Abstract
A data storage system includes multiple data storage devices. A subset of the data storage devices are selected to implement log storages for the data storage system, wherein incoming read and write requests are serviced at the data storage devices implementing the log storages. Data written to a volume stored in the data storage system is initially written to the log storage and subsequently flushed to additional data storage implemented using remaining ones of the data storage devices of the data storage system. A controller monitors wear levels of the data storage devices and initiates a reorganization of which data storage devices implement the log storages and which data storage devices implement the additional storage such that discrepancies in wear between the data storage devices is reduced.
