CHAPTER 7 SATA II FEATURE SET

This section describes the SATA II feature set supported in the Samsung Spinpoint M8 drive.

7.1

Device Activity Signal

Spinpoint M8 implemented the Device Activity Signal on the SATA power connector pin-11. The
implementation is based on the SATA II specification. This activity signal is used for indicating the drive
activities, including the queued and non-queued commands. For the host can use this signal to indicate the
command activity.

7.2

Staggered Spin-up Disable Control

Spinpoint M8 implemented the staggered spin-up disable control by using the SATA power connector pin-11.
This pin is multiplexed with the Device Activity Signal support. On power up this pin is used for the spin-up
control. After the device is connected with the host, this pin is used for the Device Activity.

Before the device spins up its media, devices that support staggered spin-up disable control shall detect
whether pin 11 is asserted low by the host. If pin 11 is asserted low the device shall disable staggered spin-up
and immediately initiate media spin-up. If pin 11 is not connected in the host (floating), devices that support
staggered spin-up disable through pin 11 shall enable staggered spin-up.

7.3

Auto-Activate in DMA Setup FIS

Spinpoint M8 implemented the option for the Auto-Activate in DMA Setup FIS. With this feature enabled,
the DMA Setup FIS is automatically activated. This automation help improve the efficiency of the DMA data
transfer. This feature can be enabled by the SATA Set Feature command.

If the Set Feature is not issued, the DMA Setup FIS is not automatically activated.

7.4

Native Command Queuing (NCQ)

Spinpoint M8 supports the NCQ feature of the SATA II command interface. The NCQ feature is unique in
the SATA II implementation which helps device improve the system performance. The implementation is
fully compliant with the SATA II specification.

The  drive  implements  the  NCQ  with  its  proprietary  hardware  and  firmware  to  enhance  the  command
performance.  The  NCQ  hardware  automatically  receives  the  NCQ  commands  from  the  host.  The  hardware
verifies the duplication of the tag number and report tag duplicated error immediately.  The automation of the
hardware  and  firmware  handles  the  NCQ  command  from its  reception  to  the  reordering  and  command
execution.  The  drive  intelligent  firmware  is  capable  of  sorting  the  physical  address  of  the  incoming
commands  and decides the execution order for the best performance.
