Memory card is a kind of quick flash data storage devices and commonly used in electronic products such as digital camera, digital vidicon, PDA, and music player. It is small in size, convenient to take, and easy to use. At the same time, as most memory cards have good compatibility, they can be used to swap data among different digital products. In recent years, with the continuous development of digital products, the capacity of memory card is promoted unceasingly and memory card is popularized quickly. Nowadays, we can see numerous types of memory cards, such as CF, MMC series, and SD series. Here, let me introduce some features of different types of memory cards.
At first, let's talk about CF card. It
is one of the memory cards which have a quite long history. Features are as
follows: big storage capacity, low costs, good compatibility, and so on.
However, it is larger than other memory cards in size. We can divide CF card
into 2 models, namely CF I and CF II. Although CF card has a pretty long
history, it is still widely used in PDA, notebook computer, digital camera,
desktop computer and other devices.
Since CF card is large in size,
Infineon and SanDisk jointly released MMC card which is smaller than CF card in
1997, and its specification is 32mm×24mm×1.4mm. Although MMC
technology has been replaced by SD technology gradually, MMC card still can be
read by the device which is compatible with SD card. Therefore, MMC card is
still applied in digital camera, mobile phone (like Siemens MP3 and
mobile phone), and some PAD products.
SD series card is one of
most widely used memory cards, because there are so many SD series cards, such
as SD card, mini SD card, micro SD, and T-Flash. Compared with other types of
memory cards, SD card is safer and parts of SD series cards are equipped with
write-protect switch. Its specification is quite similar to MMC, so it has
replaced MMC gradually.
All above are brief introductions to several
different kinds of memory cards. As to other types of memory cards, there is no
need to introduce them one by one.
Problems frequently emerging
on memory card
As memory card is applied wider and wider, accidents
emerging on memory card become more and more, and memory card data loss is
commonly seen. When bringing inconvenience, memory card data loss may bring us
serious economic losses, too. So, when memory card data loss happens, the best
method is to recover memory card data as soon as possible. But for common users,
it is not easy to recover memory card data. But now, users do not need to be
worried, because MiniTool Solution Ltd.
releases a piece of professional data recovery software - MiniTool
Power Data Recovery. Moreover, it is also a piece of free memory card recovery
software. Therefore, MiniTool Power
Data Recovery is the best choice for memory card recovery.
From the above main interface of the free memory card recovery software, we can
see its data recovery functions clearly. The software divides data recovery
functions into different modules, and users can select corresponding module to
recover lost data according to different data loss situations. Users can get
detailed data recovery operations of the free memory card recovery software by
