ata flash drive 185 ap-fd18b20bxxxxxs-xx 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. 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 configurable 18, 16, 15, 14, 8, 7, 6 bits of random errors for each 512-byte block of data. high performance is fulfilled through hardwar e-based error detection and 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 185 ap-fd18b20bxxxxxs-xx 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 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.
