Systems and methods for data storage management technology that optimizes the creation and storage of data objects. An example method may involve: receiving a request to create a data object; storing a first portion of the data object in a first data storage; determining a location in a second data storage in view of a predicted size of the data object and an access unit size of the second data storage; copying, by a processing device, the first portion of the data object from the first data storage to the location in the second data storage; and in response to receiving a second portion of the data object, directly storing the second portion in the second data storage.
