Compare usable TB, parity, and failure tolerance between RAID 1 and RAID 5 for APAC homelab setups.
This page compares RAID 1 and RAID 5 on identical hardware assumptions to help homelab builders choose between capacity efficiency and fault tolerance.
| Drives | RAID 1 | RAID 5 | Delta |
|---|---|---|---|
| 4x 8TB | 7.20 TB | 21.60 TB | -14.40 TB |
| 6x 8TB | 7.20 TB | 36.00 TB | -28.80 TB |
| 8x 8TB | 7.20 TB | 50.40 TB | -43.20 TB |
| 10x 8TB | 7.20 TB | 64.80 TB | -57.60 TB |
| 12x 8TB | 7.20 TB | 79.20 TB | -72.00 TB |
APAC builders frequently compare availability windows and procurement variance, which makes robust fallback capacity and staged scaling useful in practice.
Regional differences in disk availability and replacement lead times.
Policy of keeping spare disks available to reduce recovery delay risk.
Yes. Similar usable TB does not imply similar failure tolerance or rebuild exposure. Capacity and resiliency should be evaluated together.
Choose based on your risk tolerance, rebuild window, and performance profile. Higher parity usually lowers capacity but improves resilience.
Rebuild behavior depends on array width, disk size, and workload pressure. This page focuses on capacity and tolerance; benchmark your actual platform before final choice.
The better option is the one that keeps acceptable usable capacity while preserving safety margins during future disk expansions.
