Abstract
A data storage array is presented that includes a plurality of storage drives each comprising storage media with a first storage region and a shingled magnetic recording (SMR) storage region. The data storage array includes a control system communicatively coupled to the storage drives and configured to receive a write operation over a host interface for storage of write data by the data storage array. Responsive to the write operation, the control system is configured to cache the write data in first storage regions of two or more of the storage drives prior to transfer of the write data into at least an SMR storage region of a storage drive associated with the write operation.
