MiniSD and microSD memory cards have been designed for mobile phone technology. Depending on the manufacturer and factors such as read/write speed, the price of an SD card maybe half the cost of a CF card of the same data storage size. SD cards have replaced larger CompactFlash cards in many device applications due to their smaller size, lighter weight, and lower cost. They are not difficult to spot because of their chamfered contours. The SD card measures 32 mm x 24 mm x 2.1 mm. To save and transfer files, images, and songs between devices of ever-decreasing physical size, newer flash card formats have been introduced. Since flash memory devices are solid-state devices, they are less affected by shocks than rotating disks.Īlso see: NAND SSD: What Does NAND Flash Bring to SSD? Additional Flash Memory Card Formats The CompactFlash card includes error checking and correction (ECC) capabilities to detect errors and re-read the block. NAND flash is prone to frequent soft read errors. Most mass storage uses flash memory based on NAND. As with other flash devices, CompactFlash cards that use flash are limited in the number of erase/write cycles for any "block".Īlthough NOR flash memory has higher endurance, ranging from 10,000 to 1,000,000, they are not yet suitable for use with memory cards. The battery's rated life is the only reliability issue.

It allows the CF card to act as a solid-state drive in almost any operating system or BIOS and even in solid-state drives.Īlso see: What Is SATA Hard Drive? SATA Hard Drive Recovery ReliabilityĪfter disconnecting power, the original PC Card memory card uses the built-in battery to maintain data. This company makes adapters that allow CF cards to connect to PCI, PCMCIA, IDE and SATA connections. In early 2008, CFA showed a CompactFlash card with a built-in SATA interface. Later, to meet high-capacity needs, solid-state drives ( SSDs) replace two CF drives. Now solid-state cards have higher capacities (up to 512 GB). Before 2006, CF drives using magnetic media provided the largest capacity (up to 8 GiB. CapacityĬF 5.0 specification uses a 48-bit logical block addressing (LBA) to support a maximum capacity of 128 PiB. The actual transmission speed may be higher or lower than the speed shown on the card, depending on several factors. This is the same system used for CD-ROM and expresses the maximum transfer rate as a multiplier based on the transfer rate of the original audio CD data. SpeedĬompactFlash IDE (ATA) simulation speed is usually specified at the "x" level, such as 8x, 20x, 133x. The CF card can be used directly in the PC card slot via a plug adapter or used as an ATA with a passive adapter or reader. CompactFlash was originally built on Intel's NOR-based flash but has now moved to NAND technology. 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. The CF card has two main subdivisions, a Type I with a thickness of 3.3 mm and a Type II with a thickness of 5 mm (CF2).ĬompactFlash was originally built on Intel's NOR-based flash memory but has now turned to NAND technology.

CFast (also known as CompactFast) is based on a serial ATA interface. Traditional CompactFlash cards use Parallel ATA interfaces, but in 2008 CFast introduced a variant of CFast.
Now, continue to read this post from MiniTool to get more information about the CF card.
CompactFlash surpasses Miniature Card and SmartMedia as one of the most successful early memory card formats. The format was specified and the device was first manufactured by SanDisk in 1994.
