$8/mo

Users: N/A

Storage: 5GB

Limits: Variable workloads only, not for consistent high-throughput

Storage charges extra, data transfer adds up, backup costs separate

Dedicated M10

Popular

$57/mo

Users: N/A

Storage: 10GB

Limits: Entry production tier, may need M30+ for significant workloads

Data transfer $0.02-0.15/GB, backup storage extra, Atlas Search indexing costs

Dedicated M30

$390/mo

Users: N/A

Storage: 40GB

Limits: ~$0.54/hour, still entry-level for larger workloads

All data transfer and backup costs apply, Atlas features may cost extra
