Abstract: The present disclosure relates to stripe management methods, storage systems, stripe management apparatuses, and storage mediums. In one example method, check units in a plurality of stripes are obtained. A first stripe of the plurality of stripes complies with a first erasure code ratio. A new check unit is generated based on the check units in the plurality of stripes. The new check unit and data units in the plurality of stripes belong to a new stripe, the new stripe complies with a second erasure code ratio, and a quantity of data units corresponding to the first erasure code ratio is less than a quantity of data units corresponding to the second erasure code ratio.

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.
