PCI-Express SSD
APPXXXXXXA-AXX
1. General Description
Apacer’s mPDM+ (mini PCIe Disk Module Plus) SSD offers a breakthrough in non-volatile memory
storage. Formed as a mini PCI-Express card, this mPDM+ can fit in various types of embedded platforms,
such as workstation, thin computing devices and high-end heavy duty servers where spaces are
concerned. Regarding data transfer rate, mPDM+ delivers ideal data read/write performance.
Apacer mPDM+ provides one-lane PCI-Express 2.0 host interface, and is compatible with 5.0 Gbps
maximum transfer rate. Compatibility wise, this mini PCIe SSD is not only fully compliant with PCI
Express Specification Rev.2.0 and Electromechanical Rev.2.0, but also supports NCQ commands and
IDE/AHCI operational modes.
1.1 Error Correction/Detection
The ECC engine in this device can detect and correct up to 72 bits error in 1K bytes.
1.2 Flash Block Management
Bad blocks are blocks that include one or more invalid bits, and their reliability is not guaranteed. Blocks
that are identified and marked as bad by the manufacturer are referred to as “Initial Bad Blocks”. Bad
blocks that are developed during the lifespan of the flash are named “Later Bad Blocks”. Thus, this device
implements an efficient bad block management algorithm to detect the factory-produced bad blocks and
manages any bad blocks that appear with use. This practice further prevents data being stored into bad
blocks and improves the data reliability.
1.3 Wear Leveling
NAND Flash devices can only undergo a limited number of program/erase cycles, and in most cases, the
flash media are not used evenly. If some area get updated more frequently than others, the lifetime of the
device would be reduced significantly. Thus, Wear Leveling technique is applied to extend the lifespan of
NAND Flash by evenly distributing write and erase cycles across the media. Apacer provides advanced
Wear Leveling algorithm, which can efficiently spread out the flash usage through the whole flash media
area. Moreover, by implementing both dynamic and static Wear Leveling algorithms, the life expectancy
of the NAND Flash is greatly improved.
1.4 Power Failure Management
Power Loss Protection is a mechanism to prevent data loss during unexpected power failure. DRAM is a
volatile memory and frequently used as temporary cache or buffer between the controller and the NAND
flash to improve the SSD performance. However, one major concern of the DRAM is that it is not able to
keep data during power failure. Accordingly, the module applies the flushing mechanism which requests
the controller to transfer data to the cache. For this flash module, SDR performs as a cache, and its sizes
include 8MB or 32MB. Only when the data is fully committed to the NAND flash will the controller send
acknowledgement to the host. Such implementation can prevent false-positive performance and the risk
of power cycling issues.
Additionally, it is critical for a controller to shorten the time the in-flight data stays in the cache. Thus, the
module applies an algorithm to reduce the amount of data resides in the cache to provide a better

performance by allowing incoming data to only have a “pit stop” in the cache and then move to the NAND
flash at once. If the flash is jammed due to particular file sizes (random 4K), the cache will be treated as
an “organizer”, consolidating incoming data into groups before written into the flash to improve write
amplification.
In sum, with this power failure management, this module proves to provide the reliability required by
consumer, industrial, and enterprise-level application.
1.5 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.
1.6 S.M.A.R.T.
SMART, an acronym for Self-Monitoring, Analysis and Reporting Technology, is an open standard that
allows a hard disk drive to automatically detect its health and report potential failures. When a failure is
recorded by SMART, users can choose to replace the drive to prevent unexpected outage or data loss.
Moreover, SMART can inform users of impending failures while there is still time to perform proactive
actions, such as copy data to another device.

*Display of total bytes varies from file systems.
**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 mPDM+ 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.
