Volume Storage Classes

Storage Classes

Plan13 Cloud offers multiple storage classes to meet the performance, durability, and cost requirements of your workloads. Each class is designed around specific I/O patterns—from archival backups to high-performance databases.

All volume types are fully integrated with our compute infrastructure and available across all regions. Pricing is transparent and based on provisioned capacity (€/GiB per month). Choose the class that aligns with your workload characteristics:

  • Capacity Optimized – for cost-efficient, infrequently accessed data
  • General Purpose – for boot volumes and typical application storage
  • Performance Optimized – for IOPS-intensive, latency-sensitive workloads

General Purpose (gp1)

General purpose Enterprise Grade SSD-backed volume with balanced IOPS and throughput for everyday workloads and boot volumes.

Features
  • 7K IOPS per 100 GiB
  • Bandwidth per 100 GiB: 20,625 MB/s
  • Availability: 99,9543%
  • Durability: 99,9600%
  • Latency-optimized for small-to-medium I/O
Use Cases
  • Virtual machine boot disks
  • Web servers and app servers
  • Development environments
  • Medium-sized databases (Postgres, MySQL)
Choose If
  • You want a balanced SSD volume for most workloads
  • You need consistent IOPS and low latency
  • You want good performance at a moderate price
Avoid If
  • Your workload requires extremely high IOPS or throughput
  • You run high-performance databases or real-time analytics

Latency Optimized (io1)

Performance-optimized SSD storage with replication for critical workloads requiring high IOPS and strong reliability.

Features
  • 14K IOPS per 100 GiB
  • Bandwidth per 100 GiB: 41,250 MB/s
  • Availability: 99,9543%
  • Durability: 99,9992%
  • Consistent low-latency access
Use Cases
  • High-performance databases (Postgres, Cassandra, Elasticsearch)
  • Financial or transactional workloads
  • Real-time analytics
  • Enterprise-grade application clusters
Choose If
  • Your workload is sensitive to latency and downtime
  • You need fast and consistent response times
  • You can’t afford performance degradation during load
Avoid If
  • You are storing static or infrequently accessed data
  • You’re optimizing purely for cost

Capacity Optimized (st1)

Archival-optimized volume for cost-effective, infrequent access. Ideal for backups and cold data with low IOPS requirements.

Features
  • Availability: 99,7260%
  • Durability: 99,9992%
  • Best price per GiB ratio
  • Ideal for sequential access patterns
Use Cases
  • Backup storage
  • Archive and cold data
  • Long-term logs or observability data
  • Container image or software repositories
Choose If
  • You prioritize low cost per GiB over latency or IOPS
  • Your data is accessed rarely and in bulk
  • Throughput matters more than response time
Avoid If
  • Your workload is sensitive to I/O latency
  • You need high performance for small random reads/writes
