The disclosure is related to systems and methods for checking the integrity of a data transfer to or from a buffer or other data storage medium. Check values can be added to a data object in a data object based file system. From the check values, a device receiving the data object may determine an integrity or validity of the received data object based on the check values. In a particular embodiment, a hash value may be determined based on the check values. The hash value may be stored in the metadata of the transferred data object. The receiving device may re-calculate the hash value from the check values and compare it to the stored hash value to determine an integrity of the received data object.
