Abstract: Systems and methods are disclosed for data storage redeployment. For example, a controller of a data storage array can implement a process to determine when, or if, to redeploy a data storage device from a first data storage usage or tier having a first performance requirement to a second data storage usage or tier having a second performance requirement. In some embodiments, the first data storage tier performance requirement is for hot-data storage, and the second data storage tier performance requirement is for cold-data storage. Various criterion (e.g., a data storage device performance metric) threshold, such as a workload (e.g., LBAs written, LBAs read, or both) of the data storage device or bit error rate (BER), may be utilized in a redeployment determination.
