Disclosed are systems, computer-readable mediums, and methods for managing client performance in a storage system. In one example, the storage system receives a request from a client to write data to the storage system. The storage system estimates, based on a system metric associated with the storage system reflecting usage of the storage system, a requested write QoS parameter for storing the data by the storage system during a first time period. The storage system further determines a target write QoS parameter for the client based on the estimated requested write QoS parameter and an allocated write QoS parameter for the client. Then, the storage system independently regulates read performance and write performance of the client using a controller to adjust the write performance toward the determined target write QoS parameter within the first time period based on feedback regarding the estimated requested write QoS parameter.
