Flash CF is a flash memorymass storage device used mainly in portable electronic devices. The format was specified and the devices were first manufactured by San. Disk in 1. 99. 4. Compact. Flash became the most successful of the early memory card formats, surpassing Miniature Card and Smart. Media. Subsequent formats, such as MMCSD, various Memory Stick formats, and x. D Picture Card offered stiff competition. Most of these cards are smaller than Compact. Flash while offering comparable capacity and speed. Proprietary memory card formats for use in professional audio and video, such as P2 and Sx. S, are faster, but physically larger and more costly. Compact. Flash remains popular and is supported by many professional devices and high end consumer devices. As of 2. 01. 7, both Canon56 and Nikon7 use Compact. Flash for their flagship digital still cameras. Canon also chose Compact. Flash as the recording medium for its professional high definition tapeless video cameras. Ikegami professional video cameras can record digital video onto Compact. Flash cards through an adaptor. Traditional Compact. Flash cards use the Parallel ATA interface, but in 2. Compact. Flash, CFast was announced. CFast also known as Compact. Fast is based on the Serial ATA interface. In November 2. 01. San. Disk, Sony and Nikon presented a next generation card format to the Compact. Flash Association. The new format has a similar form factor to CFCFast but is based on the PCI Express interface instead of Parallel ATA or Serial ATA. With potential read and write speeds of 1 Gbits 1. MBytes and storage capabilities beyond 2 Ti. B, the new format is aimed at high definition camcorders and high resolution digital cameras, but the new cards are not backward compatible with either Compact. Flash or CFast. The XQD card format was officially announced by the Compact. Flash Association in December 2. Descriptionedit. A 1. GB Compact. Flash card installed in a 2. IDE port with adapter. There are two main subdivisions of CF cards, 3. I and 5 mm thick type II CF2. The type II slot is used by miniature hard drives and some other devices, such as the Hasselblad CFV Digital Back for the Hasselblad series of medium format cameras. There are four main card speeds original CF, CF High Speed using CFCF2. CF 3. 0 standard and the faster CF 4. Compact. Flash was originally built around Intels NOR based flash memory, but has switched to NAND technology. CF is among the oldest and most successful formats, and has held a niche in the professional camera market especially well. It has benefited from both a better cost to memory size ratio and, for much of the formats life, generally greater available capacity than other formats. CF cards can be used directly in a PC Card slot with a plug adapter, used as an ATA IDE or PCMCIA storage device with a passive adapter or with a reader, or attached to other types of ports such as USB or Fire. Wire. As some newer card types are smaller, they can be used directly in a CF card slot with an adapter. Formats that can be used this way include SDMMC, Memory Stick Duo, x. D Picture Card in a Type I slot and Smart. Media in a Type II slot, as of 2. Some multi card readers use CF for IO as well. Technical detailseditThe Compact. Flash interface is a 5. PCMCIA1. 4 connector. It can be easily slipped into a passive 6. PCMCIA Type II to CF Type I adapter that fully meets PCMCIA electrical and mechanical interface specifications, according to compactflash. The interface operates, depending on the state of a mode pin on power up, as either a 1. PC Card 0x. 7FF address limit or as an IDE PATA interface. Unlike the PC Card interface, no dedicated programming voltages Vpp. Vpp. 2 are provided on the Compact. Flash interface. 1. Compact. Flash IDE mode defines an interface that is smaller than, but electrically identical to, the ATA interface. The CF device contains an ATA controller and appears to the host device as if it were a hard disk. CF devices operate at 3. Compact. Flash supports C H S and 2. CF 5. 0 introduced support for LBA 4. CF cards with flash memory are able to cope with extremely rapid changes in temperature. Industrial versions of flash memory cards can operate at a range of 4. C. NOR based flash has lower density than newer NAND based systems, and Compact. Flash is therefore the physically largest of the three memory card formats introduced in the early 1. JEIDAPCMCIA Memory Card formats. The other two are Miniature Card Mini. Microsoft Access 2010 Vba Insert Into Table As Select. Card and Smart. Media SSFDC. However, CF did switch to NAND type memory later. The IBMMicrodrive format, later made by Hitachi, implements the CF Type II interface, but is a hard disk drive HDD as opposed to solid state memory. Seagate also made CF HDDs. Compact. Flash IDE ATA emulation speed is usually specified in x ratings, e. This is the same system used for CD ROMs and indicates the maximum transfer rate in the form of a multiplier based on the original audio CD data transfer rate, which is 1. Bytes. RK1. 50 k. Bytesdisplaystyle RKcdot 1. Byteswhere R transfer rate, K speed rating. For example, 1. 33x rating means transfer speed of 1. Bytes 1. 9,9. 50 k. Bytes 2. 0 MBs. These are manufacturer speed ratings. Actual transfer speed may be higher, or lower, than shown on the card1. The speed rating quoted is almost always the read speed, while write speed is often slower. Solid stateeditFor reads, the onboard controller first powers up the memory chips from standby. Reads are usually in parallel, error correction is done on the data, then transferred through the interface 1. Error checking is required due to soft read errors. Writes require powerup from standby, wear leveling calculation, a block erase of the area to be written to, ECC calculation, write itself an individual memory cell read takes around 1. Because the USB 2. MBytes and lacks bus mastering hardware, USB 2. Modern UDMA 7 Compact. Flash Cards provide data rates up to 1. Mbytessec1. 9 and require USB 3. A direct motherboard connection is often limited to 3. MBytes because IDE to CF adapters lack high speed ATA 6. MBytes plus cable support. Power on from sleepoff takes longer than power up from standby. Magnetic mediaeditMany 1 inch 2. Microdrive typically spin at 3. RPM, so rotational latency is a consideration, as is spin up from standby or idle. Seagates 8 GB ST6. CF drive2. 1 spins up fully within a few revolutions but current drawn can reach up to 3. A mean current. Its average seek time is 8 ms and can sustain 9 MBytes read and write, and has an interface speed of 3. MBytes. Hitachis 4 GB Microdrive is 1. MBytes. Capacities and compatibilityeditThe CF 5. Specification supports capacities up to 1. PB using 4. 8 bit logical block addressing LBA. Prior to 2. 00. 6, CF drives using magnetic media offered the highest capacities up to 8 GB. Now there are solid state cards with higher capacities up to 5. GB. 2. 3As of 2. SSDs have supplanted both kinds of CF drive for large capacity requirements. Solid state capacitieseditSan. Disk announced its 1. GB Extreme III card at the photokina trade fair, in September, 2. That same month, Samsung announced 1. GB CF cards. 2. 5 Two years later, in September, 2. PRETEC announced 1. GB cards. 2. 6Magnetic media capacitieseditSeagate announced a 5 GB 1 inch hard drive in June, 2. GB version in June, 2. Use in place of a hard disk driveedit.
