102-546: A Date First Available since 4 August 2009. The original xD cards (Type S) were available in 16 MB to 512 MB capacities. The Type M card, released in February 2005, uses multi-level cell (MLC) architecture to achieve a theoretical storage capacity of up to 8 GB. As of June 2010 , Type M cards are available in sizes from 256 MB to 2 GB. However, the Type M suffers from slower read/write speeds than
153-455: A RAID configuration. CF cards may perform the function of the master or slave drive on the IDE bus, but have issues sharing the bus. Moreover, late-model cards that provide DMA (using UDMA or MWDMA) may present problems when used through a passive adapter that does not support DMA. Original PC Card memory cards used an internal battery to maintain data when power was removed. The rated life of

In both cases, the computer sees the card as a mass storage device containing image files, although software or firmware can alter this representation. Card readers may be integrated into the PC or attached by cable. Adapters are available to allow an xD picture card to be plugged into other readers (and in some cases cameras), including PC card , parallel port , CompactFlash and SmartMedia . A chart showing which sizes and types of xD cards were available can be found below.

306-557: A 5 GB "1-inch hard drive" in June, 2004, and an 8 GB version in June, 2005. In early 2008, the CFA demonstrated CompactFlash cards with a built in SATA interface. Several companies make adapters that allow CF cards to be connected to PCI , PCMCIA , IDE and SATA connections, allowing a CF card to act as a solid-state drive with virtually any operating system or BIOS, and even in
357-458: A CF card slot with an adapter. Formats that can be used this way include SD / MMC , Memory Stick Duo, xD-Picture Card in a Type I slot and SmartMedia in a Type II slot, as of 2005. Some multi-card readers use CF for I/O as well. The first CompactFlash cards had capacities of 2 to 10 megabytes. This increased to 64 MB in 1996, 128 MB in 1998, 256 MB in 1999, 512 MB in 2001, and 1 GB in 2002. The CompactFlash interface
408-519: A FAT32 format. The way many digital cameras update the file system as they write to the card creates a FAT32 bottleneck. Writing to a FAT32-formatted card generally takes a little longer than writing to a FAT16-formatted card with similar performance capabilities. For instance, the Canon EOS 10D writes the same photo to a FAT16-formatted 2 GB CompactFlash card somewhat faster than to a same speed 4 GB FAT32-formatted CompactFlash card, although
459-524: A block erase of the area to be written to, ECC calculation, write itself (an individual memory cell read takes around 100 ns, a write to the chip takes 1ms+ or 10,000 times longer). Because the USB 2.0 interface is limited to 35 MB/s and lacks bus mastering hardware, USB 2.0 implementation results in slower access. Modern UDMA-7 CompactFlash Cards provide data rates up to 145 MB/s and require USB 3.0 data transfer rates. A direct motherboard connection
510-540: A boot image written on it. Additionally, SmartMedia and xD card readers can be used to read the data from NAND flash chips in electronic devices, by soldering leads between the chip and the card reader. Some Olympus cameras offer camera-based panoramic processing. In those cameras that support both xD and CompactFlash cards, panoramic processing only works with images stored on the xD card, if installed. Newer Olympus cameras have neither xD cards nor this restriction. Unsubtantiated reports claim that some cameras such as
561-452: A few revolutions but current drawn can reach up to 350 milliamps and runs at 40-50 mA mean current. Its average seek time is 8 ms and can sustain 9 MB/s read and write, and has an interface speed of 33 MB/s. Hitachi's 4 GB Microdrive is 12 ms seek, sustained 6 MB/s. The CF 5.0 Specification supports capacities up to 128 PiB using 48-bit logical block addressing (LBA). Prior to 2006, CF drives using magnetic media offered
SECTION 10
#1732764949077612-576: A growing number of cameras, video recorders, and audio recorders that use the faster data rates offered by CFast media. As of 2017, in the wider embedded electronics industry, transition from CF to CFast is still relatively slow, probably due to hardware cost considerations and some inertia (familiarity with CF) and because a significant part of the industry is satisfied with the lower performance provided by CF cards, thus having no reason to change. A strong incentive to change to CFast for embedded electronics companies using designs based on Intel PC architecture
663-503: 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 format's 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 FireWire . As some newer card types are smaller, they can be used directly in
714-549: A range of −45 °C to +85 °C. NOR -based flash has lower density than newer NAND -based systems, and CompactFlash is therefore the physically largest of the three memory card formats introduced in the early 1990s, being derived from the JEIDA/PCMCIA Memory Card formats. The other two are Miniature Card (MiniCard) and SmartMedia (SSFDC). However, CF did switch to NAND type memory later. The IBM Microdrive format, later made by Hitachi , implements
765-530: Is a 50-pin subset of the 68-pin PCMCIA connector. "It can be easily slipped into a passive 68-pin PCMCIA Type II to CF Type I adapter that fully meets PCMCIA electrical and mechanical interface specifications", according to compactflash.org. The interface operates, depending on the state of a mode pin on power-up, as either a 16-bit PC Card (0x7FF address limit) or as an IDE (PATA) interface. Unlike
816-613: Is based on the Serial ATA (SATA) interface, rather than the Parallel ATA /IDE (PATA) bus for which all previous versions of CompactFlash are designed. CFast is also known as CompactFast. CFast 1.0/1.1 supports a higher maximum transfer rate than current CompactFlash cards, using SATA 2.0 (300 MB/s) interface, while PATA is limited to 167 MB/s using UDMA 7 . CFast cards are not physically or electrically compatible with CompactFlash cards. However, since SATA can emulate
867-535: Is based on the Serial ATA interface. In November 2010, SanDisk, Sony and Nikon presented a next generation card format to the CompactFlash Association. The new format has a similar form factor to CF/CFast but is based on the PCI Express interface instead of Parallel ATA or Serial ATA. With potential read and write speeds of 1 Gbit/s (125 MB/s ) and storage capabilities beyond 2 TiB ,
918-462: Is declining as CFexpress is taking over. As of 2022, both Canon and Nikon's newest high end cameras, e.g. the Canon EOS R5 , Canon EOS R3 , and Nikon Z 9 use CFexpress cards for the higher performance required to record 8K video. Traditional CompactFlash cards use the Parallel ATA interface, but in 2008, a variant of CompactFlash, CFast was announced. CFast (also known as CompactFast)
969-516: Is less reliable than magnetic media. Car PC Hacks suggests disabling the Windows swap file and using its Enhanced Write Filter (EWF) to eliminate unnecessary writes to flash memory. Additionally, when formatting a flash-memory drive, the Quick Format method should be used, to write as little as possible to the device. Most CompactFlash flash-memory devices limit wear on blocks by varying
1020-442: Is often limited to 33 MB/s because IDE to CF adapters lack high speed ATA (66 MB/s plus) cable support. Power on from sleep/off takes longer than power up from standby. Many 1-inch (25 mm) hard drives (often referred to by the trademarked name " Microdrive ") typically spin at 3600 RPM, so rotational latency is a consideration, as is spin-up from standby or idle. Seagate's 8 GB ST68022CF drive spins up fully within
1071-447: Is prone to frequent soft read errors. The CompactFlash card includes error checking and correction (ECC) that detects the error and re-reads the block. The process is transparent to the user, although it may slow data access. As a flash memory device is solid-state , it is less affected by shock than a spinning disk. The possibility for electrical damage from upside-down insertion is prevented by asymmetrical side slots, assuming that

#17327649490771122-729: The CF Type II interface, but is a hard disk drive (HDD) as opposed to solid-state memory. Seagate also made CF HDDs. CompactFlash IDE (ATA) emulation speed is usually specified in "x" ratings, e.g. 8x, 20x, 133x. 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 150 kB/s. where R = transfer rate, K = speed rating. For example, 133x rating means transfer rate of: 133 × 150 kB/s = 19,950 kB/s ≈ 20 MB/s. These are manufacturer speed ratings. Actual transfer rate may be higher, or lower, than shown on
1173-570: The E-3 and E-5 among others continue to use CompactFlash cards as well. Certain final Olympus cameras using xD cards are also supporting microSD cards with a special adapter. Fuji released its last digital camera accepting that card, namely Fujifilm FinePix F200EXR (a variant of 2008 FinePix F100fd), being released back in Q2 2009, as being moving away from xD format since Q4 2008. Amazon Best Sellers in xD-Picture Cards reports no products offered with
1224-536: The E-450 only support panoramic processing when using Olympus branded xD cards. The model numbers have not been documented. In this case, there appears to be a workaround: it appears that the card manufacturer information is simply stored in the flash memory, in the Card Information Structure. Thus, it is possible to alter another brand of xD card to present itself as Olympus xD card by accessing
1275-560: 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 CF+/CF2.0), faster CF 3.0 standard and the faster CF 4.0 standard adopted as of 2007. CompactFlash was originally built around Intel 's NOR -based flash memory, but has switched to NAND technology. CF is among the oldest and most successful formats, and has held
1326-547: The PATA command protocol, existing CompactFlash software drivers can be used, although writing new drivers to use AHCI instead of PATA emulation will almost always result in significant performance gains. CFast cards use a female 7-pin SATA data connector , and a female 17-pin power connector, so an adaptor is required to connect CFast cards in place of standard SATA hard drives which use male connectors. The first CFast cards reached
1377-845: The PC Card interface, no dedicated programming voltages (Vpp1 and Vpp2) are provided on the CompactFlash interface. CompactFlash 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 3.3 volts or 5 volts, and can be swapped from system to system. CompactFlash supports C-H-S and 28-bit logical block addressing (CF 5.0 introduced support for LBA-48). CF cards with flash memory are able to cope with extremely rapid changes in temperature. Industrial versions of flash memory cards can operate at
1428-496: The active pins of the two devices. xD cards share this characteristic with the older SmartMedia cards, which are also basically raw NAND flash chips, albeit in a larger package. xD and SmartMedia cards can be used by hobbyists as a convenient source of NAND flash memory chips for custom projects. For example, the Mattel Juice Box PMP can be booted into Linux using a modified cartridge containing an xD card with
1479-513: The battery was the only reliability issue. CompactFlash cards that use flash memory, like other flash-memory devices, are rated for a limited number of erase/write cycles for any "block." While NOR flash has higher endurance, ranging from 10,000 to 1,000,000, they have not been adapted for memory card usage. Most mass storage usage flash are NAND based. As of 2015 NAND flash were being scaled down to 16 nm. They are usually rated for 500 to 3,000 write/erase cycles per block before hard failure. This
1530-457: The card depending on several factors. The speed rating quoted is almost always the read speed, while write speed is often slower. For 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 16 bits at a time. Error checking is required due to soft read errors. Writes require powerup from standby, wear leveling calculation,
1581-404: The cards' storage architecture, newer Type M and H cards may have compatibility issues with some older cameras (especially video recording). Compatibility lists are available for Olympus: Olympus America's and Fujifilm's. Newer cards are incompatible with some card readers . Pictures may be transferred from a digital camera's xD card to a personal computer by plugging the camera into the PC by

1632-487: The devices be read by personal computers but also suits the limited processing ability of some consumer devices such as cameras . There are varying levels of compatibility among FAT32-compatible cameras, MP3 players, PDAs, and other devices. While any device that claims FAT32-capability should read and write to a FAT32-formatted card without problems, some devices are tripped up by cards larger than 2 GB that are completely unformatted, while others may take longer to apply
1683-443: The gaming industry (used in slot machines), as a natural evolution from the by then well-established CF cards. Current gaming industry supporters of the format include both specialist gaming companies (e.g. Aristocrat Leisure ) and OEMs such as Innocore (now part of Advantech Co., Ltd. ). The CFast 2.0 specification was released in the second quarter of 2012, updating the electrical interface to SATA 3.0 (600 MB/s). As of 2014,
1734-561: The highest capacities (up to 8 GiB ). Now there are solid-state cards with higher capacities (up to 512 GB). As of 2011, solid-state drives (SSDs) have supplanted both kinds of CF drive for large capacity requirements. SanDisk announced its 16 GB Extreme III card at the photokina trade fair, in September, 2006. That same month, Samsung announced 16, 32 and 64 GB CF cards. Two years later, in September, 2008, PRETEC announced 100 GB cards. Seagate announced
1785-501: The host device can read them. CompactFlash cards are often used instead of hard drives in embedded systems, dumb terminals and various small form-factor PCs that are built for low noise output or power consumption. CompactFlash cards are often more readily available and smaller than purpose-built solid-state drives and often have faster seek times than hard drives. When CompactFlash was first being standardized, even full-sized hard disks were rarely larger than 4 GB in size, and so
1836-581: The host device uses a suitable connector. Small cards consume around 5% of the power required by small disk drives and still have reasonable transfer rates of over 45 MB/s for the more expensive 'high-speed' cards. However, the manufacturer's warning on the flash memory used for ReadyBoost indicates a current draw in excess of 500 mA. CompactFlash cards for use in consumer devices are typically formatted as FAT12 (for media up to 16 MB), FAT16 (for media up to 2 GB, sometimes up to 4 GB) and FAT32 (for media larger than 2 GB).

1938-545: The limitations of the ATA standard were considered acceptable. However, CF cards manufactured after the original Revision 1.0 specification are available in capacities up to 512 GB. While the current revision 6.0 works in [P]ATA mode, future revisions are expected to implement SATA mode. CE-ATA is a serial MMC-compatible interface based on the MultiMediaCard standard. A variant of CompactFlash known as CFast
1989-428: The market in late 2009. At CES 2009, Pretec showed a 32 GB CFast card and announced that they should reach the market within a few months. Delock began distributing CFast cards in 2010, offering several card readers with USB 3.0 and eSATAp (power over eSATA) ports to support CFast cards. Seeking higher performance and still keeping a compact storage format, some of the earliest adoptors of CFast cards were in
2040-410: The memory chips in both cards have the same write speed specification. Although FAT16 is more wasteful of disk space with its larger clusters, it works better with the write strategy that flash memory chips require. The cards themselves can be formatted with any type of file system such as Ext , JFS , NTFS , or by one of the dedicated flash file systems . It can be divided into partitions as long as

However, a few models of xD card readers based on the Alauda chip do allow direct access (bypassing the above mechanisms) to an xD card's flash memory. These readers have been reverse-engineered and Linux drivers have been produced by the Alauda Project , which has documented the on-chip data structures of

2142-514: The new format is aimed at high-definition camcorders and high-resolution digital cameras, but the new cards are not backward compatible with either CompactFlash or CFast. The XQD card format was officially announced by the CompactFlash Association in December 2011. There are two main subdivisions of CF cards, 3.3 mm-thick type I and 5 mm-thick type II (CF2). The type II slot is used by miniature hard drives and some other devices, such as
2193-736: The only product employing CFast 2.0 cards was the Arri Amira digital production camera, allowing frame rates of up to 200 fps; a CFast 2.0 adapter for the Arri Alexa/XT camera was also released. On 7 April 2014, Blackmagic Design announced the URSA cinema camera, which records to CFast media. On 8 April 2015, Canon Inc. announced the XC10 video camera, which also makes use of CFast cards. Blackmagic Design also announced that its URSA Mini will use CFast 2.0. As of October 2016, there are
2244-958: The original cards. The Type H card, first released in November 2005, offers higher data rates than Type M cards (theoretically as much as 3 times faster). As of 2008, Type H cards were only available in 256 MB, 512 MB, 1000 MB, and 2000 MB capacities. Both Fuji and Olympus discontinued the production of Type H cards in 2008, citing high production costs. The Type M+ card, first released in April 2008, offers data rates 1.5 times that of Type M cards. As of 2008, cards are available only in 1 and 2 GB capacities. Olympus says that its xD cards support special "picture effects" when used in some Olympus cameras, though these software features are not intrinsically hardware-dependent. Type H and M+ cards however, are required in newer models to capture video at high rate (640×480 @ 30fps). Due to changes in
2295-481: The physical location to which a block is written. This process is called wear leveling . When using CompactFlash in ATA mode to take the place of the hard disk drive , wear leveling becomes critical because low-numbered blocks contain tables whose contents change frequently. Current CompactFlash cards spread the wear-leveling across the entire drive. The more advanced CompactFlash cards will move data that rarely changes to ensure all blocks wear evenly. NAND flash memory
2346-839: The raw flash memory. This can be done by using a hacked device driver for a USB card reader. CompactFlash CompactFlash ( CF ) is a flash memory mass storage device used mainly in portable electronic devices. The format was specified and the devices were first manufactured by SanDisk in 1994. CompactFlash became one of the most successful of the early memory card formats, surpassing Miniature Card and SmartMedia . Subsequent formats, such as MMC / SD , various Memory Stick formats, and xD-Picture Card offered stiff competition. Most of these cards are smaller than CompactFlash while offering comparable capacity and speed. Proprietary memory card formats for use in professional audio and video, such as P2 and SxS , are faster, but physically larger and more costly. CompactFlash's popularity
2397-425: The respective companies' logos, except for Kodak. Previously, xD competed primarily with Secure Digital (SD) cards, CompactFlash (CF), and Sony 's Memory Stick . Because of its higher cost and limited usage in products other than digital cameras, xD lost ground to SD, which is broadly used by cellular phones, personal computers, digital audio players and many other digital cameras. Olympus began to move away from
2448-408: The technical information required to produce xD-compatible devices. The memory format used is not well documented. It is difficult to study it directly, since most camera devices and most USB card readers do not provide direct access to the flash memory. Since the cards are controller-less, cameras and card readers must perform wear leveling and error detection. They normally hide the portion of
2499-419: The xD card. According to this information, xD card headers are similar to those used by SmartMedia, and include chip manufacturer information. At the raw hardware level, an xD card is simply an ordinary NAND flash integrated circuit in an unusual package. Comparing the pinout of an xD card to the pinout of a NAND flash chip in a standard TSOP package, one finds a nearly one-to-one correspondence between
2550-528: The xD format with the mid-2009 announcement of the E-P1 camera, which supported only Secure Digital memory cards. As of Spring 2010, all new Olympus cameras announced at the 2010 Consumer Electronics Show and Photo Marketing Association International Trade Show can use SD cards. This changeover to the SD card format has never been officially announced by Olympus Corporation. The higher-end DSLR cameras such as
2601-513: Was phased out in the late 2000s in favour of the SD card , which had been its primary competitor. The cards were developed by Olympus and Fujifilm , and introduced into the market in July 2002. Toshiba Corporation and Samsung Electronics manufactured the cards for Olympus and Fujifilm. xD cards were sold under other brands , including Kodak , SanDisk , PNY , and Lexar , but were not branded with
