Dynamically selecting segment heights in a heterogeneous RAID group

A method, comprising:

• selecting a segment height based on erase block sizes of a plurality of solid-state storage devices, responsive to identifying the plurality of solid-state storage devices comprise two or more solid-state storage devices having different erase block sizes;
• writing a data segment using the segment height to a data stripe across the two or more solid-state storage devices having different erase block sizes, the data stripe divided into multiple segments with each segment having the segment height;
• and
• storing the segment height in metadata associated with the data segment.

A non-transitory computer readable storage medium storing instructions, which when executed, cause a processing device to:

• selecting a segment height based on erase block sizes of a plurality of solid-state storage devices, responsive to identifying the plurality of solid-state storage devices comprise two or more solid-state storage devices having different erase block sizes;
• writing a data segment using the segment height to a data stripe across the two or more solid-state storage devices having different erase block sizes, the data stripe divided into multiple segments with each segment having the segment;
• and
• storing the segment height in metadata associated with the data segment.
