Our review
Pros
  • Five volume types cover general, high-IOPS, throughput, and ML workloads.
  • Provision capacity, IOPS, and throughput independently per volume.
  • Replication, snapshots, sharing, encryption, and storage pools support varied operations.
  • Profiles support tiered, custom, and defined-performance configurations.
  • Supports volumes up to 32,000 GB and performance up to 64,000 IOPS.
  • Offers snapshots, encryption, and provisioning through Terraform, CLI, API, and console.
Cons
  • There is no free plan for evaluating the service.
  • Usage-based pricing separates capacity, performance, and replication charges.
  • Some sharing and replication capabilities apply only to supported volume types.
  • There is no multi-attach support for sharing a volume across instances.
  • Cross-region protection uses snapshot copying rather than live volume replication.
  • The service is paid and pricing varies by region, profile, capacity, and billing period.
