Common Mistakes to Avoid
❌ Growth rate varies by workload
Database growth can be 50-100%/year. Cold archive storage: 5-10%/year. User file shares: 20-30%/year. Measure actual growth before projecting.
❌ Rule of 72
Divide 72 by growth rate to find doubling time. 30% growth: doubles every 2.4 years. 20%: 3.6 years.
Frequently Asked Questions
Average enterprise storage growth?
15-30%/year. Data doubles roughly every 2-5 years depending on industry.
When to buy storage?
Plan capacity 1-2 years ahead. Buy on-premise when long-term ownership is cheaper. Cloud for variable/burst storage.
Cloud storage cost trend?
Cloud storage costs drop ~20% per year historically. On-premise amortizes over 5 years. Compare TCO for your workload.
