What is the difference between a CF card and a memory stick? 20

Sony's seems to only be able to use memory sticks.,Memory sticks that don't support memory cards are actually a kind of memory cards.,It's just that the shape is different from the general.。

Generally speaking, memory cards are called memory sticks, but memory sticks are not stick-like things, but another name for memory cards, and the answer is that memory sticks are a type of memory cards! Common types of memory cards are SD cards, CF cards, TF cards, memory sticks, etc., memory sticks are generally a little more expensive than SD cards and CF cards Memory sticks are just a product designed by Sony for his own products, in order to distinguish from other brands.

The TF card is used by hand bai, and some Sony cameras also use this du

cards. The SD card is a universal adaptation card version for both cameras and SLRs. CF card is mainly used for full-frame SLR power.

The memory stick is a memory card exclusive to Sony, but it is now being phased out. XQD is a device owned by Sony and Nikon, which is used on the AX1E and D4 respectively, which is a high-end memory card. The WiFi card is actually an SD card, with a WiFi function.

They are all memory cards, but the specifications are different and the applicable devices are different.

Mobile phone memory card, computer memory card, game card, TV program card, can be a mobile phone connected to the computer network for free Internet access.

The differences are in compatibility, storage capacity, flash memory particles used, and data recoverability

The CF card is not only a storage device, but also a built-in controller, the biggest feature is good compatibility, no matter how large the capacity of the flash memory chipset, its external interface is the standard ATA IDE interface, and the external voltage is universal.

The purpose of SD cards is to increase the transmission speed by changing the transmission mode from serial to parallel. Most of the SD cards on the market now refer to SDHC cards, that is, "high-capacity SD memory cards", and the biggest feature is high capacity.

There are three types of flash memory particles: TLC, MLC, and SLC

SD cards are so cost-effective, most of their products use TLC particles (for example, Samsung EVO, Transcend, and Toshiba, their mainstream SD cards are all TLC particles), and better SD cards will use MLC particles.

As for CF cards, except for particularly cheap copycats, TLC particles will be used, the rest are MLC particles, and industrial-grade CF cards will also use SLC particles.

As long as the flash memory particles of the CF card are not broken, you can still seek data recovery. Disassemble the CF card, remove the flash memory particles, and take out the data with relevant instruments. As for the SD card, since there is only a chip structure inside, once it is broken, there is no way.

1. Different definitions:

CF card: The earliest is a data storage device used in portable electronic devices.

SD card: It is a new generation of memory device based on semiconductor flash memory.

2. Different storage methods:

CF card: non-flash.

SD card: flash memory type.

3. The shape and structure are different

CF card: SD card:

4. The rate is different

CF card: CF card has a write speed and read speed of up to 20MB s.

SD card: A normal SD card can transfer 900 KB seconds, while a high-speed SD card can transfer 10 MB seconds.

5. The scope of application is different

CF card: The F-mount has been widely used in PDAs, laptops, digital cameras, and a variety of devices including desktops.

The differences between SD card and CF card are as follows:

1. In terms of volume and size, the CF card is very large, while the SD card is very small.

2. From the stability of data storage, the CF card has an independent control circuit, which is much more stable than the SD card. In case of unexpected situations, it is very likely that the SD card will malfunction and cause the loss of important data.

3. In terms of product application, SD cards are mainly used in low-level camera products. CF cards are mainly used in high-end products, and in consumer products, it is almost impossible to see products that use CF cards.

1. Appearance time.

The CF card was first introduced by SanDisk in 1994; The SD card was jointly launched by Panasonic, Toshiba and SanDisk and released in August 1999.

2. Size and size.

CF size: 43mm x 36mm x ; The SD size is 32mm x 24mm x.

3. The capacity is different.

CF up to 12GB; The maximum SD size is 2GB.

The difference between the two:

1. The volume is different.

CF card is the earliest memory card launched, mainly used in high-end imaging products and some larger mobile devices. CF cards are larger because they are memory card specifications that were introduced earlier. However, the CF card has a fast storage speed, stable storage performance, and the card itself is not easy to be damaged, and the magnetic resistance is better than other cards.

SD card is a new generation of memory device based on semiconductor flash memory, due to its small size, fast data transfer speed, hot-swappable and other excellent characteristics.

2. The application is different.

CF cards have been widely used in PDAs, laptops, digital cameras, and a variety of devices including desktops.

3. Launch time.

SD card is a memory card format jointly developed by Panasonic Corporation, Toshiba Corporation and SanDisk Corporation of Japan, which is small in size and easier in terms of speed, so it is widely used in mobile devices, digital cameras are the most popular memory card, and most cameras support SD memory cards.

CF card is the earliest memory card, at the beginning of the widely used, after the increase of various memory cards, mainly used in high-end imaging products and some larger mobile devices.

The differences between CF card and SD card are as follows:

1. Difference in working mode: SD card is 9-pin and supports 14-bit bus mode; CF card 50-pin, support 16 bit bus mode.

2. The difference in security: CF generally uses MLC particles, industrial-grade CF cards will also use SLC particles, and most of the products of SD cards use TLC particles, in comparison, the security of CF cards is higher than that of SD cards.

3. The difference in stability: the built-in controller and ATA IDE interface of the CF card make the volume and cost increase, but the data is more secure.

4. Difference in volume and size: CF card has a thick appearance and is larger in size than SD card.

5. The difference in cost performance: SD card is cheaper, more cost-effective, and has better waterproof performance.

6. The difference in convenience: Compared with CF card, SD card is more convenient and easy to use, because most laptops and IMAC all-in-one computers are equipped with SD sockets.
