Dynamic use of segment or zone power loss protection in a flash device

A tangible, non-transitory, computer-readable media having instructions thereupon which, when executed by a processor, cause the processor to perform a method comprising:

• defining a plurality of zones of solid-state storage memory, each zone comprising a portion of the solid-state storage memory having a data write requirement for the zone, the data write requirement associated with reliability of data reads;
• tracking whether each zone is an open zone having one or more non-durable data segments or a closed zone having one or more durable data segments;
• and
• monitoring power loss protection activation for each zone, the power loss protection comprising arranging to fulfill the data write requirement for the zone.

A storage system, comprising:

• solid-state storage memory having a plurality of zones, each zone comprising a portion of the solid-state storage memory having a data write requirement for the zone for reliability of data reads;
• and
• a processing device, to:
• track, in a data structure, each of the plurality of zones, including indicating open zones having one or more non-durable data segments and closed zones having one or more durable data segments that fulfill the data write requirement for the zone in the solid-state storage memory;
• and
• monitor power loss protection activation for each zone, the power loss protection comprising arranging to fulfill the data write requirement for the zone, in event of power loss.
