Abstract
A data storage method includes: in response to a stream ID carried by an IO write request of a host satisfying a first preset condition, writing data corresponding to the IO write request into a first storage unit; and in response to the stream ID carried by the IO write request satisfying a second preset condition, writing the data corresponding to the IO write request into a second storage unit, wherein the stream ID indicates write latency requirement information of the data corresponding to the IO write request, wherein a data write latency indicated by the stream ID satisfying the first preset condition is less than the data write latency indicated by the stream ID satisfying the second preset condition, wherein a read and write performance of the first storage unit is higher than the read and write performance of the second storage unit.
