Rev. 1.3 SATA-Disk Module 4 APSDMxxxxG5AN-PXXX 1. General Description Apacer's SATA-Disk Module 4 (SDM4) is a high-performance, embedded SSD DOM (Disk on Module) designed to replace the conventional SATA storage devices. SDM4 can be fitted into a standard Serial ATA connectors commonly found in desktops, IT-STB, industrial PC and thin client systems. In addition, SDM4 provides an innovative way for design-in clients with compact host computing systems. Apacer's SDM4 is built in with an efficient microcontroller that drives the potential of NAND flash and delivers optimal performance. With its compact form factor and SATA 3.0 Gbps interface, this product is well suited for embedded flash storage applications offering customizable and expanded functionalities as well as more cost-effective designs, better performance and increased reliability. 2. Functional Block SDM4 includes the SATA and Flash Management controllers, and flash media, as well as the SATA standard interface. Figure 2-1 shows the functional block diagram.

Product Specification 4.1 Capacity Capacity specification of SDM4 product family is available as shown in Table 4-1. It lists the specific capacity and the default numbers of heads, sectors and cylinders for each product line. Table 4-1: Capacity specifications Capacity Total bytes Cylinders Heads Sectors Max LBA 2 GB 2,011,226,112 3,897 16 63 3,928,176 4 GB 4,011,614,208 7,773 16 63 7,835,184 8 GB 8,012,390,400 15,525 16 63 15,649,200 16 GB 16,013,942,784 16,383 16 63 31,277,232 32 GB 32,017,047,552 16,383 16 63 62,533,296 Notes: Display of total bytes varies from file systems, which means not all of the bytes can be used for storage. 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. 4.2 Performance Performances of SDM4 are listed below in table 4-2.

The prediction result for SDM4 is more than 2,000,000 hours. Notes about the MTBF: The MTBF is predicated and calculated based on "Telcordia Technologies Special Report, SR-332, Issue 2" method. 4.5 Certification and Compliance SDM4 complies with the following standards: CE FCC RoHS MIL-STD-810 7 (c) 2013 Apacer Technology Inc. Rev. 1.3 SATA-Disk Module 4 APSDMxxxxG5AN-PXXX 5. Flash Management 5.1 Error Correction/Detection SDM4 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. 5.2 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. 5.3 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. 5.4 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. 5.5 ATA Secure Erase AATA 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. 8 (c) 2013 Apacer Technology Inc. Rev. 1.3 SATA-Disk Module 4 APSDMxxxxG5AN-PXXX 5.6 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. 5.7 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. 9 (c) 2013 Apacer Technology Inc. Rev. 1.3 SATA-Disk Module 4 APSDMxxxxG5AN-PXXX 6. Software Interface 6.1 Command Set This section defines the software requirements and the format of the commands the host sends to SDM4.

Once the host resets or restarts the system, all the temporarily stored data will disappear and nowhere to be found in the drive. Since the Virtual Write scheme runs at device level, it requires no software or driver installation and is independent from the host OS. 14 (c) 2013 Apacer Technology Inc.
