Product advantages

Updated at：2025-11-03

Stable and reliable

Cloud disk data is stored in real-time with multiple replicas for high availability. In the event of storage node, media, or network switch failures, data is instantly migrated to alternate nodes without impacting service continuity. Compared to local disks, cloud disks support on-demand snapshot backups and rollback recovery, delivering superior reliability and accessibility.

High performance

Cloud disks use a high-performance RDMA storage network linking physical storage nodes and cloud server host machines. Along with proprietary hardware storage technology, this enables millions of IOPS and ultra-low latency, perfectly suited for high-performance application needs.

High elasticity

No need for advance capacity planning—adjust disk capacity, type, and performance on the fly to meet changing business requirements. With pay-as-you-go models, you can attach or detach instances as needed to adapt to various scenarios.

Massive storage

Each CDS instance supports up to 64 TiB of storage and allows up to 16 CDS instances to be attached to a single cloud server, enabling storage for massive data volumes.
