Abstract

See full text

During operation, the system receives a chunk of data to be written to a non-volatile memory, wherein the chunk includes a plurality of sectors. The system assigns consecutive logical block addresses (LBAs) to the plurality of sectors. In response to determining that a first sector is associated with an existing stream for the chunk, the system appends the first sector to one or more other sectors stored in a first buffer associated with the existing stream. The system detects that a total size of the stored sectors in the first buffer is the same as a first size of a physical page in the non-volatile memory. The system writes the stored sectors from the first buffer to the non-volatile memory at a first physical page address. The system creates, in a data structure, a first entry which maps the LBAs of the written sectors to the first physical page address.
