Abstract
This disclosure is related to media cache cleaning based on workload. In some examples, a read-modify-write (RMW) operation may merge new data with existing data and the merge may be interrupted without losing the amount of work already processed. This can be particularly useful for shingled magnetic recording (SMR) systems that utilize a large cache, such as a media cache, that can accumulate many entries that might need to be merged with existing data. An RMW operation can be interrupted such that a host command does not timeout.
