What Are the Different Kinds of Memory Cards Used in Electronic Devices?

Memory cards serve to store all your critical data and even precious memories so that you may retrieve them at a later time. There are many different types of memory cards, those of which depend on the device at hand. For example, cameras in particular have a wide range of memory card types, those of which vary based on the storage capacity, size, and physical shape of the card. Some manufacturers like Canon prefer CompactFlash (CF) memory cards while others opt for smaller Secure Digital (SD) types.

Regardless of the memory card type you choose, one should always consider the device’s specifications. For instance, Micro Secure Digital cards can be used with an adapter, while SanDisc memory cards are more compact. Depending on one’s needs, memory card types may vary. Nonetheless, the most common types include CF cards and SD cards.

CF cards are regarded as the memory cards preferred by professional photographers. In fact, most high-end DSLRs utilize CF cards. They are physically bigger than SD cards and not as common. Furthermore, they have bigger capacities and can run at high speeds. Meanwhile, Secure Digital cards are the basic format of the SD card. They are small in size but not as fast as other SD cards. In addition, SD cards are limited to 4GB and anything above this memory capacity would require an SDHC which can store up to 64GB of data or SDXC card that stores more than 64GB.

Micro Secure Digital (MicroSD) cards, on the other hand, are micro versions of an SD card. Their physical size is about 15 mm x 11 mm and are 1 mm thick. The Micro Secure Digital High Capacity (MicroSDHC) card is similar to the SDHC card, storing up to 32GB of data. This card was introduced in 2007 and has the capacity to transfer up to 10MB per second. The Micro Secure Extended Capacity (MicroSDXC) card is the same as the SDXC, though its transfer speed outperforms its counterparts and it stores anywhere from 32GB to 2TB of data.

Finally, developed by Fujifilm and Olympus, the Extreme Digital Picture Card (xD) is a removable flash memory that is specifically designed for use in digital cameras. It is usually 20 mm x 25 mm and a thickness of 1.7 mm. With so many memory card options, it is important that you consider what your device necessitates and what your expectations are. Once you have narrowed down your specifications, finding a reputable distributor of electronic parts and hardware devices is paramount.
