description Storage systems are disclosed. For instance, a storage system comprises a first storage device of a first type and a second storage device of a second type, and the first storage device has a higher access velocity than the second storage device. A threshold indicating a volume limit of data stored in the first storage device can be determined. Data, which is specified by a write request for writing data to the storage system, is written to the first storage device in response to determining the data amount in the first storage device is lower than the threshold. A read request from a client device is processed based on data stored in the first storage device. Consequently, the first storage device with a higher access velocity in the storage system may be utilized as much as possible, so that storage device latency in the storage system is managed more effectively.
