Local disks

Last update: March 04 2024

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.

Standard Line

	Drives up to 700 GB	Drives 700 GB
Throughput	300 MB/s	350 MB/s
Performance (read)	12,800 IOPS	19,200 IOPS
Performance (write)	6,400 IOPS	9,600 IOPS

HighFreq Line

	Drives up to 700 GB	Drives 700 GB
Throughput	300 MB/s	350 MB/s
Performance (read)	12,800 IOPS	19,200 IOPS
Performance (write)	6,400 IOPS	9,600 IOPS

Local Disk Features⁠

• SSD NVMe disk.
• The disk subsystem is configured in RAID 10.
• A cloud database can only have one local disk.
• You cannot disconnect from a cloud database and connect to another database.
• You cannot increase directly, you can only change node configuration.
• Deleted with all data when the node is deleted.
