sata-disk module 4 apsdmxxxxg5an-pxxx 8 ? 2013 apacer technology inc. rev. 1.3 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 guarante e total reliability of nand flash memory array. whe n 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 current ly known technology that produce flash chips free o f bad blocks. in addition, bad blocks may develop during program/erase cycles. when host performs program/erase command on a block, bad block may app ear in status register. since bad blocks are inevitable, the solution is to keep them in control . apacer flash devices are programmed with ecc, blo ck mapping technique and s.m.a.r.t to reduce invalidit y 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 bl ocks cannot be overwritten and each p/e cycle wears down the lifespan of blocks gradually. repeatedly p rogram/erase cycles performed on the same memory cells will eventually cause some blocks to age fast er than others. this would bring flash storages to their end of service term sooner. wear leveling is an imp ortant mechanism that level out the wearing of bloc ks so that the wearing-down of blocks can be almost ev enly distributed. this will increase the lifespan o f 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 in to the ssd. in this urgent situation, the controlle r would run multiple write-to-flash cycles to store t he metadata for later block rebuilding. this urgent operation requires about several milliseconds to ge t it done. at the next power up, the firmware will perform a status tracking to retrieve the mapping t able and resume previously programmed nand blocks to check if there is any incompleteness of transmis sion. 5.5 ata secure erase aata secure erase is an ata disk purging command cu rrently embedded in most of the storage drives. defined in ata specifications, (ata) secure erase i s part of security feature set that allows storage drives to erase all user data areas. the erase proc ess usually runs on the firmware level as most of t he 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 pr otects it from malicious attack.
sata-disk module 4 apsdmxxxxg5an-pxxx 9 ? 2013 apacer technology inc. rev. 1.3 5.6 s.m.a.r.t. s.m.a.r.t. is an abbreviation for self-monitoring, analysis and reporting technology, a self-monitorin g system that provides indicators of drive health as well as potential disk problems. it serves as a war ning for users from unscheduled downtime by monitoring a nd displaying critical drive information. ideally, this should allow taking proactive actions to prevent dr ive failure and make use of s.m.a.r.t. information for future product development reference. apacer devices use the standard smart command b0h t o 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 bl ock 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 repor ts the disk status to the host before the device reach es in critical condition. note: attribute ids may vary from product models du e to various solution design and supporting capabilities. 5.7 trim trim, though in capital letters usually, is a memor y 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 longe r valid, due to erases by the host or operating sys tem, such as file deletions or disk formatting. once not ified, ssd will begin the discard of the invalid lb as and retain more space for itself, in fact, the discarde d 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 bloc ks in garbage collected sectors. noticeably, a file de letion command by host or operating system never actually erases the actual content, rather, just th e file is marked as deleted. this issue is even spe cifically 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 .
