1. Product Description

1.1 Introduction

Apacer’s Serial ATA Flash Drive (SAFD) is a standard 2.5-inch solid-state drive (SSD) designed for

embedded applications in demanding environments. SAFD 25P drive is designed with a single-chip controller

providing full support for the SATA II high-speed interface standard. It can operate at sustained access rates

up to 260 megabytes per second.

In addition, SAFD 25P adopts the global wear-leveling scheme to allow uniform use of all storage blocks,

ensuring that the lifespan of a flash media can be significantly increased and the disk performance is

optimized as well. SAFD 25P 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

SAFD 25P drive includes a single-chip SATA II 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.

1.4 Capacity Specification

Capacity specification of SAFD 25P product family is available as shown in Table 1-1. It lists the specific

**Cylinders, heads or sectors are not applicable for these capacities. Only LBA addressing applies.

***Notes: 1 GB = 1,000,000,000 bytes; 1 sector = 512 bytes.

LBA count addressed in the table above indicates total user storage capacity and will remain the same throughout the lifespan of

the device. However, the total usable capacity of the SSD is most likely to be less than the total physical capacity because a small

portion of the capacity is reserved for device maintenance usages.

2.2 S.M.A.R.T.

S.M.A.R.T. is an abbreviation for Self-Monitoring, Analysis and Reporting Technology, a self-monitoring

system that provides indicators of drive health as well as potential disk problems. It serves as a warning for

users from unscheduled downtime by monitoring and displaying critical drive information. Ideally, this should

allow taking proactive actions to prevent drive failure and make use of S.M.A.R.T. information for future

product development reference.

Apacer devices use the standard SMART command B0h to read data out from the drive to activate our

S.M.A.R.T. feature that complies with the ATA/ATAPI specifications. S.M.A.R.T. Attribute IDs shall include

initial bad block count, total later bad block count, maximum erase count, average erase count, power on

hours and power cycle. When the S.M.A.R.T. Utility running on the host, it analyzes and reports the disk

status to the host before the device reaches in critical condition.

Note: attribute IDs may vary from product models due to various solution design and supporting capabilities.

3. Flash Management

3.1 Error Correction/Detection

SAFD 25P implements hardware ECC scheme based on the BCH algorithm which can detect and correct up

to 16 bits or 24 bits error in 1024 bytes.

3.2 Flash Block Management

Current production technology is unable to guarantee total reliability of NAND flash memory array. When a

flash memory device leaves factory, it comes with a minimal number of initial bad blocks during production or

out-of-factory as there is no currently known technology that produce flash chips free of bad blocks. In addition,

bad blocks may develop during program/erase cycles. When host performs program/erase command on a

block, bad block may appear in Status Register. Since bad blocks are inevitable, the solution is to keep them

in control. Apacer flash devices are programmed with ECC, block mapping technique and S.M.A.R.T to

reduce invalidity or error. Once bad blocks are detected, data in those blocks will be transferred to free blocks

and error will be corrected by designated algorithms.

3.3 Wear Leveling

Flash memory devices differ from Hard Disk Drives (HDDs) in terms of how blocks are utilized. For HDDs,

when a change is made to stored data, like erase or update, the controller mechanism on HDDs will perform

overwrites on blocks. Unlike HDDs, flash blocks cannot be overwritten and each P/E cycle wears down the

lifespan of blocks gradually. Repeatedly program/erase cycles performed on the same memory cells will

eventually cause some blocks to age faster than others. This would bring flash storages to their end of service

term sooner. Wear leveling is an important mechanism that level out the wearing of blocks so that the

wearing-down of blocks can be almost evenly distributed. This will increase the lifespan of SSDs. Commonly

used wear leveling types are Static and Dynamic.

3.4 Power Failure Management

Power Failure Management plays a crucial role when experiencing unstable power supply. Power disruption

may occur when users are storing data into the SSD. In this urgent situation, the controller would run multiple

write-to-flash cycles to store the metadata for later block rebuilding. This urgent operation requires about

several milliseconds to get it done. At the next power up, the firmware will perform a status tracking to retrieve

the mapping table and resume previously programmed NAND blocks to check if there is any incompleteness

of transmission.

Note: The controller unit of this product model is designed with a DRAM as a write cache for improved performance and data efficiency.

Though unlikely to happen in most cases, the data cached in the volatile DRAM might be potentially affected if a sudden power loss takes

place before the cached data is flushed into non-volatile NAND flash memory.

3.5 ATA Secure Erase

ATA Secure Erase is an ATA disk purging command currently embedded in most of the storage drives.

Defined in ATA specifications, (ATA) Secure Erase is part of Security Feature Set that allows storage drives to

erase all user data areas. The erase process usually runs on the firmware level as most of the ATA-based

storage media currently in the market are built-in with this command. ATA Secure Erase can securely wipe out

the user data in the drive and protects it from malicious attack.

Rev. 2.0

Serial ATA Flash Drive

APS25P6Bxxxx- 5XX

3.6 TRIM

TRIM, though in capital letters usually, is a memory computation command rather than an abbreviation. It is

mainly a SATA command that enables the operating system to inform the SSD (Solid State Drive) which

blocks of previously stored data are no longer valid, due to erases by the host or operating system, such as

file deletions or disk formatting. Once notified, SSD will begin the discard of the invalid LBAs and retain more

space for itself, in fact, the discarded is no longer recoverable.

When an LBA is replaced by the operating system, as with overwrite of a file, the SSD is informed that the

originally occupied LBA is determined as no longer in use or invalid. The SSD will not save those blocks in

garbage collected sectors. Noticeably, a file deletion command by host or operating system never actually

erases the actual content, rather, just the file is marked as deleted. This issue is even specifically noticeable

for flash based memory devices, such as SSDs. In fact, an SSD will keep garbage collecting the invalid,

previously occupied LBAs, if it is not informed that these LBAs can be erased. Thus, the SSD would

experience a significant performance downfall.

4.4 Endurance

Terabytes Written (TBW) is an endurance rating system that indicates the maximum number of terabytes

written by the host to the drive. NAND flash has a limit on how many P/E cycles it can withstand before its

data retention becomes unreliable. Thus, key factors, such as wear leveling, flash configurations, Write

Amplifications and the number of P/E cycles, can influence the lifespan of the drive.

The TBW of the device are listed in the following table.

Notes:

The measurement assumes the data written to the SSD for test is under a typical and constant rate.

The measurement follows the standard metric: 1 TB (Terabyte) = 1000 GB.
