1. A storage system comprising:
a plurality of storage devices; and
a storage system controller, operatively coupled to the plurality storage devices, the storage system controller configured to:
determine a second data segment associated with a first data segment based on a first content-dependent feature of the first data segment;
determine a content-dependent delta between the first content-dependent feature and a second content-dependent feature of the second data segment; and
utilize the content-dependent delta to reduce data stored for the first data segment, wherein the content dependent delta is stored in the storage system.
