The Write Same command instructs the Target to write a single block of data transferred to the Target from the
Initiator to a number of sequential logical blocks. This command is useful for writing large data areas without sending
all of the data over the SCSI bus. See the WRITE(10) command description for the definition of the WRPROTECT
field.
