Abstract
Techniques involve: receiving an input/output request for data stored in a second storage means of a storage system; determining a use frequency of the data; moving the data from the second storage means into a first storage means in the storage system if it is determined that the use frequency is higher than a threshold frequency and the input/output request is a read request, an input/output speed of the first storage means being higher than that of the second storage means; and writing, if it is determined that the use frequency is higher than the threshold frequency and the input/output request is a write request that includes update data, the update data as the data into the first storage means. Accordingly, the storage performance can be improved without affecting the input/output traffic, which not only can reduce the operating cost, but also can improve user experience.
