Key value data placement according to expected reads

A data storage device includes a memory device and a controller coupled to the memory device. The controller is configured to receive key value (KV) pair data, group a plurality of KV pair data based on a data clustering value, aggregate the grouped plurality of KV pair data, and program the aggregated plurality of KV pair data to the memory device. A length of the KV pair data is less than a size of a flash management unit (FMU). The KV pair data includes a key and a value. Each KV pair data of the plurality of KV pair data has a length less than the size of the FMU. The received KV pair data is stored in a temporary location and grouped together in the temporary location. The grouping is based on a similarity of characteristics of plurality of KV pair data.
