boot and transfer speeds stay far below an internal NVMe drive. Tempting for extra capacity, and would be correct for bulk backup storage rather than a boot device.

Same concept, more angles
7 more ways this is tested on FC0-U71
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. 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?
easy- ✓ A.NVMe M.2 SSD
- B.SATA HDD
- C.SATA SSD
- D.External USB 3.0 HDD
Why A: 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.
Variation 2. A user is selecting a storage device for a new computer and wants fast boot times and durability. Which TWO storage technologies should the user consider? (Select TWO.)
easy- A.Optical drive
- ✓ B.NVMe SSD
- C.HDD (Hard Disk Drive)
- D.Magnetic tape
- ✓ E.SSD (Solid State Drive)
Why B: NVMe SSDs and SATA SSDs both use flash memory, delivering fast boot times and no moving parts for durability. NVMe drives connect via PCIe and offer significantly higher throughput and lower latency than SATA SSDs, while standard SSDs remain a cost-effective, durable option. Together they satisfy the 'fast boot times and durability' requirement.
Variation 3. A user's laptop has a SATA SSD, and they want to upgrade to a faster storage solution. Which interface technology would provide the most significant performance improvement?
medium- A.Hybrid drive (SSHD)
- ✓ B.NVMe M.2
- C.External USB 3.0 SSD
- D.SATA M.2
Why B: NVMe M.2 provides the most significant performance improvement because it communicates over PCIe lanes rather than the SATA bus, bypassing the AHCI controller and its ~600 MB/s ceiling. NVMe drives routinely exceed 3,000 MB/s and support deep parallel command queues (up to 64K queues with 64K commands each), dramatically reducing latency.
Variation 4. 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?
easy- A.SATA
- B.PATA
- ✓ C.NVMe M.2
- D.USB 2.0
Why C: 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.
Variation 5. A user wants to upgrade their desktop computer to faster storage. Which of the following storage interfaces provides the highest data transfer speeds?
easy- ✓ A.NVMe M.2
- B.USB 2.0 flash drive
- C.SATA SSD
- D.External HDD
Why A: NVMe M.2 drives connect directly to the PCIe bus, bypassing the SATA/AHCI bottleneck entirely. NVMe was designed for flash storage with deep parallel command queues (up to 64K queues with 64K commands each), delivering sequential reads in the 3,000–7,000+ MB/s range on PCIe 3.0/4.0. This makes it the fastest storage interface among the options by a wide margin.
Variation 6. Which of the following storage interfaces provides the fastest data transfer speeds?
easy- A.USB 3.0
- B.SATA
- ✓ C.NVMe M.2
- D.Ethernet
Why C: NVMe M.2 is correct because it uses the PCIe bus directly, bypassing the SATA interface and AHCI protocol, which allows much higher throughput and lower latency. Typical NVMe drives reach sequential read speeds of 3,500 MB/s or more on PCIe 3.0 and over 7,000 MB/s on PCIe 4.0, far exceeding SATA III's 600 MB/s ceiling. This makes NVMe M.2 the fastest storage interface among the options for direct-attached storage.
Variation 7. A user wants to upgrade their desktop's storage from a traditional hard drive to a faster drive that connects directly to the motherboard without cables. Which storage interface should they choose?
medium- A.External USB drive
- B.SATA SSD
- C.SATA hard drive
- ✓ D.NVMe M.2
Why D: NVMe M.2 drives plug directly into an M.2 slot on the motherboard, requiring no data or power cables, and use the PCIe bus for far higher throughput than SATA. This matches the user's requirement of a fast drive that connects directly to the motherboard without cables. M.2 NVMe is the standard choice for modern desktop storage upgrades where cable-free installation and maximum speed are priorities.
