Local disks

The local disk is connected directly to the compute server through the PCIe interface via NVMe protocol. Therefore, a local disk can only be created with cloud database cluster.

The local disk has no network latency, so it is suitable for tasks that are sensitive to read and write speeds.

Performance and throughput

Local disk performance and throughput in fixed Standard Line and HighFreq Line configurations depends on the disk size.

up to 700 GB
