Zettabyte Object Storage (ZOS) provides three types of storage: Standard Storage, Infrequent Access (IA) Storage , and Archive Storage. Each type has distinct features and is suitable for different scenarios. You can select the appropriate storage type based on the frequency of data access, availability requirements, and associated costs.

	Standard Storage	Low Frequency Storage	Archival Storage
Storage Costs	Medium	Low	Very low
Access Frequency	High	Low	Very low
Data Availability	High	High	Low
Data Access Latency	Access to large files: low Highly concurrent access to small files: low	Access to large files: low Highly concurrent access to small files: relatively high	Access to large files: low Highly concurrent access to small files: relatively high
Minimum Storage Time	None	30 days	90 days
Data Security	High	High	High
Data Storage Purpose	For frequent access	For infrequent access	For long-term archive and backup
Data Retrieval	Not Involved	Charged based on the amount of data retrieved	Charged based on the amount of data unfrozen
Scenario	This storage type is suitable for scenarios that demand frequent access (multiple times per month). Examples include mobile applications, websites, audio/video content, social networking images, and big data analysis.	This storage type is suitable for scenarios that require infrequent access (approximately once per month). Examples include data backup and monitoring data storage.	This storage type is suitable for scenarios where data needs to be stored for high compliance requirements and is accessed very infrequently (approximately once per year). Examples include archival data, medical images, and long-term backups.

Note:

Both IA storage and Archive storage have limitations on the minimum storage duration. You will still be billed until the minimum duration is reached even if you delete or overwrite the data in advance or switch to another storage type. The minimum storage duration for IA storage is 30 days, and that for Archive storage is 90 days.
