capacity, high speed, and low power consumption
without moving parts which design for take the place
of traditional hard disk drive. It provides fast read and
write performance for high end system such as
server and storage system. Build in advance ECC
and global wear-leveling provide a durable solution is
perfect replacement storage device for Server
systems, Storage systems, PCs, Laptops and
gaming systems.

Wear-Leveling algorithm

The controller supports static/dynamic wear leveling. When the host writes data, the controller will find and use the block
with the lowest erase count among the free blocks. This is known as dynamic wear leveling. When the free blocks' erase
count is higher than the data blocks', it will activate the static wear leveling, replacing the not so frequently used user
blocks with the high erase count free blocks.

ECC algorithm

The controller use Reed Solomon code or BCH code option

SMART Write Log Sector (subcommand D6h)

This command writes 512 bytes of data to th e s pecified log sec tor. LBA Low and Sector Co unt regis ters shall be se t to
specify the log address and sector number to be written.

SMART Enable Operations (subcommand D8h)

This subcommand enables access to all SMART capabilities. Prior to receipt of a SMART Enable Operations
subcommand, Attribute Values are neither monitored nor saved by the de vice. Th e sta te of SMART—eithe r enab led or
disabled—will be preserved by the device across power cycles. Once enabled, the receipt of subsequent SMART
Enable Operations subcommands will not affect any of the Attribute Values.

SMART Disable Operations (subcommand D9h)

This subcommand disables all SMART capabilities. After receipt of this subcommand the device disables all SMART
operations. Non self-preserved Attribute Values will no lo nger be monitored. The state of SMART—either enabled or
disabled—is preserved by the device acro ss pow er cycles. N ote that this subc ommand does n ot prec lude the device's
power mode attribute auto saving.
After receipt of the SMART Disable Oper ations subcommand from the host, all other SMART subcommands exc ept
SMART Enable Operations are disabled and will be aborted by the device returning the error code as specified in
“SMART Error Codes”.
Any Attribute Values accumulated and saved to volatile memory prior to receipt of the SMART Disable Operations
command will be preserved in the device's Attribute Data Sectors. If the device is re-enabled, these Attribute Values will
be updated, as needed, upon receipt of a SMART Read Attribute Values or a SMART Save Attribute Values command.

SMART Return Status (subcommand DAh)

This subcommand is used to communicate the reliability status of the device to the host's request. Upon receipt of the
SMART Return Status subcommand the device saves any updated Attribute Values to the reserved sector, and
compares the updated Attribute Values to the Attribute Thresholds.

SMART Enable/Disable Automatic Off-line (subcommand DBh)

This subcommand enables and disables the optional feature that ca use the device to perform the set of off-line data
collection activities that automatically collect attribute data in an off-line mode and then save this data to the device's
nonvolatile memory. This subcommand may either cause the devic e to automa tica lly initiate o r re sume per formanc e of
its off-line data collection activities or cause the automatic off-line data collection feature to be disabled. This
subcommand also enables and disables the off-line read scanning feature th at cause the device to perform the en tire
read scanning with defect reallocation as the part of the off-line data collection activities. The Sector Count register shall
be set to specify the feature to be enabled or disabled:

Sector Count Feature Description

00h Disable Automatic Off-line
F8h Enable Automatic Off-line

A value of zero written by the host into the device's Sector Count re gister before issuing this sub command shall cause
the automatic off-line data collection feature to be disabled. Disabling this feature does not preclude the device from
saving attribute values to nonvolatile memory during some other no rma l ope ra tion s uc h as du ring a power-on, during a
power-off sequence, or during an error recovery sequence. A value of F8h written by the host into the device's Sector
Count register before issuing this subcommand shall cau se the au tomat ic Off -line data collection feat ure to be enabled.
Any other non-zero value written by the host into this register before issuing this subcommand is vendor specific and will
not change the current Automatic Off-Line Data Collection and Off-line Read Scanning status. However, the device may
respond with the error code specified in “SMART Error Codes”.

Security

Default setting

The Flash SSD is shipped with master password set to 20h value (ASCII blanks) and the lock function disabled. The
system manufacturer/dealer may set a new master password by using the SECURITY SET PASSWORD command,
without enabling the lock function.

Initial setting of the user password

When a user password is set, the drive automatically enters lock mode by the next powered-on.

SECURITY mode operation from power-on

In locked mode, the Flash SSD rejects media access commands until a SECURITY UNLOCK command is successfully
completed.

Password lost

If the user password is lost and High level security is set, the drive does not allow the user to access any data. However,

If the user password is lost and Maximum security level is set, it is impossible to access data. However, the drive can be
unlocked using the ERASE UNIT command with the master password. The drive will erase all user data and unlock the
drive.

SATA Optional Features

Power Segment Pin P11

Pin P11 of the power segment of the device connector may be used by the device to provide the host with an activity
indication. The activity indication provided by pin P11 is primarily for use in backplane applications.

Asynchronous Signal Recovery

Phy may support asynchronous signal recovery for those applications where the usage model of device insertion into a
receptacle (power applied at time of insertion) does not apply.
When signal is lost, both the host and the device may attempt to recover the signal. A host or device shall determine loss
of signal as represented by a transition from PHYRDY to PHYRDYn, which is associated with entr y into states LSI:
NoCommErr or LS2:NoComm within the Link layer. Note that negation of PHYRDY does not always constitute a loss of
signal. Recovery of the signa l is associated with exit from state LS2:NoComm. If the device attempts to recover the
signal before the host by issuing a COMINIT, the device shall retur n its signature following completion of the OOB
sequence which included COMINIT. If a host supports synchronous signal recovery, when the host receives an
unsolicited COMINIT, the host shall issue a COMRESET to the device. An unsolicited COMINIT is a COMINIT that was
not in response to a preceding COMRESET, as defined by the host not being in the HP2:HR_AwaitCOMINIT state when
the COMINIT signal is first received.
When a COMRESET is sent to t he device in response to an unsolicited COMINIT, t he host shall set the Stat us register to
7Fh and shall set all other Shadow Command Block Registers to FFh. When the COMINIT is received in response to the
COMRESET which is associated with entry into state HP2B:HR_ AwaitNoCOMINIT, the Shadow Status regis ter value
shall be updated to either FFh or 80h to reflect that a device is attached.
