Methods, computer program products, computer systems, and the like are disclosed that provide for improved write performance in erasure-coded storage systems in an efficient and effective manner. These can include identifying a data segment, identifying metadata, persisting the data segment to a storage system, storing the metadata in the journal, and persisting the metadata to the storage system. In such embodiments, the metadata is associated with the data segment by virtue of the metadata comprising a fingerprint of the data segment. Further, in such embodiments, the persisting the data segment to the storage system is performed without storing the data segment in a journal, and the storage system is an erasure-coded storage system.
