What are the different types of CompactFlash cards?
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.
What is CompactFlash Type 1?
CompactFlash is the world’s most popular removable mass storage device. The CompactFlash card is about the size of a matchbook and only weighs half an ounce. The card was designed based on the popular PC Card (PCMCIA) standard and can easily be slipped into these slots with the use of a low-cost adapter.
What is the difference between CF Type 1 and Type 2?
The only difference between the CF Type I and Type II memory cards is their thickness. CF Type I card is 3.3mm thick, while CF Type II card is 5mm thick. CF Type I cards can fit into CF Type I and Type II slots, whereas CF Type II cards can only fit into CF Type II slots.
What is CF in computer?
CompactFlash (CF) is a removable storage device used for mass storage in portable electronic machines, such as PCs. Based on non-volatile technology (flash memory), CF does not require a battery.

What is the difference between CFexpress Type A and Type B?
Type B cards have 2 PCIe lanes and a maximum theoretical speed of 2,000MB/s. Type A cards are smaller and feature a single PCIe lane for a maximum theoretical speed of 1,000MB/s. These cards are designed for smaller cameras and devices in which size is more important than speed.
What is the difference between CF and CFexpress?
CFexpress cards are the latest generation of what was once CompactFlash (CF card). These are high speed memory cards designed to keep up with the demands of the latest cameras in terms of both high-resolution photos and video. CFexpress cards use an interface called PCIe 3.0, as well as NVMe 1.3 protocols.
