Storage Devices and RAID Configurations Flashcards
| 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 |
