Partial execution of a write command from a host system

A non-transitory computer storage medium storing instructions which, when executed in a memory sub-system, causes the memory sub-system to perform a method, the method comprising:

• receiving, in the memory sub-system, a first write command from a host system, the first write command identifying a first input/output size;
• identifying, by the memory sub-system based on a media physical layout, a second input/output size for executing the first write command in the memory sub-system, the second input/output size being smaller than the first input/output size;
• executing, in the memory sub-system, the first write command according to the second input/output size;
• transmitting, from the memory sub-system to the host system, a response for the first write command, the response identifying the second input/output size, wherein the host system is configured to generate a second write command to write at least data that is identified in the first write command via the first input/output size but not included in execution of the first write command according to the second input/output size;
• and
• receiving, in the memory sub-system, the second write command from the host system.

A memory sub-system, comprising:

• a plurality of media units capable of writing data concurrently;
• and
• at least one processing device configured to:
• receive, in a memory sub-system, write commands from a host system;
• identify, by the memory sub-system based on page maps of a plurality of media units that are available to execute the write commands concurrently, preferred input/output sizes for executing the write commands in the plurality of media units respectively;
• execute, in the plurality of media units, the write commands concurrently according to the preferred input/output size;
• and
• transmit, from the memory sub-system to the host system, responses to the write commands respectively, the responses configured to respectively identify the preferred input/output sizes according to which data has been stored in the memory sub-system in execution of the write commands.
