Vultr Block Storage comes in two classes, HDD and NVME, each of which has different performance levels.
- NVME Block Storage is high performance class, which targets 10000 IOPS and 400 MiB/sec per attached block volume.
- HDD Block Storage is the cost-optimized class, which targets 500 IOPS and 100 MiB/sec per attached block volume.
When using Block Storage, clients can temporarily exceed the listed performance targets by up to 50% for about one minute. This burst capability is automatic and gradually returns to the standard target values if sustained I/O activity continues beyond that period. Once the volume’s activity remains below the configured limits for a sufficient duration, a new performance burst becomes available again.
These target levels represent
upper performance limits rather than minimum baselines. Since all block storage relies on a redundant network storage architecture that is shared across customers, and performance depends on the complexity of individual workloads and application behaviors,
no absolute guarantees can be made about the performance that any particular user will experience.
