APAC 10x 8TB RAID 10 NAS Calculator

Estimate usable TB, parity, and fault tolerance for APAC homelab buyers using 10x 8TB in RAID 10.

Capacity Snapshot

Raw Capacity

80.00 TB

Usable Capacity

36.00 TB

Fault Tolerance

1 drive per mirror pair*

Efficiency

50.0%

Excellent random I/O and rebuild behavior; capacity is typically 50% of raw. This scenario applies a 10% filesystem reserve.

APAC Buyer Context

APAC builders frequently compare availability windows and procurement variance, which makes robust fallback capacity and staged scaling useful in practice.

• Plan a spare strategy alongside RAID level selection.
• Validate that chosen parity can tolerate delayed disk replacement windows.

Brand / Region Glossary

Procurement Variance

Regional differences in disk availability and replacement lead times.

Spare Strategy

Policy of keeping spare disks available to reduce recovery delay risk.

FAQ

Can this calculator replace real-world benchmark and rebuild testing?

No. Use this page for pre-purchase sizing, then validate with workload benchmarks, SMART health policy, and a tested restore plan.

How much real-world usable storage does 10x 8TB RAID 10 provide?

For APAC homelab buyers, this NAS planning scenario estimates 36.00 TB usable after a 10% reserve from 80.00 TB raw.

Is RAID 10 still worth deploying with 8TB drives?

It can be practical, but larger drives increase rebuild windows. Validate parity choice and backup policy before committing to the final layout.

Why include a 10% reserve when planning NAS storage headroom?

Keeping free space improves filesystem behavior for snapshots, metadata, and write performance. Full arrays often perform worse and rebuild more slowly.
