sata-disk module ap-sdmxxxx1paxs-ht 4 ? 2011 apacer technology inc. rev. 1.3 1. product description 1.1 introduction apacers sata disk module (sdm) is a solid-state di sk (ssd) drive that contains a controller, embedded firmware, and flash media along with a male connect or. using nand flash memory devices, the sdm drive interfaces with the host allowing data to be seamle ssly transferred between the host and the flash dev ices. the sdm drive is designed with a single-chip contr oller, offering capacities of up to 16 gigabytes an d providing full support for the sata high-speed interface standard. it can operate at s ustained access rates of up to thirty five megabytes per second, which is much faster than any other competitor in the marke t. in addition to buffer management through dynamical allocation, the sdm adopts the static 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. the sdm provides the s.m.a.r.t. feature complies with the sata rev. 2.6, ata/atapi- 7 specifications and uses the standard smart command b0h to read data from the drive. this featu re protects the user from unscheduled downtime by monitoring and storing critical drive performance. 1.2 functional block diagram the sdm drive includes a single-chip sata controller and the flash media, as well as the sat a standard 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 funct ional block diagram. figure 1-1 apacer sdm block diagram

sata-disk module ap-sdmxxxx1paxs-ht 25 ? 2011 apacer technology inc. rev. 1.3 3. flash management 3.1 error correction/detection the sdm implements a hardware ecc scheme, based on the bch algorithm, to achieve up to 8/15 bit correction per 512 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. the control ler of sdm maintains a table that lists those norma l blocks with disk data, the free blocks for wear lev eling, and bad blocks with errors. when a normal bl ock is detected broken, it is replaced with a free block a nd listed as a bad block. when a free block is dete cted broken, it is then removed from the free block list and marked as a bad block. during device operation, this ensures that newly ac cumulated bad blocks are transparent to the host. t he device will stop file write service once there are only two free blocks left such that the read functi on 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 num ber of write cycles. when using a fat-based file sy stem, frequent fat table updates are required. if some ar ea on the flash wears out faster than others, it wo uld significantly reduce the lifetime of the whole ssd, even if the erase counts of others are far from th e write cycle limit. thus, if the write cycles can be distr ibuted evenly across the media, the lifetime of the media can be prolonged significantly. this scheme is called w ear leveling. apacers wear-leveling scheme is achieved both via buffer management and apacer-specific global wear leveling. 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 cached data saving before the power supply to the device is too low. this feature prevents the device from c rash and ensures data integrity during an unexpecte d blackout. once power was failure before cached data writing back into flash, data in the cache will lo st. the next time the power is on, the controller will chec k these fragmented data segment, and, if necessary, replace them with old data kept in flash until programmed s uccessfully. 3.5 quick erase accomplished by the secure erase (se) command, whic h added to the open ansi standards that control dis k drives, quick erase is built into the disk drive itself and thus far less susceptible to malicious s oftware attacks than external software utilities. it is a p ositive easy-to-use data destroy command, amounting to electronic data shredding. executing the command ca uses a drive to internally completely erase all pos sible 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 accur acy of
sata-disk module ap-sdmxxxx1paxs-ht 26 ? 2011 apacer technology inc. rev. 1.3 device lifespan. the process to erase will not be s topped until finished while encountering power fail ure, and will be continued when power is back on. 3.6 s.m.a.r.t. s.m.a.r.t. is an acronym for self-monitoring, analy sis and reporting technology, an open standard allo wing disk drives to automatically monitor their own heal th and report potential problems. it protects the u ser from unscheduled downtime by monitoring and storing crit ical drive performance and calibration parameters. ideally, this should allow taking proactive actions to preve nt impending drive failure. apacer smart feature follows the sata rev. 2.5, ata /atapi-7 specifications, using the standard smart command b0h to read data from the drive. and based on the sff-8035i rev. 2.0 specifications, apacer smart defines 3 vendor-specified smart attribute id s (e5h, e8h-efh, and f3h) in the sdm. they represent flash id, good block count, free-list blo ck count, maximum erase count, average erase count, and firmware version information. when the apacer smart utility running on the host, it analyzes and repor ts the disk status to the host before the sdm is in critic al condition.
