What is a CompactFlash card?
CompactFlash (CF) is a flashmass storage deviceprimarily for portable electronic devices.
The format was specified and the equipment was first manufactured by SanDisk in 1994.
CompactFlash surpasses Miniature Card and SmartMedia as one of the most successful early memory card formats.
Now, continue to read this post fromMiniToolto get more information about the CF card.
Traditional CompactFlash cards useParallel ATAinterfaces, but in 2008 CFast introduced a variant of CFast.
CFast (also known as CompactFast) is based on a serial ATA interface.
CompactFlash was originally built on Intels NOR-based flash memory but has now turned to NAND technology.
CompactFlash was originally built on Intels NOR-based flash but has now moved to NAND technology.
Before 2006, CF drives using magnetic media provided the largest capacity (up to 8 GiB.
Now solid-state cards have higher capacities (up to 512 GB).
Later, to meet high-capacity needs, solid-state drives (SSDs) replace two CF drives.
In early 2008, CFA showed a CompactFlash card with a built-in SATA interface.
This company makes adapters that allow CF cards to connect to PCI, PCMCIA,IDE and SATAconnections.

The batterys rated life is the only reliability issue.
Most mass storage uses flash memory based on NAND.
NAND flash is prone to frequent soft read errors.
The CompactFlash card includes error checking and correction (ECC) capabilities to detect errors and re-read the block.
Since flash memory devices are solid-state devices, they are less affected by shocks than rotating disks.

The SD card measures 32 mm x 24 mm x 2.1 mm.
They are not difficult to spot because of their chamfered contours.
MiniSD and microSD memory cards have been designed for mobile phone technology.
XQD card uses first-generation PCIe connection, speed is up to 250 MBps.
