Product Description 1.1 Introduction Apacer’s SAFD25M4-M 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 transferred between the host and the flash devices. SAFD25M4-M drive is designed with a single-chip controller, offering capacities of up to 128 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. Though built with MLC, this SSD can work in highly demanding environment as it can withstand ambient temperature from -40°C to +85°C (for certain capacities only). In addition to buffer management through dynamical allocation, SAFD25M4-M 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. SAFD25M4-M 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. Our customization services include product change notification (PCN), pre-programmed software, customize packaging and labeling, specified testing and safety packing, depending on specific requests. 1.2 Functional Block Diagram SAFD25M4-M drive includes a single-chip SATAⅡ 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.

Rev. 1.1 Serial ATA Flash Drive APS25M5Axxxx-ACMX 3. Flash Management 3.1 Error Correction/Detection SAFD25M4-M 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. SAFD25M4-M’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 block. 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 wear leveling mechanism. 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. 8 © 2011 Apacer Technology Inc. Rev. 1.1 Serial ATA Flash Drive APS25M5Axxxx-ACMX 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 proactive actions to prevent impending drive failure. Apacer SAFD25M4-M 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 SAFD25M4M. 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 SAFD25M4-M 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 time. 9 © 2011 Apacer Technology Inc. Rev. 1.1 Serial ATA Flash Drive APS25M5Axxxx-ACMX 4. Environmental Specifications 4.1 Environments SAFD25M4-M environmental specifications follow the US Military Standard MIL-STD-810F, as shown in below table.
