Methods, systems, and devices for zoned random write operations are described. A memory system may receive a set of write commands associated with respective logical block addresses (LBAs) that may be in a sequential order, where the respective LBAs may be associated with a zone. The memory system may write first data to a first physical block address (PBA), where the first data may be associated with a first LBA of the respective LBAs. The memory system may determine whether a second LBA associated with second data is sequential relative to a write pointer associated with the zone. The memory system may write the second data to a second PBA that may be sequential to the first PBA in response to determining that the second logical block address is non-sequential relative to the write pointer and on a value of a bitmap corresponding to the second LBA.
