1. Product Description

1.1 Introduction

Apacer’s SAFD18S4 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 tran sferred between the host and the flash devices.

SAFD18S4 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, SAFD18S4 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 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 drive includes a single-chip SATA ⅡController 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

SAFD18S4 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’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 blo c k.

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.

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 pro active actions to prevent impending drive failure.

Apacer SAFD18S4 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 SAFD18S4. 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 SAFD18S4 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 ti me.
