Systems and techniques for performing a data transaction are disclosed that provide improved cache performance by pinning recovery information in a controller cache. In some embodiments, a data transaction is received by a storage controller of a storage system. The storage controller determines whether the data transaction is directed to a data stripe classified as frequently accessed. Data associated with the data transaction and recovery information associated with the data transaction are cached in a cache of the storage controller. The recovery information is pinned in the cache based on the data transaction being directed to the data stripe that is classified as frequently accessed, and the data is flushed from the cache independently from the pinned recovery information.
