The most reliable way to find answers for RAID Storage Calculator. Calculate usable space for RAID 0, 1, 5, 6, and 10 arrays. Designed for professionals...
Formula
const count = inputs.drives; const size = inputs.size; let usable = 0; if (inputs.type === 0) usable = count * size; else if (inputs.type === 1) usable = size; else if (inputs.type === 5) usable = (count - 1) * size; else if (inputs.type === 6) usable = (count - 2) * size; else if (inputs.type === 10) usable = (count * size) / 2; const total = count * size; const waste = total - usable; return { usable: usable, total: total, _chart: { type: 'pie', data: [{name: 'Usable Storage', value: usable}, {name: 'Parity/Mirror', value: waste}] } };Number of Drives

Use the result to compare providers, request quotes, or send the scenario to a specialist when the numbers matter.
RAID Storage Calculator estimates Usable Capacity (TB), Raw Capacity (TB), Chart from Number of Drives, Drive Size (TB), RAID Type. Use it to compare scenarios and understand which inputs drive the biggest changes. Results are directional estimates — verify with current, authoritative sources before making financial, legal, or health decisions.
Use this technology calculator to compare scenarios before committing money, time, or a provider conversation.
The estimate combines Number of Drives, Drive Size (TB), RAID Type and returns Usable Capacity (TB), Raw Capacity (TB), Chart.
If the result changes your decision, verify the current quote, rate, eligibility rule, or provider term before acting.
