Step 1:Let me solve this step-by-step with a clear performance analysis:
Step 2:: Understand Storage Performance Metrics
- Performance depends on:
Step 3:
Access speed
Step 4:
Data transfer rate
Step 5:
Latency
Step 6:
Technology type
Step 7:: Analyze Each Option's Performance Characteristics
- A. 25 GB HDD: - Slowest technology - Mechanical moving parts - Typical speeds: 80 - 160 MB/s - High latency - B. 25 GB PCI-E Video Card: - Designed for graphics processing - Not primary storage device - Not suitable for general storage - C. 25 GB DDR^4 RAM: - Extremely fast access - Volatile memory (loses data when powered off) - Speeds: 17 - 25 GB/s - Primarily for active system memory - D. 125 GB USB 3.0: - Portable storage - Speeds: 5 - 10 GB/s - External storage solution - E. 25 GB SSD: - Fastest non-volatile storage - No moving parts - Speeds: 500 - 3500 MB/s - Low latency - Reliable storage
Step 8:: Performance Ranking
Step 9:
DDR^4 RAM (fastest but not persistent)
Step 10:
SSD (fastest persistent storage)
Step 11:
USB 3.0
Step 12:
HDD
Step 13:
PCI-E Video Card (not storage)
Final Answer
Option C (25 GB DDR^4 RAM) offers highest raw performance, but Option E (25 GB SSD) provides best practical storage performance with fast access and data persistence.
