1. General Descriptions
Apacer’s SDM5A (SATA Disk Module 5A) is our next generation disk-on-module (DOM) series that
offers elevated speed boost and higher error correction capabilities. Built with SATA 6.0 Gb/s
interface, SDM5A delivers higher performance in data transfer than its previous SDM selections,
reaching up to 90 MB/s in read and 75 MB/s in write.
With its SATA interface compliance and compact size, this high-speed disk module defines an ideal
balance of performance, capacities, reliability and cost. SDM5A comes in moderate capacities that
are suitable to boot industrial applications and light operating systems for specific operations, while
with some extra memory space for data storage. The architectural nature of SATA disk module
provides higher resistance to external environmental influences and better flexibility for motherboard
space.
Regarding data reliability, SDM5A is built in with powerful ECC engine that can correct up to 40 bits
per 1KB data. In addition, the controller unit of this DOM device supports wear-leveling, SMART and
power failure management for data integrity. With its trustable reliability, performance and cost
effectiveness, Apacer’s SDM5A is definitely the ideal storage or cache solution for embedded and
industrial computers, servers and thin clients.
2. Functional Block
SDM5A includes the SATA and Flash Management controllers, and flash media, as well as the SATA
standard interface. Figure 2-1 shows the functional block diagram.

*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.

4.4 Mean Time Between Failures (MTBF)
Mean Time Between Failures (MTBF) is predicted based on reliability data for the individual
components in SDM5A. The prediction result for SDM5A is more than 2,000,000 hours.
Note: The MTBF is predicated and calculated based on “Telcordia Technologies Special Report, SR332, Issue 2” method.
4.5 Certification and Compliance

5. Flash Management
5.1 Error Correction/Detection
SDM5A implements a hardware ECC scheme, based on the BCH algorithm. It can detect and correct
up to 40 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 Global 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. Global wear leveling is an important
mechanism that levels out the wearing of all blocks so that the wearing-down of all blocks can be
almost evenly distributed. This will increase the lifespan of SSDs.
5.4 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.
5.5 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.

6.1 Command Set

6.2 S.M.A.R.T.
S.M.A.R.T. is an abbreviation for Self-Monitoring, Analysis and Reporting Technology, a selfmonitoring 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.

Apacer memory products come with S.M.A.R.T. commands and subcommands for users to obtain
information of drive status and to predict potential drive failures. Users can take advantage of the
