Abstract
Systems and methods for storage systems using storage device monitoring for load balancing are described. Storage devices may be configured for data access through a common data stream, such as the storage devices in a storage node or server. Data operations from the common data stream may be distributed among the storage devices using a load balancing algorithm. Performance parameter values, such as grown bad blocks, program-erase cycles, and temperature, may be received for the storage devices and used to determine variance values for each storage device. Variance values demonstrating degrading storage devices may be used to reduce the load allocation of data operations to the degrading storage devices.
