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 the Hasselblad CFV Digital Back for the Hasselblad series of medium format cameras.

Jan 7, 2015 · At this point in time, CF cards come in a wide variety of sizes from 4GB to 512GB – quite a range in storage space!. Prices range anywhere from $10 to $900 depending on the size and speed of the CF card.

Jul 11, 2019 · With the introduction of 48-bit addressing in CompactFlash Revision 5.0 (released in 2010), the theoretical maximum size for a CompactFlash card jumped from 137 gigabytes to 144 petabytes...

Based on the Parallel Advanced Technology Attachment (ATA) interface, CF cards measure 42.8 millimeters by 36.4 mm -- about the size of a matchbook. They're available with storage capacities ranging up to 512 gigabytes.

Jan 31, 2025 · CompactFlash cards, also known as CF (Compact Flash) cards, are a type of solid-state storage device that was widely used in the early 2000s for storing data, images, and audio files in cameras, MP3 players, and other portable devices.

Consider both size and speed when looking at CF cards. There is a wide variety of sizes from 4GB to 512 GB, which will vary pricing depending on setwo factors. The read speed on a CF card is essential for filmmakers and photographers to know, but it's not as crucial because the write speeds will always be slower.

Jan 16, 2018 · 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 in some specialty cameras, but is not as common. 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.

Apr 19, 2020 · A: Although CompactFlash and CFast cards have the same dimensions of 42.8*36.4*3.3mm, CompactFlash cards are compliant with CompactFlash Specification 1.0 to 6.0 and PATA connectors. CFast cards are considered the next-gen CompactFlash since they support SATA III interface, enabling much faster write/read speeds.

Type C: 54mm (width) x 74mm (length) x 4.8mm (thickness, including label area) CFast cards supporting the current CFast 1.1 specification are based on the Serial ATA Gen II interface (SATA-II) and support bus speeds up to 300MB/s. These cards have largely been used within industrial markets.

Mar 5, 2025 · There are four main card speeds: original CF, CF high speed (using CF + /CF2.0), faster CF 3.0 standard and faster CF 4.0 standard adopted since 2007. CompactFlash was originally built on Intel’s NOR-based flash but has now moved to NAND technology.
