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 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.
