1. Product Description
1.1 Introduction
Apacer’s SAFD25M4 is a solid-state disk (SSD) drive that contains a controller, embedded firmware, and flash
media along with a male connector. Using NAND flash memory devices, the SAFD drive interfaces with the
host allowing data to be seamlessly transferred between the host and the flash devices.
SAFD25M4 drive is designed with a single-chip controller, offering capacities of up to 64 gigabytes and
providing full support for the SATAⅡ high-speed interface standard. It can operate at sustained access rates
of up to 100 megabytes per second, which is much faster than any other solid-state or traditional SATA drive
currently available on the market.
In addition to buffer management through dynamical allocation, SAFD25M4 adopts the Apacer-specific global
wear-leveling scheme to allow uniform use of all storage blocks, ensuring that the lifetime of a flash media can
be significantly increased and the disk performance is optimized as well. SAFD25M4 provides the S.M.A.R.T.
feature that follows the SATA Rev. 2.6, ATA/ATAPI-7 specifications and uses the standard SMART command
B0h to read data from the drive. This feature protects the user from unscheduled downtime by monitoring and
storing critical drive performance.
Our customization services include product change notification (PCN), pre-programmed software, customize
packaging and labeling, specified testing and safety packing, depending on specific requests.
1.2 Functional Block Diagram
SAFD25M4 drive includes a single-chip SATAⅡController and the flash media, as well as the SATA standard
interface. The controller integrates the flash management unit with the controller itself to support multi-channel,
multi-bank flash arrays. Figure 1-1 shows the functional block diagram.

3. Flash Management
3.1 Error Correction/Detection
SAFD25M4 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.
3.2 Bad Block Management
Although bad blocks on the flash media are already identified by the flash manufacturer, they can also be
accumulated over time during operation. SAFD25M4’s controller maintains a table that lists those normal
blocks with disk data, the free blocks for wear leveling, and bad blocks with errors. When a normal block is
detected broken, it is replaced with a free block and listed as a bad block. When a free block is detected
broken, it is then removed from the free block list and marked as a bad block.
During device operation, this ensures that newly accumulated bad blocks are transparent to the host. The
device will stop file write service once there are only two free blocks left such that the read function is still
available for copying the files from the disk into another.
3.3 Wear Leveling
The NAND flash devices are limited by a certain number of write cycles. When using a FAT-based file system,
frequent FAT table updates are required. If some area on the flash wears out faster than others, it would
significantly reduce the lifetime of the whole SSD, even if the erase counts of others are far from the write
cycle limit. Thus, if the write cycles can be distributed evenly across the media, the lifetime of the media can
be prolonged significantly. This scheme is called wear leveling.
Apacer’s wear-leveling scheme is achieved both via buffer management and Apacer-specific wear leveling
mechanism. They both ensure that the lifetime of the flash media can be increased, and the disk access
performance is optimized as well.
3.4 Power Failure Management
The Low Power Detection on the controller initiates crucial data saving before the power supplied to the
device is too low. This feature prevents the device from crash and ensures data integrity during an
unexpected power-off.
3.5 ATA Secure Erase
Accomplished by the Secure Erase (SE) command, which added to the open ANSI standards that control disk
drives, “ATA Secure Erase” is built into the disk drive itself and thus far less susceptible to malicious software
attacks than external software utilities. It is a positive easy-to-use data destroy command, amounting to
electronic data shredding. Executing the command causes a drive to internally completely erase all possible
user data. This command is carried out within disk drives, so no additional software is required. Once
executed, neither data nor the erase counter on the device would be recoverable, which blurs the accuracy of
device lifespan. The process to erase will not be stopped until finished while encountering power failure, and
will be continued when power is back on.

3.6 S.M.A.R.T.
S.M.A.R.T. is an acronym for Self-Monitoring, Analysis and Reporting Technology, an open standard allowing
disk drives to automatically monitor their own health and report potential problems. It protects the user from
unscheduled downtime by monitoring and storing critical drive performance and calibration parameters. Ideally,
this should allow taking proactive actions to prevent impending drive failure.
Apacer SAFD25M4 uses the standard SMART command B0h to read data from the drive for SMART feature
as the SATA Rev.2.6 ATA/ATAPI-7 specifications. Based on the SFF-8035i Rev. 2.0 specifications, Apacer
SMART defines vendor-specified SMART Attribute IDs (A0h, A1h, A2h, A3h, A4h-A5h) in SAFD25M4. They
represent initial back block count, bad block count, spare block count, maximum erase count, and average
erase counts respectively. When the Apacer SMART Utility running on the host, it analyzes and reports the
disk status to the host before SAFD25M4 is in critical condition.
3.7 TRIM
Made of millions of NAND flash cells, SSD can be written into groups called pages in 4K size generally, but
can only be erased in larger groups called blocks of 128 pages or 512KB. These stipulations are partially the
source of many performance issues. Until an address gets used again, the SSD has to keep track of every
last bit of data that’s written on it. The ATA-TRIM instruction tilts the balance in favor of the SSD. TRIM
addresses a major part of the performance degradation issue over time that plagues all SSDs. A TRIM
enabled drive running an OS with TRIM support will stay closer to its peak performance over time.

4.2 Mean Time Between Failures (MTBF)
Mean Time Between Failures (MTBF) is predicted based on reliability data for the individual components in
SAFD drive. Although many component of MTBF are given in databases and often these values are not really
accurate, the prediction result for the SAFD25M4 is more than 2,000,000 hours.
Notes about the MTBF:
The MTBF is predicated and calculated based on “Telcordia Technologies Special Report, SR-332, Issue 2”
method.
