The Maximum Read Speed Supported field is set to 160Ch for CD media and is set to 1AA2h for DVD media. It does not reflect the 
maximum read speed for each medium type and format. If no disc is mounted in the drive, the field is set to the same value as DVD. 

The Current Read Speed filed is set to 160Ch for CD media and is set to 1AA2h for DVD media. It does not reflect the actual read 
speed. If no disc is mounted in the drive, the field is set to the same value as DVD. 

The Maximum Write Speed Supported field is set to the same value of the Write Speed Descriptor #1 data which is returned for the 
GET PERFORMANCE command.   

The Current Write Speed filed is set to the same value of the Write Performance data which is returned for the GET 
PERFORMANCE command. 

The Number of Logical Unit Write Speed Performance Descriptor Tables and The Logical Unit Write Speed Performance Descriptors 
#1 - #8 are set to the suitable values by using the same algorism as the GET PERFORMANCE command. 

This command is defined in a legacy specification (MMC-2 Revision 10a). 

The RelAdr bit is n ot supported and must set to 0.   

If the Streaming bit in the CDB of the READ (12) command is set to one, the FUA bit shall be set to zero. The setting of the 
Streaming bit is no effect on the operation. 

This command is used for checking the drive. 

The specifications of this command are vendor unique.
