Abstract: In a data storage method, a storage system comprises first and second medium layers for data storage, wherein the performance of the first medium layer is different from the performance of the second medium layer. Based on the performance difference between the two layers, the storage system stores data in the first medium layer and the second medium layer based on different erasure code ratios. The different erasure code ratios correspond to different write amplification, and result in different storage space utilization.
