A computer system can dynamically manage the performance of a data storage system that includes sets of data storage devices. One set of the data storage devices can include read-intensive (RI) solid-state drives (SSDs). The computer system can detect, in response to a specified number of input/output operations per second (IOPS) of data contained on the RI SSDs exceeding the access density of the RI SSDs divided by the portion of data locations of the RI SSDs containing the data, a free area within the RI SSDs having space for additional data. Additional data within the data storage system that has a required access time less than a specified access time threshold and an access frequency less than a specified access frequency threshold can also be detected. In response, the detected additional data can be moved to the free area within the RI SSDs.
