1. Product Description
1.1 Introduction
Apacer’s SAFD18S4-M 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.
SAFD18S4-M drive is designed with a single-chip controller, offering capacities of up to 128 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. Though built with MLC, this SSD can work in highly demanding
environment as it can withstand ambient temperature from -40°C to +85°C (for certain capacities only).
In addition to buffer management through dynamical allocation, SAFD18S4-M 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. SAFD18S4-M 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.
1.2
Functional Block Diagram
SAFD18S4-M 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.

2.2 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 devices use the standard SMART command B0h to read data out from the drive to activate our SMART
feature that complies with the ATA/ATAPI-7 specifications. Based on the SFF-8035i Rev. 2.0 specifications,
Apacer SMART defines vendor-specified SMART Attribute IDs (A0 ~ A5, and 0C). They represent Initial bad
block count, Bad block count, Spare block count, Maximum erase count, Average erase count and Power cycle.
When the Apacer SMART Utility running on the host, it analyzes and reports the disk status to the host before
the device reaches in critical condition.

3. Flash Management
3.1
Error Correction/Detection
SAFD18S4-M 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. SAFD18S4-M’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
Power Failure Recovery ensures data transmission when experiencing unstable power supply. When power
disruption takes places, NAND Flash will have to cache multiple write-to-flash cycles to securely store data.
This urgent operation requires about several milliseconds to get it done. When the supplied voltage is below a
certain percentage of the required, the flash controller will be signaled by a detector IC component with low
power detection signal and then the firmware will communicate the controller to flush all the data into the cache
of Flash storage area. This can prevent incomplete data transmission.
The crucial part lies in the strength of the capacitor of the SSD. The capacitor must be able to hold up some
milliseconds of remaining time before the power is totally out, for the urgent write-back-into-flash operations to
complete.
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
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 SAFD18S4-M is more than 1,000,000 hours.
Notes about the MTBF:
The MTBF is predicated and calculated based on “Telcordia Technologies Special Report, SR-332, Issue 2”
method.
