Abstract
A system includes a solid-state storage array having a plurality of solid-state storage devices and a storage controller coupled to the solid-state storage array, the storage controller including a processing device, the processing device to select a segment height based on erase block sizes of the plurality of solid-state storage devices. The processing device is further to program a data segment using the segment height to a data stripe across two or more of the plurality of solid-state storage devices and store the segment height in metadata associated with the data segment.
