+ **same**
+ This option is deprecated. Use write_same instead.
+ **write_same_ndob**
+ Issue WRITE SAME(16) commands as above but with the No Data Output
+ Buffer (NDOB) bit set. No data will be transferred to the device with
+ this bit set. Data written will be a pre-determined pattern such as
+ all zeroes.
+ **write_stream**
+ Issue WRITE STREAM(16) commands. Use the **stream_id** option to specify
+ the stream identifier.
+ **verify_bytchk_00**
+ Issue VERIFY commands with BYTCHK set to 00. This directs the
+ device to carry out a medium verification with no data comparison.
+ **verify_bytchk_01**
+ Issue VERIFY commands with BYTCHK set to 01. This directs the device to
+ compare the data on the device with the data transferred to the device.
+ **verify_bytchk_11**
+ Issue VERIFY commands with BYTCHK set to 11. This transfers a
+ single block to the device and compares the contents of this block with the
+ data on the device beginning at the specified offset. fio's block size
+ parameter specifies the total amount of data compared with this command.
+ However, only one block (sector) worth of data is transferred to the device.
+ This is similar to the WRITE SAME command except that data is compared instead
+ of written.
+
+.. option:: stream_id=int : [sg]
+
+ Set the stream identifier for WRITE STREAM commands. If this is set to 0 (which is not
+ a valid stream identifier) fio will open a stream and then close it when done. Default
+ is 0.
