Hetzner Cloud Volumes
Hetzner Cloud Volumes is SSD-based, network-attached block storage for expanding storage on Hetzner Cloud Servers.
What Hetzner Cloud Volumes is
Hetzner Cloud Volumes is SSD-based, network-attached block storage for expanding storage on Hetzner Cloud Servers. Hetzner describes it as suitable for data-intensive workloads, databases, and log storage. Each data block is kept on three physical servers in Hetzner data centers. Volumes range from 10 GB to 10 TB and can be enlarged in 1 GB increments, but not reduced. They can be mounted manually or automatically; automatic setup offers EXT4 and XFS filesystems. After increasing a volume, customers must extend the filesystem themselves in the operating system. Documented performance is up to 5,000 sustained read/write IOPS and 200 MB/s, with bursts up to 7,500 IOPS and 300 MB/s. A volume attaches to one Cloud Server at a time and cannot be attached to a dedicated server. Hetzner does not provide volume backups or snapshots, and server backups and snapshots exclude attached volumes. The service is billed hourly with a monthly price cap, but no price is stated.
Good

Who it suits
It suits customers who need SSD block storage for Hetzner Cloud Servers, including data-intensive workloads, databases, or logs. Users should be prepared to manage filesystem expansion and separate volume backups themselves.
Verdict
Hetzner Cloud Volumes provides expandable SSD storage for Cloud Servers, with documented performance limits and API management. The lack of included backups and the one-server attachment limit are important constraints to plan around.
