What is Block Storage?

Deploy flash-backed block storage in granular increments, from 1,000-12,000 GB, and customize it all with a variety of capabilities. Increase storage capacity available to your virtual and bare metal servers with a maximum of 48k IOPS.

Block Storage features

Flexible customization

Choose simple, predefined Endurance tiers with per-GB pricing—ideal for most general purpose workloads. Or, fine tune your environment with allocated IOPS and Performance options—ideal for well-understood workload requirements.

Smart and safe management

Stay confident with storage designed to protect against data loss during maintenance or failures with at rest data encryption, volume duplication and snapshots and replication.

Predictable billing

Lock in your costs without the surprise of hidden fees or additional charges. Help ensure lower costs with TB increments, and for greater flexibility you can choose between hourly or monthly billing for long-term or short-term storage needs.
