Embodiments of the present disclosure relate to an electronic apparatus that includes a metadata generator, to generate an extents table (ET) that lists one or more extents pages (EPs), where an EP is a fixed size, and where the one or more EPs store one or more extents. An extent includes an allocation indication for a cluster in a memory device, where a number of the extents corresponds to a number of clusters of the memory device, where a subset number of the extents is stored in one of the one or more EPs, and where the subset number is based on the fixed size of the EP. The electronic apparatus further includes a metadata updater, to modify the allocation indication in the extent stored in the one of the one or more EPs, based on a corresponding change in an allocation of the cluster in the memory device.
