SATA-Disk Module 4

1. General Description
Apacer’s SATA-Disk Module 4 (SDM4) is a high-performance, embedded SSD designed to replace the
conventional SATA hard disk drive. SDM SSD can be plugged into a standard Serial ATA connectors
commonly found in desktops, IT-STB, industrial PC and thin client systems. Moreover, SDM4 provides an
innovative way for design-in clients with compact host systems.
Apacer’s SDM4 has a built-in microcontroller with file management firmware that communicates with
SATA standard interface. This product is well suited for embedded flash storage applications offering new
and expanded functionalities as well as more cost-effective designs, better performance and increased
reliability.
SDM4 Series is designed to work at 5 Volts and uses a standard SATA driver that complies with major
operating systems such as Microsoft’s Windows series. Featuring technologies as Apacer-specific Wearleveling algorithms, S.M.A.R.T, bad block management, Power Failure Management, ATA Secure Erase,
and TRIM, Apacer assures users of a versatile device on data storage.
This SDM4 SSD is designed to be rugged for industrial applications where harsh, demanding
environments are often encountered, and has gone through environmental testings such as shock, wide
temperature range and ESD. Our SSDs meet international standards and we specialized in customization
services in both hardware and systems.

1.1 Performance-Optimized Controller
The heart of SDM4 is the Flash controller, which translates standard SATA signals into the data and
controls of the flash media. The SATA and Flash Management controller are specifically designed to
attain high data throughput from the host to the flash.
1.1.1 Power Management
The controller comes with SATA physical interface (PHY) that takes a significant part of the total power
budget of the host or other connected electronics. SATA interface provides the means to place the PHY
into lowered power modes. When the parts of power for PHY are shut down to reserve power supply, the
ability of the SATA interfaced device to respond to command can be affected. Thus, the SATA protocol is
implemented with the capability to track the power modes of the devices and require the additional
latency to wake up PHY from lowered power modes.
1.1.2 RAM
The controller is implemented with RAM as a data buffer to optimize data transfer between the host and
the flash media.

*Display of total bytes varies from file systems, which means not all of the bytes can be used for storage.
**Notes: 1 GB = 1,000,000,000 bytes; 1 sector = 512 bytes.
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 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 Bad 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
ATA 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.

APSDMxxxx15XX-PXX
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, though in capital letters usually, is a memory computation command rather than an abbreviation. It
is mainly a SATA command that enables the operating system to inform the SSD (Solid State Drive)
which blocks of previously stored data are no longer valid, due to erases by the host or operating system,
such as file deletions or disk formatting. Once notified, SSD will begin the discard of the invalid LBAs and
retain more space for itself, in fact, the discarded is no longer recoverable.
When an LBA is replaced by the operating system, as with overwrite of a file, the SSD is informed that the
originally occupied LBA is determined as no longer in use or invalid. The SSD will not save those blocks
in garbage collected sectors. Noticeably, a file deletion command by host or operating system never
actually erases the actual content, rather, just the file is marked as deleted. This issue is even specifically
noticeable for flash based memory devices, such as SSDs. In fact, an SSD will keep garbage collecting
the invalid, previously occupied LBAs, if it is not informed that these LBAs can be erased. Thus, the SSD
would experience a significant performance downfall.

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