Compare RAID Configurations
| Configuration | Usable Space | Hardware Cost | 3-Year TCO | Cost per TB | Best For |
|---|---|---|---|---|---|
| RAID 0 (4x 8TB) No Redundancy | 32 TB | €756 | €1,017 | €31.78 | Speed |
| RAID 1 (4x 8TB) ★ Current Selection | 16 TB | €756 | €1,017 | €63.56 | Balance |
| RAID 5 (4x 8TB) Single Parity | 24 TB | €756 | €1,017 | €42.38 | Efficiency |
| RAID 6 (4x 8TB) Double Parity | 16 TB | €756 | €1,017 | €63.56 | Safety |
Pro Tip
RAID 5 offers the best cost per TB, but requires minimum 3 disks. RAID 1 is simpler and faster for small arrays.
