CFast 2H-M
APCFAxxxGBAN-XFTM1
1. General Description
Apacer CFast 2H-M is the latest enhancement of conventional CFast form factor that delivers various
technological advantages. This new flash memory card comes with SATA 6.0 Gbps interface for higher
performance and is compliant with standard CFast specifications. CFast 2H-M consists of SATA-based 7pin signal segment and 17-pin for power and control purposes. It can offer moderate capacity and decent
data transfer performance. For power efficiency, this new flash memory card leverages the technological
benefits of SATA Revision 3.0 specifications. For data integrity, the CFast card is built with ECC engine
correcting up to 72-bit. Together with its small form factor nature, Apacer CFast 2H-M is definitely the
ideal solution to replace conventional PATA-based CompactFlash for applications in industrial computing
systems, mobile computers and video processing instruments.
2. Functional Block
Apacer CFast 2H-M includes a single-chip SATA 6.0 Gbps and the flash media. The controller integrates
the flash management unit to support multi-channel, multi-bank flash arrays. Figure 2-1 shows the
functional block diagram.

**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 CFast-M 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
Flash memory cells will deteriorate with use, which might generate random bit errors in the stored data.
Thus, the CFast-M applies the BCH ECC Algorithm, which can detect and correct errors up to 72-bit in 1K
byte data during Read process, ensure data been read correctly, as well as protect data from corruption.
5.2 Bad 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”. Apacer
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.
5.3 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 areas 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.
5.4 Power Failure Management
Power Failure Management is a mechanism to prevent data loss during unexpected power failure. When
power outage occurs, the data that has not been written into NAND Flash is in risk. Thus, the purpose of
this mechanism is to request the controller to transfer data to the cache. In this CFast-M 2.0 structure,
SDR performs as a cache, and its sizes is 32MB. Only when the data is fully committed to the NAND flash
will the controller send acknowledgement (ACK) to the host. Such implementation can prevent falsepositive 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, this
CFast 2H-M memory card applies an algorithm to reduce the amount of data resides in the cache to
provide a better performance. This allows 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.

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.
5.6 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.
5.7 TRIM
TRIM is a feature which helps improve the read/write performance and speed of Solid-State Drives (SSD).
Unlike Hard Disk Drives (HDD), SSDs are not able to overwrite existing data, so the available space
gradually becomes smaller with each use. With the TRIM command, the operating system can inform the
SSD which blocks of data are no longer in use and can be removed permanently. Thus, the SSD will
perform the erase action, which prevents unused data from occupying blocks all the time.
5.8 Endurance
The endurance of a storage device is predicted by TeraBytes Written based on several factors related to
usage, such as the amount of data written into the drive, block management conditions, and daily
workload for the drive. Thus, key factors, such as Write Amplifications and the number of P/E cycles, can
influence the lifespan of the drive.

Notes:
The measurement assumes the data written to the SSD for test is under a typical and constant rate.
The measurement follows the standard metric: 1 TB (Terabyte) = 1,000 GB.
This estimation complies with JEDEC JESD-219, enterprise endurance workload of random data
with payload size distribution.
