1. Product Description
1.1
Introduction
Apacer’s SDMⅡ M1 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.
The SDMⅡ M1 drive is designed with a single-chip controller, offering capacities of up to 32 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, the SDMⅡ M1 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. The SDMⅡ M1 provides
the S.M.A.R.T. feature that follows the SATA Rev. 2.5, 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.
1.2
Functional Block Diagram
The SDMⅡ M1 drive includes a single-chip SATAⅡ Controller 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
The SDMⅡ M1 implements a hardware ECC scheme, based on the BCH algorithm, to achieve up to 8/15 bit
correction per 512 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. The SDMⅡ M1’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 global wear
leveling. 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 cached data saving before the power supply to the device
is too low. This feature prevents the device from crash and ensures data integrity during an unexpected
blackout. Once power was failure before cached data writing back into flash, data in the cache will lost. The
next time the power is on, the controller will check these fragmented data segment, and, if necessary, replace
them with old data kept in flash until programmed successfully.
3.5
Quick Erase
Accomplished by the Secure Erase (SE) command, which added to the open ANSI standards that control disk
drives, “Quick 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. Technology
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 SMART feature follows the SATA Rev. 2.5, ATA/ATAPI-7 specifications, using the standard SMART
command B0h to read data from the drive. And based on the SFF-8035i Rev. 2.0 specifications, Apacer
SMART defines 3 vendor-specified SMART Attribute IDs (E5h, E8h-EFh, and F3h) in the SDMⅡ M1. They
represent Flash ID, good block count, free-list block count, maximum erase count, average erase count, and
firmware version information. When the Apacer SMART Utility running on the host, it analyzes and reports the
disk status to the host before the SDMⅡ M1 is in critical condition.
