| Front | Back |
| External HDD | Cost-effective and portable but slower than SSD options |
| External SSD | Portable with high-speed performance suitable for large file transfers |
| HDD | Traditional spinning disk storage that is slower but more cost-effective for large capacities |
| NAS | Network-attached storage for centralized file sharing and backups |
| NVMe | High-speed storage interface designed for SSDs using PCIe lanes |
| RAID 0 | Striping across multiple drives for performance but lacks redundancy |
| RAID 1 | Mirroring data across drives for redundancy but halves available capacity |
| RAID 10 | Combines striping and mirroring for both performance and redundancy, requiring an even number of drives |
| RAID 5 | Stripes data with distributed parity for performance and redundancy but requires at least three drives |
| RAID 6 | Similar to RAID 5 but uses double parity for higher fault tolerance, requiring at least four drives |
| SAN | Storage area network for high-performance enterprise data access |
| SAS | High-performance storage interface for enterprise environments |
| SATA | Common storage interface for HDDs and SSDs with slower speeds than NVMe |
| SSD | Solid-state storage with faster speeds and no moving parts compared to HDD |
About the Flashcards
Flashcards for the CompTIA A+ exam guide you through essential storage technologies tested on the exam. Quickly compare HDDs, SSDs, and NVMe drives, understand where speed, capacity, and cost intersect, and recognize the best use cases for each device.
These cards also break down SATA, SAS, and PCIe interfaces, then move into RAID 0, 1, 5, 6, and 10 to clarify how striping, mirroring, and parity protect data or boost performance. Round out your study with portable external drives and enterprise network solutions like NAS and SAN, ensuring you can recommend the right architecture in any scenario.
Topics covered in this flashcard deck:
- HDD vs SSD
- NVMe, SATA, SAS
- RAID levels 0-6, 10
- External storage options
- NAS and SAN basics
