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 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 BCH8 ECC algorithm per 512 bytes. BCH8 can correct up to 8 random error bits within 512 data
bytes.
Bad-block management
When the flash encounters ECC failed, program fail or erase fail, the controller will mark the block as bad block to
prevent the used of this block and caused data lost later on.

RECALIBRATE (10h)
The current drive performs no processing if it receives this command. It is supported for backward compatibility with
previous devices.
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.
SECURITY ERASE PREPARE (F3h)
This command shall be issued immediately before the Security Erase Unit command to enable erasing and unlocking.
This command prevents accidental loss of data on the drive.
SECURITY ERASE UNIT (F4h)
The host uses this command to transfer 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
deletes user data, disables the user password, and 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.
