Abstract: A memory sub-system can determine a block granularity for an input/output (I/O) data stream received from a host system. The memory sub-system can determine that the block granularity is different than a memory block granularity of a first memory region in a first namespace of the one or more memory devices, where the first memory region is to store the I/O data stream.

Responsive to a capacity of the accumulated blocks in the second memory region satisfying a threshold criterion, the memory sub-system can migrate the accumulated plurality of blocks from the second memory region to the first memory region.
