1. Product Description
1.1
Introduction
Apacer’s SATA Disk Module (SDM) 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 SDM drive
interfaces with the host allowing data to be seamlessly transferred between the host and the flash devices.
The SDM drive is designed with a single-chip controller, offering capacities of up to four gigabytes and
providing full support for the SATAⅡ high-speed interface standard. It can operate at sustained access rates
of up to thirty five megabytes per second, which is much faster than any other competitor in the market.
In addition to buffer management through dynamical allocation, the SDM adopts the static 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 SDM provides the S.M.A.R.T.
feature complies to 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.
1.2
Functional Block Diagram
The SDM 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 SDM implements a hardware ECC scheme, based on the BCH algorithm. It can detect and correct up to
8 bits or 15 bits error in 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 SDM’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 static 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 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.

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 SDM 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 3 vendor-specified SMART Attribute IDs (E5h, EAh-EBh, and E8h) in the SDM. They represent Flash
ID, maximum erase count, average erase count, good block count, free-list block 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 SDM is in critical condition.
