Reliability 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 a threshold value plus data blocks', it will activate the static wear leveling, replacing the less frequently used user blocks with the high erase count free blocks.

ATA Command Specifications FLUSH CACHE (E7h) This command is used by the host to request the device to flush the write cache. If there is data in the write cache, that data shall be written to the media. The BSY bit shall remain set to one until all data has been successfully written or an error occurs. IDENTIFY DEVICE (ECh) This command reads out 512Bytes of drive parameter information. Parameter Information consists of the arrangement and value as shown in the following table.
READ BUFFER (E4h) The READ BUFFER command enables the host to read a 512-byte block of data. WRITE BUFFER (E8h) This command enables the host to write the contents of one 512-byte block of data to the device’s buffer. Power Management Feature Set CHECK POWER MODE (E5h or 98h) The host can use this command to determine the current power management mode. IDLE (E3h or 97h) This command causes the device to set BSY, enter the Idle mode, clear BSY and generate an interrupt.
Security Mode Feature Set SECURITY SET PASSWORD (F1h) This command sets user password or master password. The host outputs sector data with PIO data-out protocol to indicate the information defined in the following table. Security set Password data content1 Word 0 Content Control word Bit 0 Identifier 0=set user password 1=set master password Bits 1-7 Reserved Bit 8 Master Password 0=High Capability 1=Maximum Bits 9-15 Reserved 1-16 17 18-255 Password (32 bytes) Master Password identifier.
SECURITY DISABLE PASSWORD (F6h) Disables any previously set user password and cancels the lock. The host transfers 512 bytes of data, as shown in the following table, to the drive. The transferred data contains a user or master password, which the drive compares with the saved password. If they match, the drive cancels the lock. The master password is still saved. It is re-enabled by issuing the SECURITY SET PASSWORD command to re-set a user password.
