How do we calculate the IOPS of AWS gp2 type volume?

2 min read

This article covers:

• Understanding gp2 baseline performance (3 IOPS per GB)
• Burst capability up to 3,000 IOPS
• Burst credit system and replenishment rates
• Performance calculations for volumes under 1TB
• Performance calculations for volumes over 1TB
• IOPS utilization best practices

Key Metrics:

• Baseline: 3 IOPS per GB (minimum 100 IOPS)
• Burst: Up to 3,000 IOPS for ~30 minutes
• Replenishment: ~5 hours to fully replenish
• Average Utilization: Don't exceed 330 IOPS for <1TB volumes

Critical for:

• Optimizing RDS performance
• Avoiding burst credit depletion
• Right-sizing storage volumes
• Cost optimization
