Rather than use one long folding operation to fold data from single-level cell (SLC) blocks into a multi-level cell (MLC) block, a storage system uses a multi-stage folding operation. By breaking up the folding process into stages, SLC blocks involved in an earlier stage can be released prior to a subsequent stage being performed. This can increase performance of the storage system by releasing SLC source blocks sooner and reducing an SLC block budget requirement.

Storage system and folding method for enhanced performance

Apparatus, systems, methods, and computer program products for buffering storage device data in a host memory buffer (HMB) are presented. A non-volatile memory and a controller are in communication with a non-volatile memory. A controller is configured to receive an input/output (I/O) operation including data. A controller is configured to transmit at least a portion of data to an HMB of a host device separate from a non-volatile memory and a controller for storage until a trigger event occurs.
