ata flash drive ap-fd18a20cxxxxxs-xxx 3 ? 2011 apacer technology inc. rev. 1.0 1. general description apacers ata-flash drive (afd) is a high-performanc e, solid state drive (ssd) designed to replace a conventional ide hard disk drive. afd supports stan dard ata/ide protocol and can be plugged into a zif connector commonly found in portable pcs. it is mor e rugged, reliable and power-efficient compared to the mechanical hard drive and is designed for use i n rugged laptops, military devices, thin clients, p oint of sale (pos) terminals, telecom, medical instruments, surveillance systems and industrials pcs. apacer afd series is the best drop-in replacement for high -maintenance hdd where reliability is a major concern. afd includes a built-in microcontroller and file ma nagement firmware that communicates through with th e ata standard interfaces and is set to the master op eration in default. this means the afd does not require any additional or proprietary host software such as the flash file system (ffs) and memory technology driver (mtd) software. afd is designed t o work at 3.3 volts, support the standard ata/ide protocol up to pio mode-4, multiword dma mode-2, an d ultra dma mode-6 interfaces and uses a standard ata driver that fits to all major operatin g systems such as microsofts windows series, apple s mac os family, and unix variants. featuring technologies as advanced wear-leveling al gorithms, s.m.a.r.t, built-in hardware ecc, enhanced data integrity, intelligent power failure recovery, secure protection zone and ata secure erase, apacers afd assures users of a versatile de vice on data storage. 1.1 performance-optimized controller the heart of an ata-flash drive is the ata controll er, which translates standard ata signals into the flash media data and controls of the flash media. t his proprietary ata controller is specifically desi gned to attain high data throughput from the host to the flash. 1.1.1 power management unit (pmu) the power management unit (pmu) controls the power consumption of the ata-flash drive. it reduces the power consumption of the ata-flash drive contro ller by putting circuitry not in operation into sle ep mode. the pmu has zero wake-up latency. 1.1.2 sram buffer the ata flash drive controller performs as an sram buffer to optimize the hosts data transfer to and from the flash media.

ata flash drive ap-fd18a20cxxxxxs-xxx 7 ? 2011 apacer technology inc. rev. 1.0 5. flash management 5.1 intelligent endurance design 5.1.1 advanced wear-leveling algorithms the nand flash devices are limited by a certain num ber of write cycles. when using a file system, frequent file table updates is mandatory. if some a rea on the flash wears out faster than others, it w ould significantly reduce the lifetime of the whole devi ce, 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. the scheme is achieved both via buffer management and apacer- specific advanced wear leveling to ensure that the lifetime of the flash media can be increased, and t he disk access performance is optimized as well. 5.1.2 s.m.a.r.t. technology s.m.a.r.t. is an acronym for self-monitoring, analy sis and reporting technology, an open standard allowing disk drives to automatically monitor their own health and report potential problems. it prote cts the user from unscheduled downtime by monitoring and st oring critical drive performance and calibration parameters. ideally, this should allow taking proac tive actions to prevent impending drive failure. ap acer smart feature adopts the standard smart command b0h to read data from the drive. when the apacer smart utility running on the host, it analyzes and reports the disk status to the host before the devi ce is in critical condition. 5.1.3 built-in hardware ecc the ata-flash drive uses bch error detection code ( edc) and error correction code (ecc) algorithms which correct up to twelve random single-bit errors for each 512-byte block of data. high performance is fulfilled through hardware-based error detection an d correction. 5.1.4 enhanced data integrity the properties of nand flash memory make it ideal f or applications that require high integrity while operating in challenging environments. the integrit y of data to nand flash memory is generally maintained through ecc algorithms and bad block man agement. flash controllers can support up to 8 bits ecc capability for accuracy of data transactio ns, and bad block management is a preventive mechanism from loss of data by retiring unusable me dia blocks and relocating the data to the other blo cks, along with the integration of advanced wear levelin g algorithms, so that the lifespan of device can be expanded.
ata flash drive ap-fd18a20cxxxxxs-xxx 8 ? 2011 apacer technology inc. rev. 1.0 5.2 intelligent power failure recovery 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 crash and ensures data integrity during an unexpected blackout. once power was failure before cached data writing back into flash, data in the cache will lost. the next time the power is on, the controller will check these fragmented data segmen t, and, if necessary, replace them with old data kept in flash until programmed successfully. 5.3 enhanced security level 5.3.1 secure protection zone partitioning with static commands to logically secu re data, protection zones are the solid frameworks of file vaults. 3 different types of zones, unprotecte d, read-only, and restricted, are offered for effor tless administration. when the product is shipped out of apacer, all sectors are in the unprotected zone, wh ich means there is no control on any data transaction. for further management control, the read-only zone can be set to be accessed exclusively for grantees, and the restricted zone, to be as the maximum security stockade with full administration privileg e required. a maximum of 4 zones can be configured as either restricted or read-only zone presenting conc urrently. the space outside these 4 zones is automatically in the unprotected zone if available. after the zone has been configured, the protection zone can be de-activated or re-activated by either softw are methods or hardware components. protection zone configuration is non-volatile and it will be in eff ect until the next set of configuration overwrites it. 5.3.2 ata secure erase accomplished by the secure erase (se) command, whic h added to the open ansi standards that control disk drives, ata secure erase is built into the d isk drive itself and thus far less susceptible to m alicious software attacks than external software utilities. it is a positive easy-to-use data destroy command, amounting to electronic data shredding. executing t he command causes a drive to internally completely erase all possible user data. this command is carri ed out within disk drives, so no additional softwar e 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 w hen power is back on.
