ABSTRACT:
An improved USB to ATA bridge circuit that issues a speculative write command upon the completion of an actual write command: The speculative write command assumes that the next write command will write data in a the next sequential data location to that in which data was written by the preceding write command. When the next actual write command is received, the address to which data is to be written is compared to the address used by the speculative write command, if the addresses match, the data is written when the storage device is ready. If the addresses do not match the data transfer is started and immediately stopped.
