Standard: Standard storage provides a general object storage service, which is applicable to hotspot data that is frequently accessed or data that requires low latency and high throughput, such as audio, video, and picture files, and static website resources.
Low frequency: Low frequency storage is applicable to infrequence access scenarios, where data is stored for a long time and seldom accessed. This storage type reduces storage fees. At the same time, it keeps access delay within milliseconds. When you retrieve data, you can obtain data immediately without the need to wait. However, this storage type places a limit on the storage duration. If you delete objects that are stored for less than 30 day, some fees may occur. In addition, data acquisition also incurs fees, regardless of whether you acquire the data from an internal network or the Internet.
Archive: Archive storage is applicable to extremely infrequent access scenarios, where data is stored for a long time and rarely accessed. This storage type provides the same data reliability and service availability as standard storage and low frequency storage with a much lower price. However, it takes 1 to 10 minutes to restore data to the readable state. You can use archive storage to store data that requires long-term storage, such as medical images, archives, service logs, and stock footages. Archive storage also places a limit on the storage duration. If you delete objects that are stored less than 90 days, some fees may occur. In addition, reading data from archive storage also incurs data retrieval fees.
