Glossary

Cloud Block Storage

The HDD cloud disk is phased out currently. The following guide is only for reference when you are using the HDD cloud disk.

HDD cloud disks are the first generation of cloud disks provided by Tencent Cloud. It is suitable for business scenarios with low I/O loads where data is not accessed frequently. It uses magnetic storage, and a three-copy distributed mechanism to implement highly reliable data storage.

For scenarios with infrequent requests, such as system logs, enterprise work files, data warehouses, small-sized blogs, and BBS, we recommend using HDD cloud disks to reduce costs.

Metrics	HDD Cloud Disk
Random IOPS	Offers the capacity options of 10 GB - 16000 GB, and hundreds of random IOPs choices.
Throughput (MB/s)	Supports the I/O throughputs up to 50 MB/s.
