The access efficiency of data will generally decrease after converting on-demand standard storage to low-frequency storage, as low-frequency storage is optimized for data that is accessed less often. The exact slowdown depends on the specific implementation of the storage service, but it typically involves increased latency and potentially higher retrieval costs when accessing the data.
For example, if a file stored in standard storage can be retrieved in milliseconds, the same file in low-frequency storage might take several seconds to retrieve due to additional processing steps or physical relocation of data from slower media.
If you're using Tencent Cloud, the COS (Cloud Object Storage) service offers different storage classes, including Standard and Infrequent Access (IA). When data is moved from Standard to IA, access latency may increase slightly, but it remains suitable for data accessed less than once a month. For even lower-frequency data, Archive Storage can be used, though retrieval times are longer (minutes to hours).
To minimize performance impact, evaluate your data access patterns before switching storage classes. Use Tencent Cloud COS Lifecycle Management to automate transitions based on access frequency.
