1. A computer-implemented method comprising:
receiving, at a serial advanced technology attachment (SATA) storage device, a data block from a source, the data block to be written to a memory of the SATA storage device;
ascertaining that an entropy of the data block is indicative of encrypted data based only on determining a respective entropy amount of only one sub-block of the data block and not based on a respective amount of entropy determined for another sub-block of the data block, wherein the data block comprises a plurality of sub-blocks; and
in response to ascertaining that the entropy of the data block is indicative of encrypted data, writing the data block to the memory of the SATA storage device.
