zeus 2.5-inch ata solid state drive 9 p roduct d escription general description the zeus 2.5-inch ata solid state drive (ssd) is a non-volatile, mass storage device. the drive is intended as a replacement for a standard ide/ata- compliant hard disk drive (hdd). no additional device drivers are required, and the drive can be configured as a boot or data storage device. ata interface the ssd can be installed in any operating system environment that supports ata-6 or greater devices. the drive is configured wi th a standard 44-pin ide/ata interface, is fully ata-6 compliant, and conforms to the same mechanical and mounting requirements as standard rotating disk drives. the drive supports primary/secondary (device 0/devi ce 1) mode operation via a set of jumper pins. drive capacities the ssd is available in unformatted memory capac ities of 8, 16, 32 and 64 gigabytes. the memory consists of single-level ce ll (slc) nand flash components. performance zeus ssds can operate at sustained data transfer rates of up to 40 mb per second. power consumption is kept to a minimum; the ssds can be powered from a single 5-volt source. the solid state design eliminates electrom echanical noise and delay inherent in traditional magnetic rotating media. the wear-leveling and b ad-block mapping algorit hms ensure consistency, accuracy, and integrity of user data. data reliability is achieved through embedded error detection and error correction code (edc/ecc). data security zeus ssds offer optional user-defined data saniti zation (purge) features. supporting both sanitized erase/fill and non-recoverable saniti zation options, the ssds can be configured to remove data from the drive, freeing storage space for later reuse, or to remove data and destroy the storage media, making the ssd unusable and data retrieval impossible. the data security features of the drives comply with department of defense (dod) and us military data security standards, including afssi 5020, ar 380-19, navso p-5239-26, nispom dod 5220.22-m and nsa 130-2.
10 zeus 2.5-inch ata solid state drive p erformance c haracteristics ata (ide) bus modes zeus ssds support the foll owing ata operating modes: ? pio modes 0 - 4 ? dma modes 0 - 2 ? ultra dma modes 0 - 5 endurance the useful life of flash media is limited by the number of write/er ase operations that can be performed on the media. to extend the useful life of the ssd, special wear-leveling and bad-block mapping algorithms are integrat ed in the firmware. wear-leveling the dynamic wear-leveling algorithm integrated in the firmware guarantees that erase/write cycles are evenly distributed across all of the flash memo ry block locations. wear -leveling eliminates repeated writes to the same physical flash memo ry location, thereby pr eventing blocks from premature wear. bad-block management the bad-block mapping algorithm r eplaces bad blocks with new ones from available spares. two percent (2%) of the flash memory is held in re serve (spare block) for bad block replacement. bad blocks in the media are flagged when detected. t he next time an attempt is made to access a flagged block, it is immediately replaced by a spare block. the bad block mappi ng function enables data to be automatically transferred from a bad sector to an avai lable spare block. notes : 1 stec inc. scans for bad blocks during the manuf acturing process at the initial installation of the flash components. bad blocks are mapped and identified durin g the manufacturing process. 2 the maximum amount of available user space will not be less than 97% of the total flash capacity, i.e., the reserved space will not exceed more than 3% of the total drive volume data retention data stored on a zeus ssd will remain valid for t en (10) years without r equiring power support. the unit can be stored under certain environmental conditions for extended periods without any occurrence of data degradation.
zeus 2.5-inch ata solid state drive 11 error detection and correction the error detection code and error correcting code (edc/ecc) helps maintain data integrity by allowing single or multiple bit corrections to the dat a stored in the flash array. if the data in the flash array is corrupted due to aging or during the pr ogramming process, the edc/ecc will compensate for the errors to ensure the delivery of accurate data to the host computer. the edc/ecc engine is capable of correcting up to 4 bytes in error and detec ting up to 5 bytes in error. an extensive retry algorithm is also implemented on all zeus ssds, so that single ev ent disturbances such as esd or emf occurring during a read operat ion can be readily overcome. reliability ? dc power is maintained as specified in the datasheet ? errors caused by the host are excluded from rates ? errors from the same causes are counted as 1 block ? data stream is assumed random error rates table 1 lists the error limit specificat ions. when all data correction me chanisms are enabled, the error rate will be sustained through all oper ating temperature ranges as specif ied in the previous sections. table 1. error limits built-in self test (bist) during power-up, the micro-contro ller tests the controller me mory, and then performs a back-end status check to verify proper flash memory contro ller operations. if a fault condition is detected in the flash memory controller, the ssd?s status is reported as failed. mount time the amount of time required to initialize and mount a zeus ssd varies according to the operating system (windows ? , linux ? , etc.) in which the ssd is running and the storage capacity of the drive. seek time unlike a magnetic rotating disk, the ssd has no read/ write heads or platters. there is no seek time or rotational latency issues. the ssds dramatic ally improve transaction throughput, particularly for applications that are configured to take adv antage of the characteristics of the drive. error type maximum number of errors recoverable data error 1 bit in 10 20 unrecoverable data error less than 1 bit in 10 20
12 zeus 2.5-inch ata solid state drive data transfer rates the data transfer rate varies according to the flash controller/flash memory conf iguration of the drive. the scalable architecture of the drive is capabl e of accommodating sustained and burst data transfer rates as listed in table 2 . table 2. data transfer rates purge times the time required to purge a zeus ssd depends on t he actual purge option invoked by the user and the flash controller/flash memory configuration of the drive. a list of repr esentative purge times is listed in table 3 , with the value expressed in seconds per 32 gigabytes (sec/32gb) for each purge option. table 3. purge times repairs a defective ssd should be replaced. there are no parts, assemblies or subassemblies that can be repaired individually by the user. please see the section titled certification and warranty on the inside of the back cover page. unauthorized repairs to the ssd will void the warranty. preventative maintenance no preventative maintenance is required. the ssd unit is sealed at the factory, and there are no parts, assemblies, or subassemblies that requi re preventative maintenance on behalf of the user. please see the section titled certification and warranty on the inside of the back cover page. unauthorized maintenance to the ssd will void the warranty. parameter value units average access 0.3 m/sec average latency 0.3 m/sec sustained read 40 megabytes/sec sustained write 26 megabytes/sec burst read 66 megabytes/sec burst write 66 megabytes/sec purge option value units basicpurge 360 sec/32gb rapidpurge 9 sec/32gb milpurge 1,200 sec/32gb intelligent destructive purge 2 sec/32gb

zeus 2.5-inch ata solid state drive 15 power savings commands zeus ssds support the following power savings co mmands and respond with the appropriate status: ? check power mode ? idle ? standby ? standby immediate ? sleep the drives comply with all specifications that def ine the behavior of storage devices as it relates to power management and advanced power management (apm). when the ssds receive a power management command, all data in the write cache bu ffer is written to the media before drive ready is asserted. power mode at power on the drives comply with the ata-6 power managem ent specification. during the power on reset sequence, the drive functions pr operly and responds as appropriate. in addition, if a srst (ata interface reset) occurs during this sequence, the dr ives still respond normally. after power on or hard reset, the drive goes into idle or stand by mode, depending on the setting by the host. grounding signal and chassis grounds are connect ed together in the drive. to ensure minimal em emissions, the user should provide maximum surface contac t area when connecting the drive to the chassis ground.
16 zeus 2.5-inch ata solid state drive i nterface s pecifications ssd operation the zeus ssd comprises three primary functional blocks: the ata (ide) interface connector, zeus ssd controller and nand flash memory. a de scription of each drive component appears under functional blocks . read/write data transfer requests are initiated by the host via the ata (ide) bus interface. once received, the zeus controller, under the directi on of the microcontroller, processes the request. commands that do not require data to be read from or written to the flash memory controller are typically handled by the zeus controller. some co mmands may require the zeus controller to use external circuitry (for example, intelligent destructive purge?), that do not involve the flash memory controller. when a write operation is requested and data is re ceived, the controller uses integrated dma controllers to transfer the data from host memory to the flash memory controller. through a standard ata (ide) interface, the flash memory controller transfers the data from the zeus controller to available locations in the local flash memory of the ssd. zeus ssd storage capacity can range between from 8gb to 64gb, with internal ide transfe r rates of 26 mb per second. the zeus controller notifies the host after the write operation is completed. if a read request is received, the zeus controller re trieves the data from the local flash memory via the flash memory controller. if the zeus controlle r is responding to a pio read operation, it presents the data to the ata bus. if it is responding to a ud ma read request, the zeus controller writes the data directly to system memory on the host. regardles s of the type of operation (pio or udma), the zeus controller notifies the host wh en the data is ready for transmission. the microcontroller is responsible for initiating and controlling all activity within the zeus contro ller, including bad-block mapping and executing the wear-leveling algorithms. the zeus controller decodes an incoming host command, and configures the appropriate inte rrupts and status for the local microprocessor to handle various ata commands. for read and write transfer commands, the hardware can handle the initial handshake with the host automati cally. if firmware enables full auto mode, read and write transfers can be fully handled by hardware with minimum firmware support.
zeus 2.5-inch ata solid state drive 17 primary and secondary modes the zeus ssd is configured as a high-performance i/o device and supports primary (device 0) and secondary (device 1) modes: i/o primary and secondary ata (ide) modes primary and secondary drive addressing modes allow hosts to use the ata-standard?s reserved disk drive i/o addresses. this provi des system designers with the simplest way to accommodate ata- protocol devices. addressing modes zeus ssds, on a command-by-command basis, c an operate in either chs or lba addressing modes. identify drive information (see identify drive information on page 26.) signals the host whether the drive supports lba mode. the host selects lba mode via the drive/head register. sector number, cylinder low, cyli nder high, and drive/head register bits hs3=0 contain the zero- based lba. the sectors are linear ly mapped with: lba = 0 => cylinder 0, head 0, sector 1. regardless of the translation mode, a sector lba address does not change. lba = (cylinder * no of heads + head) * (sectors/track) + (sector - 1). table 6 lists the supported ide addressing modes. table 6. ata (ide) bus addressing modes device mode description primary drive address at system ata i/o address 1f0h - 1f7h and 3f6h - 3f7h. the host must provide chip-enable #cs0 and #cs1. the ssd decodes addresses da0 - da2. secondary drive address at system ata i/o address 170h - 177h and 376h - 377h. the host must provide chip-enable #cs0 and #cs1. the ssd decodes addresses da0 - da2. #cs0 #cs1 da2 da1 da0 #iord - ?0? #iowr - ?0? 1 1 x x x hi-z not used 1 0 0 x x hi-z not used 1 0 1 0 x hi-z not used 0 0 x x x invalid invalid 1 0 1 1 0 alternate status device control 1 0 1 1 1 device address not used 0 1 0 0 0 data data 0 1 0 0 1 error feature 0 1 0 1 0 sector count sector count 0 1 0 1 1 sector number sector number 0 1 1 0 0 cylinder low cylinder low 0 1 1 0 1 cylinder high cylinder high 0 1 1 1 0 drive/head drive/head 0 1 1 1 1 status command

zeus 2.5-inch ata solid state drive 63 a cronyms and a bbreviations a arm (advanced risc machine) (arm, originally acorn risc machine). a series of low- cost, power-efficient 32-bit risc microprocessors for embedded control, computing, digital signal processing, games, consumer multimedia and portable applications. ata (at attachment) the ide interface is officially known as the ata specification. ata-2 (fast ata) defined the faster transfer rates used in enhanced ide (eide). ata-3 added interface improvements, including the ability to report potential problems (see s.m.a.r.t.). starting with ata-4, either the word ?ultra? or the transfer rate was added to the name in various combinations. for example, at 33 mbytes/ sec, terms such as ultra ata and ata-33 have been used. in addition, ultra ata-33, dma-33 and ultra dma-33 are also found. c cfa (computer fraud and abuse act of 1986) the cfa was a significant step forward in the prosecution of unauthorized access to computer systems and networks. the act applies to ?federal interest computers? which include systems used by the u.s. government, as well as most financial institutions. the act makes unauthorized penetration or other damage to such systems a felony. chs cylinder, head, sector a disc-drive system and method for generating logical zones that each have an approximate number of spare sectors, and that are used to translate logical block addresses. cisc (complex instruction set computer) pronounced ?sisk.? the traditional architecture of a computer which uses microcode to execute very comprehensive instructions. instructions may be variable in length and use all addressing modes, requiring complex circuitry to decode them. d dma (direct memory access ) specialized circuitry or a dedicated microprocessor that transfers data from memory to memory without using the cpu. although dma may periodically steal cycles from the cpu, data are transferred much faster than using the cpu for every byte of transfer. dod (department of defense) the military branch of the u.s. government, which is under the direction of the secretary of defense, the primary defense policy adviser to the president. dsl (digital subscriber line) a technology that dramatically increases the digital capacity of ordinary telephone lines (the local loops) into the home or office. dsl speeds are tied to the distance between the customer and the telco central office (co). dsl is geared to two types of usage. asymmetric dsl (adsl) is for internet access, where fast downstream is required, but slow upstream is acceptable. symmetric dsl (sdsl, hdsl, etc.) is designed for short haul connections that require high speed in both directions. dslam (dsl access multiplexer) a central office (co) device for adsl service that combines voice traffic and dsl traffic onto a customer's dsl line. it also separates incoming phone and data signals and directs them onto the appropriate carriers network. e edc/ecc (error detection c ode/error correction code) a memory system that tests for and corrects errors automatically, very often without the operating system being aware of it. when writing the data into memory, ecc circuitry generates checksums from the binary sequences in the bytes and stores them in an additional seven bits of memory for 32-bit data paths or eight bits for 64-bit paths. when data are retrieved from memory, the checksum is recomputed to determine if any data bits have been corrupted. such systems can typically detect and automatically correct errors of one bit per word and can detect, but not correct, errors greater than one bit.
64 zeus 2.5-inch ata solid state drive f fpga (field programmable gate array) a type of gate array that is programmed in the field rather than in a semiconductor fabrication facility. containing up to hundreds of thousands of gates, there are a variety of fpga architectures on the market. some are very sophisticated, including not only programmable logic blocks, but programmable interconnects and switches between the blocks. the interconnects take up a lot of fpga real estate, resulting in a chip with very low gate density compared to other technologies. h hdd (hard disk drive) the primary computer storage medium, made of one or more aluminum or glass platters, coated with a ferromagnetic material. most hard disks are ?fixed disks,? which have platters that reside permanently in the drive. i i/o (input/output) transferring data between the cpu and a peripheral device. every transfer is an output from one device and an input into another. ide (integrated drive electronics) a type of hardware interface widely used to connect hard disks, cd-roms and tape drives to a pc. ide was always the more economical interface, compared to scsi. starting out with 40mb capacities years ago, 20gb ide hard disks have become entry level, costing a fraction of a cent per megabyte. io (input/output; see i/o) l lba (logical block addressing) a method used to support ide hard disks larger than 504mb (528,482,304 bytes) on pcs. lba provides the necessary address conversion in the bios to support drives up to 8gb. bios after mid-1994, which are sometimes called ?enhanced bios,? generally provide lba conversion. lba support is required for compatibility with the fat32 directory. lsb (least significant byte) ?byte? defines a sequence of 8-bits, with the right-most bit being the least significant and the left-most bit being the most- significant. lsw (least significant word) ?word? denotes sequence of 4 bytes, or 32 bits, with the left-most being the least significant, and the right-most being the most significant. ?double-word? denotes sequence of two words, or 64bits, with the left most word being the least significant, and the right-most - the most significant. note, that the definition of ?word? defines a little-endian scheme, so for big- endian platforms, or network applications, special steps need to be taken to reorder the bytes form the input stream. m mlc (multi-level cell) a flash memory technology that stores more than one bit of data per cell. traditional flash memory defines a 0 or 1 bit, based on a single voltage threshold. the patterns of two bits (0-0, 0-1, 1-0, and 1-1) can be achieved with four voltage levels and eight levels of voltage can yield all the combinations in three bits. msb (most significant) ?byte? defines a sequence of 8-bits, with the right-most bit being the least significant and the left-most bit being the most- significant. msw (most significant word) ?word? denotes sequence of 4 bytes, or 32 bits, with the left-most being the least significant, and the right-most being the most significant. ?double-word? denotes sequence of two words, or 64bits, with the left most word being the least significant, and the right-most - the most significant. note, that the definition of ?word? defines a little-endian scheme, so for big- endian platforms, or network applications, special steps need to be taken to reorder the bytes form the input stream. n nand (not and) a boolean logic operation that is true if any single input is false. two-input nand gates are often used as the sole logic element on gate array chips, because all boolean operations can be created from nand gates. p pio (programmed input/output) the data transfer mode used by ide drives. pio modes use the registers of the cpu for data transfer in contrast with dma, which transfers directly between main memory and the peripheral device.
zeus 2.5-inch ata solid state drive 65 r risc (reduced instruction set computer) a computer architecture that reduces chip complexity by using simpler instructions. risc compilers have to generate software routines to perform complex instructions that were previously done in hardware by cisc computers. in risc, the microcode layer and associated overhead is eliminated. s slc single-level cell a flash memory technology that stores one bit of data per memory cell; supporting only two states: erased (1) or programmed (0). smart (self-monitoring analysis and reporting technology) an ?early warning system? for anticipating pending drive problems. the drive?s integrated controller works with various sensors to monitor several aspects of the drive's performance. using this status information, smart determines if the drive is behaving normally or not, and then makes the information available to software that probes the drive. ssd (solid state disk) disk drive that uses memory chips instead of rotating platters for data storage. used in battery-powered handheld devices as well as desktop computers and servers, solid state disks (ssds) are faster than regular disks because there is zero latency (there is no read/write head to move). they are also more rugged than hard disks and offer greater protection in hostile environments. t true-ide flash memory devices (such as cf cards) have a pin that when connected to the proper voltage at power-up selects the ?true-ide? mode of operation instead of the ?pc-card-ata? mode of operation. this is the mode used in the interface. u ultra ata an enhanced version of the ide interface that transfers data at 33, 66 or 100 mbytes/sec. these enhancements are also called ?ultra dma,? ?udma,? ?ata-33,? ?ata-66,? ?ata-100,? ?dma-33,? ?dma-66? and ?dma-100.? ultra dma (see ultra ata)
