1.1 Introduction
Apacer’s Serial ATA Flash Drive (SAFD) is a solid-s tate disk (SSD) drive that contains a controller, e mbedded firmware, and flash media along with a male connect or. Using NAND flash memory devices, the drive transfers data between the host and the storage dev ices at a radical high speed, making it a great par tner for embedded systems and servers. SAFD 18P drive is designed with a single-chip contr oller, offering capacities of up to 128 gigabytes a nd providing full support for the SATA 3.0 Gbps high-s peed interface standard. It can operate at sustaine d access rates of up to higher than 260 megabytes per second, providing an ideal solution for industrial applications. In addition, SAFD 18P adopts the Apacer-specific st atic wear-leveling scheme to allow uniform use of a ll storage blocks, ensuring that the lifetime of a fla sh media can be significantly increased and the dis k ATA/ATAPI specifications and uses the standard SMAR T 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 18P 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
SAFD 18P provides ATA mode support as follows: /circle6 Up to PIO mode-4 /circle6 Up to Multiword DMA mode-2 /circle6 Up to UDMA mode-4
1.4 Capacity Specification
Capacity specification of SAFD 18P 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**
8 GB 7,012,196,352 13,587 16 63 13,695,696
16 GB 16,013,942,784 16383 16 63 31,277,232
32 GB 32,017,047,552 16,383 16 63 62,533,296

128 GB 128,035,676,10 16383 16 63 250,069,60
*Display of total bytes varies from file systems. 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.
1.5 Performance
Performance of SAFD 18P is shown in Table 1-2. Table 1-2 Performance specifications Capacity Performance 8 GB 16 GB 32 GB 64 GB 128 GB Sustained Read (MB/s) 255 260 260 260 245 Sustained Write (MB/s) 100 205 190 215 165 Note: Performances vary from flash configurations and host system configurations. Read/write performance is measured using CrystalDiskMark under Windows XP operating sytem.

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
SAFD 18P implements hardware ECC scheme based on th e 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 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. 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 b e 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 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.
