- A
The drive will not be recognized
Why wrong: SATA III drives are backward compatible with SATA II and will be recognized.
- B
The drive will operate at SATA III speeds
Why wrong: The backplane limits the speed to SATA II (3 Gbps), so the drive cannot run at SATA III speeds.
- C
The drive will operate at SATA II speeds
The drive will negotiate down to SATA II speed due to the backplane's limitation.
- D
The drive will be damaged
Why wrong: SATA interfaces are designed for backward compatibility, so no damage will occur.
Question 825 of 1,020
SATA III Backward Compatibility: Operating at SATA II Speeds
This 220-1201 practice question tests your understanding of connectors. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A technician is replacing a failed hard drive in a server. The new drive has a SATA III connector, but the server's backplane only supports SATA II. What will be the result of using this drive?
Quick Answer
The correct answer is that the drive will operate at SATA II speeds. This happens because SATA III is fully backward compatible with SATA II, meaning the interface automatically negotiates down to the highest common speed supported by both the drive and the controller. Since the server’s backplane only supports SATA II’s 3 Gbps limit, the new SATA III drive will run at that slower rate without any damage or errors—it simply cannot achieve its full 6 Gbps potential. On the CompTIA A+ Core 1 220-1201 exam, this scenario tests your understanding of SATA generation compatibility and performance limitations, often appearing as a trap where candidates assume the drive will fail or run at half speed. A common memory tip: think of SATA III as a highway with a 6 Gbps speed limit, but if the road (the backplane) only allows 3 Gbps, you’re stuck in the slow lane—the car still runs fine, just slower.
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
✓
The drive will operate at SATA II speeds
SATA III is backward compatible with SATA II, so the drive will work but at SATA II speeds (3 Gbps). This tests knowledge of SATA generation compatibility and performance limitations. The drive will not be damaged but will not achieve its maximum speed.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The drive will not be recognized
Why it's wrong here
SATA III drives are backward compatible with SATA II and will be recognized.
- ✗
The drive will operate at SATA III speeds
Why it's wrong here
The backplane limits the speed to SATA II (3 Gbps), so the drive cannot run at SATA III speeds.
- ✓
The drive will operate at SATA II speeds
Why this is correct
The drive will negotiate down to SATA II speed due to the backplane's limitation.

Why it's wrong here
SATA interfaces are designed for backward compatibility, so no damage will occur.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 220-1201 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
