gp3 saves 20.0% vs gp2
You'd save $120.00/year by switching from gp2 to gp3. gp3 is cheaper at baseline with independently adjustable IOPS and throughput.
📌
io2 vs io1: Same price per GB and IOPS, but io2 offers 99.999% durability (vs 99.8–99.9% for io1). Always pick io2 over io1 for new deployments.

Best For... Decision Guide

gp3: Most workloads. Best price/performance for general SSDs. Independently tune IOPS + throughput.
io2: Databases needing >16K IOPS or 99.999% durability. Production MySQL, PostgreSQL, Oracle.
st1: Big data, Kafka, data warehouses, log processing. Sequential read/write at low cost.
sc1: Cold archives, infrequent access. Cheapest AWS block storage.
Azure Premium v2: Azure workloads needing flexible IOPS/throughput tuning, like gp3 on AWS.
GCP PD-Balanced: GCP general purpose with solid included IOPS. Good default choice.
Pricing Notes
  • • AWS prices: us-east-1 region. Azure/GCP: US equivalent regions
  • • gp2 IOPS calculated as min(3 × GB, 16,000) — included in base price
  • • io2 IOPS pricing: $0.065/IOPS up to 32K, $0.046/IOPS above 32K
  • • HDD types (st1/sc1) have fixed IOPS and throughput limits
  • • Snapshot costs not included (add ~$0.05/GB-month for AWS)
  • • Prices updated Q1 2026 — verify at provider pricing pages
