Abstract

A storage system has a first memory, a second memory that include solid-state storage memory, and a processing device. The processing device is to select a mode for each portion of data to be written. Selection of the mode is based at least on size of the portion of data. Selection of the mode is from among modes that include a first mode of writing the portion of data in mirrored RAID form to the first memory for later transfer from the first memory to the second memory, a second mode of writing the portion of data in parity-based RAID form to the first memory for later transfer from the first memory to the second memory, and a third mode of writing the portion of data to the second memory, bypassing the first memory. The processing device is to handle portions of data to be written according to such selection.
