A hard disk unit includes a disk, controller microprocessor, host bus interface, buffer memory, buffer memory controller and disk formatter. The bus interface receives write operations, and the corresponding write operation data is stored in the buffer memory. The buffer memory controller also includes a set of address registers and a set of block count registers. The microprocessor loads the address registers with the buffer memory addresses of data of multiple write operations and loads the block count registers with the size of the corresponding data. The microprocessor then issues a single command to the buffer memory controller to transfer the data from the buffer memory to the disk formatter. The address registers and block count registers enable the data of multiple write operations to be transferred and written to a disk in an order other than the order in which the write operations were received at the bus interface.
