Build yours this weekend. You’ll thank yourself when disaster strikes.
| RAID Level | How it works | Tolerates | Use case | |------------|--------------|-----------|----------| | RAID 1 | Mirroring | 1 drive failure | OS, small critical data | | RAID 5 | Striping + parity | 1 drive failure | General storage (3+ drives) | | RAID 6 | Striping + dual parity | 2 drive failures | Large media, high safety | | RAID 10 | Mirrored stripes | 1–2 drives | Databases, high I/O | create redundant data recovery mechanism
Below is a using three complementary layers. Layer 1: RAID (Real-time Redundancy) Protects against immediate drive failure without downtime. Build yours this weekend
