19.62 WRITE SAME (16) - (93)
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.
