1.1 Introduction

Apacer’s Serial ATA Flash Drive (SAFD) is a non-vol atile SATA solid-state drive (SSD) that serves as t he ideal boot drive or mass storage device. Compliant with SATA 3.0 Gbps standard, the drive conforms to most mainstream host system platforms with SATA-complian t interfaces, making it the primary storage solutio n for replacing traditional hard disk drive. SAFD 25M4 drive is designed with a powerful control ler, offering capacities of up to 64 gigabytes and providing full support for the SATA 3.0 Gbps high-s peed interface standard. It can operate at sustaine d access rates up to 165 megabytes per second, while power consumption remains at minimal level. Regardi ng data integrity and memory efficiency, the controlle r unit of the device handles wear leveling, ECC, ba d block management and power management in urgent situations. In addition, SAFD 25M4 adopts the global wear-level ing scheme to allow uniform use of all storage bloc ks, ensuring that the lifespan of a flash media can be significantly increased and the disk performance is specifications and uses the standard SMART command B0h to read data from the drive. This feature prote cts the user from unscheduled downtime by monitoring an d storing critical drive performance.

1.2 Functional Block Diagram

SAFD25M4 drive includes a single-chip SATA Controll er and the flash media, as well as the SATA standar d interface. The controller integrates the flash mana gement unit with the controller itself to support m ulti-channel, multi-bank flash arrays. Figure 1-1 shows the functional block diagram.

1.3 ATA Mode Support

SAFD25M4 provides ATA mode support as follows: /circle6 Up to PIO mode-4 /circle6 Up to Multiword DMA mode-2 /circle6 Up to UDMA mode-5

1.4 Capacity Specification

Capacity specification of SAFD25M4 product family i s available as shown in Table 1-1. It lists the spe cific capacity, the default numbers of logical cylinders and heads, and the number of logical sectors per tr ack for each product line. Table 1-1 Capacity specification Capacity Total Bytes* Cylinders Heads Sectors Max LBA*

4 GB 4,011,614,208 7,773 16 63 7,835,184

*Display of total bytes varies from file systems. **Cylinders, heads or sectors are not applicable for these capacities. Only LBA addressing applies. 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.

It serves as a war ning for users from unscheduled downtime by monitoring and d isplaying critical drive information. Ideally, this should product development reference. Apacer devices use the standard SMART command B0h t o read data out from the drive to activate our initial bad block count, total later bad block coun t, maximum erase count, average erase count, power on 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 capabil ities.

3.1 Error Correction/Detection

SAFD25M4 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

Current production technology is unable to guarante e total reliability of NAND flash memory array. Whe n a flash memory device leaves factory, it comes with a minimal number of initial bad blocks during produc tion or out-of-factory as there is no currently known techn ology 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. Sin ce bad blocks are inevitable, the solution is to ke ep them reduce invalidity or error. Once bad blocks are det ected, 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 perf orm overwrites on blocks. Unlike HDDs, flash blocks can not be overwritten and each P/E cycle wears down th e lifespan of blocks gradually. Repeatedly program/er ase cycles performed on the same memory cells will eventually cause some blocks to age faster than oth ers. This would bring flash storages to their end o f service term sooner. Wear leveling is an important mechanis m that level out the wearing of blocks so that the wearing-down of blocks can be almost evenly distrib uted. This will increase the lifespan of SSDs. Comm only 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 disruptio n 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 lat er block rebuilding. This urgent operation requires about several milliseconds to get it done. At the next po wer 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.

3.5 ATA Secure Erase

ATA Secure Erase is an ATA disk purging command cur rently embedded in most of the storage drives. Defined in ATA specifications, (ATA) Secure Erase i s part of Security Feature Set that allows storage drives to erase all user data areas. The erase process usuall y runs on the firmware level as most of the ATA-bas ed storage media currently in the market are built-in with this command. ATA Secure Erase can securely wi pe out the user data in the drive and protects it from mal icious attack.

3.6 TRIM

TRIM, though in capital letters usually, is a memor y computation command rather than an abbreviation. It is mainly a SATA command that enables the operating sy stem to inform the SSD (Solid State Drive) which blocks of previously stored data are no longer vali d, due to erases by the host or operating system, s uch as file deletions or disk formatting. Once notified, S SD will begin the discard of the invalid LBAs and r etain 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 bloc ks in garbage collected sectors. Noticeably, a file delet ion command by host or operating system never actua lly 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 fa ct, an SSD will keep garbage collecting the invalid , previously occupied LBAs, if it is not informed tha t these LBAs can be erased. Thus, the SSD would experience a significant performance downfall.

SAFD25M4 complies with the following standards: /circle6 CE /circle6 FCC /circle6 RoHS /circle6 MIL-STD-810F

4.4 Endurance

The endurance of a storage device is predicted by T eraBytes Written based on several factors related t o usage, such as the amount of data written into the drive, block management conditions, and daily workl oad for the drive. Thus, key factors, such as flash configu ration, wear leveling, Write Amplifications and the number of P/E cycles, can influence the lifespan of the drive. Capacity TeraBytes Written

6.2 Write Protect Switch (optional)

Description of Apacer Write Protect: Apacer implements the Virtual Write scheme that allows write commands to go through the flash controller and data temporarily stored. The OS can then function normally but no data has been actually written into the flash. Since the Virtual Write scheme runs at device level, it requires no software or driver installation and is independent from the host OS. Write Protect switch Enable Disable
