Notes:
Display of total bytes varies from file systems, which means not all of the bytes can be used for storage.
Cylinders, heads or sectors are not applicable for these capacities. Only LBA addressing applies.
LBA count addressed in the table above indicates total user storage capacity and will remain the same throughout the lifespan of the
device. However, the total usable capacity of the SSD is most likely to be less than the total physical capacity because a small portion
of the capacity is reserved for device maintenance usages.

5. Flash Management
5.1 Error Correction/Detection
SDM4-M implements a hardware ECC scheme, based on the BCH algorithm. It can detect and correct up
to 16 bits or 24 bits error in 1K bytes.
5.2 Flash Block Management
Current production technology is unable to guarantee total reliability of NAND flash memory array. When
a flash memory device leaves factory, it comes with a minimal number of initial bad blocks during
production or out-of-factory as there is no currently known technology that produce flash chips free of bad
blocks. In addition, bad blocks may develop during program/erase cycles. When host performs
program/erase command on a block, bad block may appear in Status Register. Since bad blocks are
inevitable, the solution is to keep them in control. Apacer flash devices are programmed with ECC, block
mapping technique and S.M.A.R.T to reduce invalidity or error. Once bad blocks are detected, data in
those blocks will be transferred to free blocks and error will be corrected by designated algorithms.
5.3 Wear Leveling
Flash memory devices differ from Hard Disk Drives (HDDs) in terms of how blocks are utilized. For HDDs,
when a change is made to stored data, like erase or update, the controller mechanism on HDDs will
perform overwrites on blocks. Unlike HDDs, flash blocks cannot be overwritten and each P/E cycle wears
down the lifespan of blocks gradually. Repeatedly program/erase cycles performed on the same memory
cells will eventually cause some blocks to age faster than others. This would bring flash storages to their
end of service term sooner. Wear leveling is an important mechanism that level out the wearing of blocks
so that the wearing-down of blocks can be almost evenly distributed. This will increase the lifespan of
SSDs. Commonly used wear leveling types are Static and Dynamic.
5.4 Power Failure Management
Power Failure Management plays a crucial role when experiencing unstable power supply. Power
disruption may occur when users are storing data into the SSD. In this urgent situation, the controller
would run multiple write-to-flash cycles to store the metadata for later block rebuilding. This urgent
operation requires about several milliseconds to get it done. At the next power up, the firmware will
perform a status tracking to retrieve the mapping table and resume previously programmed NAND blocks
to check if there is any incompleteness of transmission.
5.5 ATA Secure Erase
AATA Secure Erase is an ATA disk purging command currently embedded in most of the storage drives.
Defined in ATA specifications, (ATA) Secure Erase is part of Security Feature Set that allows storage
drives to erase all user data areas. The erase process usually runs on the firmware level as most of the
ATA-based storage media currently in the market are built-in with this command. ATA Secure Erase can
securely wipe out the user data in the drive and protects it from malicious attack.

APSDMxxxxG5AN-PXXX
5.6 S.M.A.R.T.
S.M.A.R.T. is an abbreviation for Self-Monitoring, Analysis and Reporting Technology, a self-monitoring
system that provides indicators of drive health as well as potential disk problems. It serves as a warning
for users from unscheduled downtime by monitoring and displaying critical drive information. Ideally, this
should allow taking proactive actions to prevent drive failure and make use of S.M.A.R.T. information for
future product development reference.
Apacer devices use the standard SMART command B0h to read data out from the drive to activate our
S.M.A.R.T. feature that complies with the ATA/ATAPI specifications. S.M.A.R.T. Attribute IDs shall
include initial bad block count, total later bad block count, maximum erase count, average erase count,
power on hours and power cycle. When the S.M.A.R.T. Utility running on the host, it analyzes and reports
the disk status to the host before the device reaches in critical condition.
Note: attribute IDs may vary from product models due to various solution design and supporting
capabilities.
5.7 TRIM
TRIM is a SATA command that helps improve the read/write performance and efficiency of solid-state
drives (SSD). The command enables the host operating system to inform SSD controller whick blocks
contain invalid data, mostly because of the erase commands from host. The invalid will be discarded
permanently and the SSD will retain more space for itself.

Description of Apacer Write Protect:
Apacer implements the Virtual Write scheme that allows write commands to go through the flash
controller and data is temporarily stored, but no data has been actually written into the flash. Once the
host resets or restarts the system, all the temporarily stored data will disappear and nowhere to be found
in the drive. Since the Virtual Write scheme runs at device level, it requires no software or driver
installation and is independent from the host OS.
