Abstract
Systems, methods, and data storage devices for dynamic mode selection for hybrid MLC/SLC data storage devices are described. Storage operations at a plurality of storage devices from a host device may be processed, wherein each storage device of the plurality of storage devices comprises a plurality of partitions including multi-level cell blocks and single-level cell blocks and multi-level cell blocks may be selectively written in a single-level write operation. A usage value is determined for each partition of the plurality of partitions at each storage device of the plurality of storage devices. A storage device of the plurality of storage devices may be dynamically selected based on the usage value for single-level cell blocks of the selected storage device having available single level cell blocks. New data may then be stored at the dynamically selected storage device of the plurality of storage devices.
